  • Loading UITableView form UIView

    - by Amarpreet
    Hi Guys, I am working on navigation based application in which i can navigate to many views starting from default UITableView which is starting view in application template. I have added another UIView and added tableView control on that UIView. I am calling that view form one of the many views on a button click. Its showing the view but not populating the data in the table. And I also want to handle the event when user taps on the cell of the table of that view. Below is the Code I am using on button click: if(self.lstView == nil) { ListViewController *viewController = [[ListViewController alloc] initWithNibName:@"ListViewController" bundle:nil]; self.lstView = viewController; [viewController release]; } [self.navigationController pushViewController:lstView animated:YES]; self.lstView.title = @"Select";//@"System"; [self.lstView.tblList.dataSource fillList]; Below is the fillList function code: -(NSArray *)fillList { NSArray *tempArray = [[[NSArray alloc] initWithObjects:@"Item 1" , @"Item 2" , nil]autorelease]; return tempArray; } I am pretty new in Iphone programming and don't have much understanding. Helping with detailed description and code will be highly appreciated. Thanks.

  • Design pattern to keep track UITableView rows correspondance to underlying data in constant time.

    - by DenNukem
    When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. there is no ordering "key" that represents the sort order. There is also a corresponding UITableView that shows one row per addressbook entry. When UITableView queries the datasource I query the NSMUtableArray populated with my entries and return required data in constant time for each row. However, if there is a change in underlying model I am getting a notification "Joe Smith, id#123 has been removed". Now I have a dilemma. A naive approach would be to scan the array, determine the index at which Joe Smith is and then ask UITableView to remove that precise row from the view, also removing it form the array. However, the scan will take linear time to finish. Now I could have an NSDictionary which allows me to find Joe Smith in constant time, but that doesn't do me a lot of good because I still need to find his ordinal index within the array in order to instruct UITableView to remove that row, which is again a linear search. I could further decide to store each object's ordinal inside the object itself to make it constant, but it will become outdated after first such update as all subsequent index values will have changed due to removal of an object. So what is the correct design pattern to accurately reflect model changes in the UITableView in costant (or at least logarithmic) time?

  • Cannot edit values of DataGridView bound to a BindingList

    - by m_oLogin
    Hello community, I have trouble editing a databound bindinglist. Let me illustrate it with the following: Say I have the Person class: public Class Person{ private string m_firstname; private string m_lastname; public string FirstName{get;set;} public string LastName{get;set;} public Person{ ... } } I then have a containing class called Population: public class Population{ private BindingList<Person> m_lstPerson = new BindingList<Person>(); private string m_countryName; public BindingList<Person> ListPerson{get; set;} public string CountryName { get; set; } } I then have on one form a first datagridview with DataSource = m_lstPopulation (BindingList). The binding works like a charm when working with the Population objects. When I double click, it opens up a dialog form showing the object details. One tab in the details holds a datagridview bound to that population's ListPerson. The second datagridview displays fine. However, I cannot edit or add cells in this datagridview. None of the columns is set to read-only. In fact, both datagridview have just about the same parameters. What am I missing? It seems that a lock has been placed on the Population object so that its inner fields cannot be edited... Please advise. Thanks.

  • Recommendations, Asp.Net ObjectDataSource bind result of webservice call

    - by DerDres
    I need recommendations on how to solve / structure a solution to the following problem. In an asp.net web application i'll have to visualise results returned from a web service call. Im planning to use a repeater server control and bind this with an objectdatasource. The service returns a result of the form: public class SearchResult : IExtensibleDataObject { [DataMember] public Guid SearchId { get; set; } [DataMember] public DateTime Timestamp { get; set; } [DataMember] public int Offset { get; set; } [DataMember] public int TotalResults { get; set; } [DataMember] public IList<ResultDocumentData> Documents { get; set; } It is the collection of Documents that I need to visualise with a repeater which will be associated with an ObjectDataSource. The datasource should work on the type ResultDocumentData; the collection property in the class SearchResult. I think I need to wrap the call to the webservice in a dataaccess layer class, that will have a getDocuments method returning an IList, that the ObjectDataSource can use as its SelectMethod. I think I could make this work, but I would like to know how to do it in an elegant way. Can you give me general recommendations and/or recommendations for the following: WebProject Folderstructure + naming Naming conventions for the name of the service wrapper class Creating the service reference

  • C# HTML tags inside GridView

    - by Geo Ego
    I have a SharePoint web part that I wrote in C# which is used to display SQL Server data based on user selections. I pull the data with a DataReader, fill a DataSet with it, and set that DataSet as the DataSource in a GridView and add that control to my page. The only problem I'm facing is that line breaks in the data fields are not being rendered at all. I'm simply getting a block of text that ignores the breaks that are present in the database when it's rendered to HTML. I tried a regex: Regex rgx = new Regex("\n"); string inputStr = Convert.ToString(dr[x]); string outputStr = rgx.Replace(inputStr, "<br />"); newRow[ds3.Tables["Bobst Specs 3"].Columns[x]] = outputStr; While that does detect and replace the newlines, I merely get the text "" with no line breaks. I also tried changing my SQL query to something along the lines of: SELECT REPLACE (fldCustomerName, '. ', '.' + @NewLineChar) This apparently renders more newlines. I can see that they are present, because if I also insert the regex they are affected, but do not create line breaks. I'm not sure how to replace these, and what with, to get the lines to actually break.

  • Set the selected item for a combobox in a datagrid

    - by JingJingTao
    I am using a datagrid which has many combobox fields in it, when I click the datagrid combobox the selected item or highlighted value is the last item in the list, but I would like it to highlight the first(top) item in the list. I know for just a combobox, all I need to do is change the combobox.selecteditem or combobox.selectedindex, but I'm not sure what to do in this case. I have binded the combobox to a table in the database and used a datatable to store the combobox values and then I add a row to the datatable, I think the reason the last item in the combobox is highlighted is because I added a row to the datatable. Thank you for your help. String strGetTypes = "SELECT holidaycodeVARCHAR4Pk, codedescVARCHAR45 FROM holidaytype ORDER BY holidaycodeVARCHAR4Pk Desc"; DataTable dtHolidayType = new DataTable(); MySqlDataAdapter dbaElements = new MySqlDataAdapter(strGetTypes, ShareSqlSettings.dbConnect); dbaElements.Fill(dtHolidayType); DataGridViewComboBoxCell cboxDays = new DataGridViewComboBoxCell(); cboxDays.DataSource = dtHolidayType; cboxDays.DisplayMember = "codedescVARCHAR45"; cboxDays.ValueMember = "holidaycodeVARCHAR4Pk"; //Blank row dtHolidayType.Rows.Add(1); // gridDailyEmp.Rows[j].Cells[day] = cboxDays;

  • DataGridView not displaying a row after it is created

    - by joslinm
    Hi, I'm using Visual Studio 10 and I just created a Database using SQL Server CE. Within it, I made a table CSLDataTable and that automatically created a CSLDataSet & CSLDataTableTableAdapter. The three variables were automatically created in my MainWindow.cs class: cSLDataSet cSLDataTableTableAdapter cSLDataTableBindingSource I have added a DataGridView in my Form called dataGridView and datasource cSLDataTableBindingSource. In my MainWindow(), I tried adding a row as a test: public MainWindow() { InitializeComponent(); CSLDataSet.CSLDataTableRow row = cSLDataSet.CSLDataTable.NewCSLDataTableRow(); row.File_ = "file"; row.Artist = "artist11"; row.Album = "album"; row.Save_Structure = "save"; row.Sent = false; row.Error = true; row.Release_Format = "release"; row.Bit_Rate = "bitrate.."; row.Year = "year"; row.Physical_Format = "format"; row.Bit_Format = "bitformat"; row.File_Path = "File!!path"; row.Site_Origin = "what"; cSLDataSet.CSLDataTable.Rows.Add(row); cSLDataSet.AcceptChanges(); cSLDataTableTableAdapter.Fill(cSLDataSet.CSLDataTable); cSLDataTableTableAdapter.Update(cSLDataSet); dataGridView.Refresh(); dataGridView.Update(); } In regards to the DataSet methods I tried calling, I had been trying to find a "correct" way to interact with the adapter, dataset, and datatable to successfully show the row, but to no avail. I'm rather new to using SQL Server CE Database, and read a lot of the MSDN sites & thought I was on the right track, but I've had no luck. The DataGridView shows the headers correctly, but that new row does not show up.

  • If Then Else Statement Condition Being Ignored?

    - by Matma
    I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees. BOTH side of this if then else statement are being executed? Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation... The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change? please show me the stupid mistake im making using vs2005 if it matters. Dim dset As DataSet = New DataSet If (CboCustomers.SelectedValue IsNot Nothing) AndAlso (CboCustomers.SelectedValue <> "") Then Dim Sql As String = "Select sal.SalesOrderNo As SalesOrder,cus.CustomerName,has.SerialNo, convert(varchar,sal.Dateofpurchase,103) as Date from [dbo].[Customer_Table] as cus " & _ " inner join [dbo].[Hasp_table] as has on has.CustomerID=cus.CustomerTag " & _ " inner join [dbo].[salesorder_table] as sal On sal.Hasp_ID =has.Hasp_ID Where cus.CustomerTag = '" & CboCustomers.SelectedValue.ToString & "'" Dim dap As SqlDataAdapter = New SqlDataAdapter(Sql, FormConnection) dap.Fill(dset, "dbo.Customer_Table") DGCustomer.DataSource = dset.Tables("dbo.Customer_Table") Else Dim erm As String = "wtf" End If

  • Can I use loops in repeater? Is it recommended?

    - by iTayb
    My datasource has an Rating dataItem contains an integer from 0 to 5. I'd like to print stars accordignly. I'm trying to do it within Repeater control: <b>Rating:</b> <% for (int j = 1; j <= DataBinder.Eval(Container.DataItem, "Rating"); j++) { %> <img src="App_Pics/fullstar.png" /> <% } for (int j = 1; j <= 5 - DataBinder.Eval(Container.DataItem, "Rating"); j++) { %> <img src="App_Pics/emptystar.png" /> <%} %> I get the error The name 'Container' does not exist in the current context. It is weird, because when I used <%# DataBinder.Eval(Container.DataItem, "Name")%> a line before, it worked great. Is it clever to include loops in my aspx page? I think it's not very convenient. What's my alternatives? What's that # means? Thank you very much.

  • How do I load an XML document, add and remove nodes, then apply it to a ASP DataGrid control?

    - by JFOX
    I have a pretty simple operation but am struggling with how to implement it. I am loading XML from an external data source using a DataSet.ReadXml(), the creating a new XMLDataDocument from that data set, then syncing the Dataset back to the XMLDataDocument like so: doc = new XmlDataDocument(dsDataSet); dsDataSet.EnforceConstraints = false; dsDataSet= doc.DataSet; Once loaded I do two things to the XmlDataDocument: Loop through and check if a purely meta node, count, exists right beneath the root node and if so remove it. a thumb node exists in a second level nodelist and if not, create and append it. This is all going a expected because the result of doc.save() looks correct. Where I'm having an issue is updating the Dataset, which is being applied as the data source for an ASP DataGrid. Once all the above XMLDoc manipaulation is done I do this: dsDataSet.Merge(doc.DataSet); dsDataSet.AcceptChanges(); I then apply the data set to the grid control: dgList.DataSource = dsDataSet; dgList.DataBind(); But, when I do this I get this error on the site: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'thumb'. What did I miss?

  • wpf error template - red box still visible on collapse of an expander

    - by Andy Clarke
    Hi, I'm doing some validation on the DataSource of TextBox that's within an Expander and have found that once a validation error has been triggered, if I collapse the Expander, the red box stays where the TextBox would have been. <Expander Header="Blah Blah Blah"> <TextBox Name="TextBox" Validation.ErrorTemplate="{DynamicResource TextBoxErrorTemplate}" Text="{Binding Path=Blah, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" /> </Expander> I've tried to get round this by binding the visibility of the Error Template to the Expander, however I think there's something wrong with the binding. <local:NotVisibleConverter x:Key="NotVisibleConverter" /> <ControlTemplate x:Key="TextBoxErrorTemplate"> <DockPanel> <Border BorderBrush="Red" BorderThickness="2" Visibility="{Binding Path=IsExpanded, Converter={StaticResource NotVisibleConverter}, RelativeSource={RelativeSource AncestorType=Expander}}" > <AdornedElementPlaceholder Name="MyAdorner" /> </Border> </DockPanel> <ControlTemplate.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> I guess I've gone wrong with my binding, can someone put me back on track please? Alternatively does anyone know another solution to the ErrorTemplate still being visible on the collapse of an Expander?

  • Windows Mobile : How to bind dropdown's selectedvalue to a column in table A and the list data to a

    - by Rob
    Hi, I am trying to learn the basics of Windows Mobile development against SQL CE and have come across a basic problem. I have two tables. One called Customers that stores customer info and has an identity column called ID as the primary key. The other table is called Orders which has a column called CustomerID (the FK constraint is present). I have added a DataSet to the project that contains both tables and have autogenerated the edit/view forms. This has produced a text control for the CustomerID column in the Order table for the new/edit form and I deleted it and replaced it with a dropdown list. Then, using the 'Advanced' databinding options (in Properties) I set the datasource of the list to the Customers table setting the value to the ID field and the text to the CustomerName field. I then set the SelectedValue of the list box to the CustomerID field of the Orders dataset. So far so good. When I run the app in the emulator and view the 'New' form for Orders the Customer dropdown is indeed populated with a list of customer names and I can select one and happily create a new order successfully. This is confirmed when I see the order appear in the Orders Grid form. However, when I then click on the order in the grid and then select 'Edit' the order loads but the dropdown always shows the first customer in the list and doesn't seem to bind the SelectedValue to the Orders dataset CustomerID field. Now I am an ASP.NET guy and normally hand craft the DAL and it's binding to the UI so I'm not entirely sure where to look to investigate what is going wrong here as this is all generated code. I am sure it is something very trivial but any pointers would be appreciated. My gut feeling is that the SelectedValue and the Customers.CustomerID values do not match for some reason? Many thanks, Rob.

  • How do I DYNAMICALLY cast in C# and return for a property

    - by ken-forslund
    I've already read threads on the topic, but can't find a solution that fits. I'm working on a drop-down list that takes an enum and uses that to populate itself. i found a VB.NET one. During the porting process, I discovered that it uses DirectCast() to set the type as it returns the SelectedValue. See the original VB here: http://jeffhandley.com/archive/2008/01/27/enum-list-dropdown-control.aspx the gist is, the control has Type _enumType; //gets set when the datasource is set and is the type of the specific enum The SelectedValue property kind of looks like (remember, it doesn't work): public Enum SelectedValue //Shadows Property { get { // Get the value from the request to allow for disabled viewstate string RequestValue = this.Page.Request.Params[this.UniqueID]; return Enum.Parse(_enumType, RequestValue, true) as _enumType; } set { base.SelectedValue = value.ToString(); } } Now this touches on a core point that I think was missed in the other discussions. In darn near every example, folks argued that DirectCast wasn't needed, because in every example, they statically defined the type. That's not the case here. As the programmer of the control, I don't know the type. Therefore, I can't cast it. Additionally, the following examples of lines won't compile because c# casting doesn't accept a variable. Whereas VB's CType and DirectCast can accept Type T as a function parameter: return Enum.Parse(_enumType, RequestValue, true); or return Enum.Parse(_enumType, RequestValue, true) as _enumType; or return (_enumType)Enum.Parse(_enumType, RequestValue, true) ; or return Convert.ChangeType(Enum.Parse(_enumType, RequestValue, true), _enumType); or return CastTo<_enumType>(Enum.Parse(_enumType, RequestValue, true)); So, any ideas on a solution? What's the .NET 3.5 best way to resolve this?

  • Parse numbers in singe textbox for query

    - by Joshua Slocum
    I’ve built a webform in Visual Web Developer Express 2008 to help me with my work. I use a webform to run query requests that are emailed to me. The inputs are in this format 12312 12312 12312 12312 12312 12312 12312 12312 I enter the first number in a textbox and the second number in another textbox and click a button that runs a query and returns the results in a gridview(single row). string strConn, strSQL; strConn = AppConfig.Connection strSQL = 'select fields from table where FirstNum=:FirstNum and SecondNum=:SecondNum'; using (OracleConnection cn = new OracleConnection(strConn)) { OracleCommand cmd = new OracleCommand(strSQL, cn); cmd.Parameters.AddWithValue(":FirstNum", txtFirstNum.Text); cmd.Parameters.AddWithValue(":SeconNum", txtSecondNum.Text); cn.Open(); using (OracleDataReader rdr = cmd.ExecuteReader()) { dgResults.DataSource = rdr; dgResults.DataBind(); } cn.Close(); } I had an idea to help me speed up my work. I’d like to be able to past both numbers in a single textbox ( like this 12312 12312 ) and have the code parse out the nubmers for the query. Or even better would be to past all of them in a multiline textbox like this 12312 12312 12312 12312 12312 12312 12312 12312 And have them all parsed and the query run for each line and the results all output to one gridview. I’m just not sure how to approach this. Any suggestions would be appreciated. Thank you.

  • Dynamically populated NSPopUpButtonCell menu in an NSOutlineView

    - by Mo
    I’m working with an NSOutlineView which has two columns. My dataSource supplies the outline view with a tree of items of a custom class which represents file types (that is, you initialise it with a UTI). The first column is the display name of the file type (e.g., “Source code”, “Interface Builder NIB document”, etc.). The second column is an NSPopUpButtonCell which is supposed to allow the user to pick a handler for the given document type (think of Xcode’s “File Types” preference pane, and you’re pretty much there). I can generate an NSMenu for a given item in the tree, populated with options based upon the Launch Services database entries for the UTI, complete with the relevant application icon and and so on. In fact, the menu itself works wonderfully, populated by way of NSPopUpButtonCellWillPopUpNotification. The problem is, try as I might, the cell when the menu isn’t popped up always contains precisely one of two things: either an empty string, or the default text for the cell, the former if the result of -handlerName on the item (the attribute assigned to the column) is non-nil, the latter otherwise. Moreover, I’m manually calling -selectItem: on the NSPopUpButtonCell instance, which just seems Wrong. In contrast, the left-hand column, which is just an NSTextFieldCell, everything just works (although granted, all it’s got to do is read the value from the item and present it). (Disclaimer: I’m fairly new at Cocoa UI stuff; I know Objective-C, and lots of other programming languages, but I’ve not a huge amount of experience of building Mac OS X UIs, so be gentle).

  • Referencing object's identity before submitting changes in LINQ

    - by Axarydax
    Hi, is there a way of knowing ID of identity column of record inserted via InsertOnSubmit beforehand, e.g. before calling datasource's SubmitChanges? Imagine I'm populating some kind of hierarchy in the database, but I wouldn't want to submit changes on each recursive call of each child node (e.g. if I had Directories table and Files table and am recreating my filesystem structure in the database). I'd like to do it that way, so I create a Directory object, set its name and attributes, then InsertOnSubmit it into DataContext.Directories collection, then reference Directory.ID in its child Files. Currently I need to call InsertOnSubmit to insert the 'directory' into the database and the database mapping fills its ID column. But this creates a lot of transactions and accesses to database and I imagine that if I did this inserting in a batch, the performance would be better. What I'd like to do is to somehow use Directory.ID before commiting changes, create all my File and Directory objects in advance and then do a big submit that puts all stuff into database. I'm also open to solving this problem via a stored procedure, I assume the performance would be even better if all operations would be done directly in the database.

    I have the following type declaration and Oracle function: CREATE OR REPLACE TYPE var_outcomes_results IS TABLE OF VARCHAR2(80); CREATE OR REPLACE FUNCTION getValuesAbove(in_nodeID IN table1.KEY_SL%TYPE, in_variable IN VARCHAR2) RETURN var_outcomes_results IS currentID table1.KEY_SL%TYPE; results var_outcomes_results; currentIndex integer := 0; BEGIN currentID := in_nodeID; WHILE currentID != null LOOP FOR outcomeRecord IN (select distinct a.PARENT, b.NAME, c.OUTCOME from table1 a left outer join table2 b on a.KEY_SL = b.KEY_SL left outer join table3 c on b.VAR_ID = c.VAR_ID where a.KEY_SL = currentID) LOOP currentID := outcomeRecord.PARENT; IF lower(outcomeRecord.NAME) = lower(in_variable) AND outcomeRecord.OUTCOME != null THEN currentIndex := currentIndex + 1; results(currentIndex) := outcomeRecord.OUTCOME; END IF; END LOOP; END LOOP; RETURN results; END; I have the following Java function: public List<Object> getAboveValues(String variable, Integer nodeID) { Connection connection = null; CallableStatement callableStatement = null; try { connection = dataSource.getConnection(); callableStatement = connection.prepareCall("begin ? := getValuesAbove(?,?); end;"); callableStatement.registerOutParameter(1, OracleTypes.ARRAY); callableStatement.setInt(2, nodeID); callableStatement.setString(3, variable); callableStatement.execute(); System.out.println(callableStatement.getObject(1)); } catch( SQLException e ) { logger.error("An Exception was thrown in getAboveValues: " + e); } finally { closeDataResources(callableStatement, connection); } } However, when I execute the function, I get the following error message: "ORA-03115: unsupported network datatype or representation" What am I doing wrong? Any ideas/suggestions would be appreciated. Thanks, B.J.

  • entity framework - getting null exception using foreign key

    - by Nick
    Having some trouble with what should be a very simple scenario. For example purposes, I have two tables: -Users -Comments There is a one-to-many relationship set up for this; there is a foreign key from Comments.CommentorID to Users.UserID. When I do the LINQ query and try to bind to a DataList, I get a null exception. Here is the code: FKMModel.FKMEntities ctx = new FKMModel.FKMEntities(); IQueryable<Comment> CommentQuery = from x in ctx.Comment where x.SiteID == 101 select x; List<Comment> Comments = CommentQuery.ToList(); dl_MajorComments.DataSource = Comments; dl_MajorComments.DataBind(); In the ASPX page, I have the following as an ItemTemplate (I simplified it and took out the styling, etc, for purposes of posting here since it's irrelevant): <div> <%# ((FKMModel.Comment)Container.DataItem).FKMUser.Username %> <%# ((FKMModel.Comment)Container.DataItem).CommentDate.Value.ToShortDateString() %> <%# ((FKMModel.Comment)Container.DataItem).CommentTime %> </div> The exception occurs on the first binding (FKMUser.Username). Since the foreign key is set up, I should have no problem accessing any properties from the Users table. Intellisense set up the FKMUser navigation property and it knows the properties of that foreign table. What is going on here??? Thanks, Nick

  • ListBox Items Not Visible after DataBinding

    - by SidC
    Good Evening All, I am writing a page that allows users to search a parts table, select quantities and a listbox is to be populated with gridview values. Here's a snippet of my aspx page: <asp:ListBox runat="server" ID="lbItems" Width="155px"> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> </asp:ListBox> Here's the relevant contents of codebehind: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Define DataTable Columns as incoming gridview fields Dim dtSelParts As DataTable = New DataTable Dim dr As DataRow = dtSelParts.NewRow() dtSelParts.Columns.Add("PartNumber") dtSelParts.Columns.Add("NSN") dtSelParts.Columns.Add("PartName") dtSelParts.Columns.Add("Qty") 'Select those gridview rows that have txtQty <> 0 For Each row As GridViewRow In MySearch.Rows Dim textboxText As String = _ CType(row.FindControl("txtQty"), TextBox).Text If textboxText <> "0" Then 'Create the row dr = dtSelParts.NewRow() 'Fill the row with data dr("PartNumber") = MySearch.DataKeys(row.RowIndex)("PartNumber") dr("NSN") = MySearch.DataKeys(row.RowIndex)("NSN") dr("PartName") = MySearch.DataKeys(row.RowIndex)("PartName") 'Add the row to the table dtSelParts.Rows.Add(dr) End If Next 'Need to send items to Listbox control lbItems lbItems.DataSource = New DataView(dtSelParts) lbItems.DataValueField = "PartNumber" lbItems.DataValueField = "NSN" lbItems.DataValueField = "PartName" lbItems.DataBind() End Sub The page runs fine in that my search functiobnality is intact, and I can input quantity values into my gridview's textbox. When I click Add to Quote the Listbox receives focus, but no list items are visible. I've created several list items in the aspx page, however I don't know how to populate the contents of my datatable in the listbox. Can someone help a newbie with this, seemingly, easy issue? Thanks, Sid
