  • Scrolling a Div programatically using say Javascript

    - by SARAVAN
    Hi I have a jqgrid which is embedded in a Div. I am deleting records from the grid and reloading the grid using grid.Trigger('reload'). The width of the grid is considerably high so it has a scroll bar. Now I scrolled through the end of the grid horizontally before deleting records. Each time I delete the records and reload the grid, the column headers and their values are slightly misaligned. When I move the scroll bar back to original position or just move the scroll bar slightly they are aligned properly. So I thought its better to move the scroll bar to its inital position when the grid reloads. How can a scroll bar be programatically moved using javascript. Or is there any other way to solve my problem?

  • Set .aspx page title to that of an Eval

    - by user1860529
    I am trying to use an <%# Eval("name") %> to be the title of my page. I can't seem to figure out any solutions online. I have tried the other StackOverflow question but that did now work either. The page is a bio.aspx and on the site it is displayed as bio.aspx?id=123 so the page title needs to vary depending on the ID. I figured I could just use the Eval("name") but no luck yet. I currently am using JavaScript: window.onload = function() { document.title = '<%# Eval("name") %> | Title Line'; } This works, but it still leaves the title tags empty, and it's kind of spammy. Here is the codebehind: using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; public partial class DoctorBio : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Page.Title = "Your Page Title"; HtmlMeta metaDescription = new HtmlMeta(); metaDescription.Name = "description"; metaDescription.Content = "brief description"; Page.Header.Controls.Add(metaDescription); HtmlMeta metaKeywords = new HtmlMeta(); metaKeywords.Name = "keywords"; metaKeywords.Content = "keywords, keywords"; Page.Header.Controls.Add(metaKeywords); } protected void SetPageTitle(object title) { this.Title = title.ToString(); } protected string ReplaceLineBreaks(object text) { string newText = text as string; if (newText == null) { return string.Empty; } return newText.Replace("\r\n", "<br />"); } }

  • Finding ALL positions of a substring in a large string in C#

    - by Tommy
    Alright, so what i have, is a large string i need to parse, and what i need to happen, is find all the instances of extract"(me,i-have lots. of]punctuation, and store them to a list. So say this piece of string was in the beginning and middle of the larger string, both of them would be found, and their index's would be added to the List. and the List would contain 0 and the other index whatever it would be. Ive been playing around, and the string.IndexOf does almost what i'm looking for, and ive written some code. But i cant seem to get it to work: List<int> inst = new List<int>(); int index = 0; while (index < source.LastIndexOf("extract\"(me,i-have lots. of]punctuation", 0) + 39) { int src = source.IndexOf("extract\"(me,i-have lots. of]punctuation", index); inst.Add(src); index = src + 40; } inst = The list source = The large string Any better ideas?

  • Can someone please clarify my understanding of a mock's Verify concept?

    - by Pure.Krome
    Hi folks, I'm playing around with some unit tests and mocking. I'm trying to verify that some code, in my method, has been called. I don't think I understand the Verify part of mocking right, because I can only ever Verify main method .. which is silly because that is what I Act upon anyways. I'm trying to test that my logic is working - so I thought I use Verify to see that certain steps in the method have been reached and enacted upon. Lets use this example to highlight what I am doing wrong. public interface IAuthenticationService { bool Authenticate(string username, string password); SignOut(); } public class FormsAuthenticationService : IAuthenticationService { public bool Authenticate(string username, string password) { var user = _userService.FindSingle(x => x.UserName == username); if (user == null) return false; // Hash their password. var hashedPassword = EncodePassword(password, user.PasswordSalt); if (!hashedPassword.Equals(password, StringComparison.InvariantCulture)) return false; FormsAuthentication.SetAuthCookie(userName, true); return true; } } So now, I wish to verify that EncodePassword was called. FormsAuthentication.SetAuthCookie(..) was called. Now, I don't care about the implimentations of both of those. And more importantly, I do not want to test those methods. That has to be handled elsewhere. What I though I should do is Verify that those methods were called and .. if possible ... an expected result was returned. Is this the correct understanding of what 'Verify' means with mocking? If so, can someone show me how I can do this. Preferable with moq but i'm happy with anything. Cheers :)

  • Architecting a generic search result web control

    - by Bartek Tatkowski
    In a project I'm currently working for we've stumbled upon the need for several kinds of search results presentation controls. The search result are similar, but not identical. For example, in the "office search" result we might want to present the office name and location, while in the "document search" could contain document name, author and publishing date. These fields should be sortable. My current strategy is to employ the Factory pattern and do something like this: ISearchResult officeResults = SearchResultFactory.CreateOfficeSearchResults(data); ISearchResult documentResults = SearchResultFactory.CreateDocumentSearchResults(data); The problem is: I don't know how to implement the markup code. Should I just do Controls.Add(officeResults); in the containing page? Or is there some ASPX trickery to create generic web controls? Or maybe I'm overthinking this and just should create five classes? ;)

  • MasterPage Page_Load hits before Grid_ItemCommand

    - by Raheel Khan
    I am using the session object to store success/error messages based on user actions. On each postback, the message is set on ItemCommend and retrieved on the Page_Load of the master page. Once retrieved, the message is deleted from the session. The problem is that the master page's Page_Load gets called before the ItemCommand gets called so the message does not show up until the next refresh or postback. How is this situation normally handled? Is there some other event we can code against?

  • Override An Existing Property as a Child form of its return type

    - by Jason
    I apologize if that title is confusing. This question may be a result of lack of coffee and/or sleep, but my mind is not working correctly right now. Anyways, I have an inheritance tree like such (I know the architecture isn't ideal): BaseClass GeneralForm : Inherits BaseClass SpecificForm : Inherits GeneralForm And an object like so: MyItem MySpecificItem : Inherits MyItem I have Items As List (Of MyItem) as a property in BaseClass. I would like for SpecificForm to somehow override Items to return type List (Of MySpecificItem). I feel like this is easy to do, but again, my head is spinning and I can't think straight at the moment. Thank you so much in advance.

  • Javascript not registering/executing after button click

    - by rs
    I have a textbox which i convert to tinymce textbox using tinymce.js file. I'm trying to add a new script with database fields substituted based on selection made from dropdownlist to page using registerstartupscript. In page load protected sub page_load(byVal sender as object, byval e as EventArgs) handles me.load AddScriptToPage() if not page.ispostback() then session("fname") = nothing end if end sub Script Method Sub AddScriptToPage() dim _script = " c.onRenderMenu.add(function(c, m) { " & _ add_columns() & _ "}); " ClientScript.RegisterStartupScript(Me.GetType(), keyword,_script) End Sub function add_columns() as string dim ret_string = String.empty select case ddlList.selectedvalue case 1 sqlcommand = "xyz" case 2 sqlcommand = "xyz" case 3 //Load from excel sqlcommand = nothing end select if sqlcommand isnot nothing then executereader() while reader.read() ret_string = ret_string & reader("column") end while elseif session("fname") isnot nothing dt = getdatatable(session("fname").tostring()) //method that opens oledb connection and returns columns for each dr in dt.rows ret_string = ret_string & dr("column") next end if add_columns = ret_string end function When excel file is uploaded to server this event is called protected sub btnclick(byVal sender as object, byval e as EventArgs) if hasfile then 'i have custom properties set after control validation 'Upload file 'set session value with filepath session("fname") = filepath 'call js register event AddScriptToPage() end if end sub When i click upload button i'm calling AddScriptToPage, and debug it it hits AddScripttoPage event and executes it but it doesn't showup on page. It should show column names in tinymce editor but it doesn't. But when i click another button on the same page it shows (becos session has the filename). On Upload button click page flow: Page load - AddScriptToPage is executed (registers scripts with no columns) Then AddScriptToPage in btnclick event is executed (registers scripts with columns) Why is this script not getting registered even though it is executed on vb code on uploadclick event? And why does it show up after another button click and not original button click that calls this event?

  • DropDownList selectedValue not changing display

    - by MemphisDeveloper
    I have a list of controls that I change based on an event. The controls are contained within a table that is created dynamically. I traverse through a set of controls and if it is a RadioButtonList or a DropDownList I do the following: CType(cntrl, ListControl).SelectedValue = val The radio buttons set just fine but the dropdown list doesn't reset. Can anyone tell me why. The initial table is created on the first Page Load and stored in memory. It's values are changed during the eventhandling and reposted to a MasterPage's content holder.

  • Is a Multi-DAL Approach the way to go here?

    - by Krisc
    Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.

  • Validationattribute only when value is changed?

    - by boris callens
    I want to write a custom ValidationAttribute that checks if the given value is unique or not. The problem is that in the edit screen, it is not guaranteed that the user actually changed the value, resulting in a false error. Is there a way to check in my attribute whether the value actually changed? Or can I trigger the attribute only when the value has changed? I'm getting the feeling this requirement maybe just doesn't belong in an attribute?

  • MS Access Bulk Insert exits app

    - by Brij
    In the web service, I have to bulk insert data in MS Access database. First, There was single complex Insert-Select query,There was no error but app exited after inserting some records. I have divided the query to make it simple and using linq to remove complexity of query. now I am inserting records using for loop. there are approx 10000 records. Again, same problem. I put a breakpoint after loop, but No hit. I have used try catch, but no error found. For Each item In lstSelDel Try qry = String.Format("insert into Table(Id,link,file1,file2,pID) values ({0},""{1}"",""{2}"",""{3}"",{4})", item.WebInfoID, item.Links, item.Name, item.pName, pDateID) DAL.ExecN(qry) Catch ex As Exception Throw ex End Try Next Public Shared Function ExecN(ByVal SQL As String) As Integer Dim ret As Integer = -1 Dim nowConString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + System.AppDomain.CurrentDomain.BaseDirectory + "DataBase\\mydatabase.mdb;" Dim nowCon As System.Data.OleDb.OleDbConnection nowCon = New System.Data.OleDb.OleDbConnection(nowConString) Dim cmd As New OleDb.OleDbCommand(SQL, nowCon) nowCon.Open() ret = cmd.ExecuteNonQuery() nowCon.Close() nowCon.Dispose() cmd.Dispose() Return ret End Function After exiting app, I see w3wp.exe uses more than 50% of Memory. Any idea, What is going wrong? Is there any limitation of MS Access?
