  • ASP.NET ObjectDataSource, change CommandName property of FromView Button

    - by Tone
    I have an ObjectDataSource that I'm using with a FormView, and it works fine, but i want to change one small thing. On the FormView the button that fires the update has the CommandName attribute set to "Update," but I would like to change that attribute to something other than "Update" - when I do change that attribute the update no longer works. The reason I want to do this is I have multiple FormViews on the same page and need to have multiple update buttons. Below is my code: FormView: <asp:FormView ID="fvGeneralInfo" runat="server" DataSourceID="objInstructorDetails" CssClass="Gridview" OnItemCommand="fvGeneralInfo_ItemCommand" DefaultMode="Edit"> <EditItemTemplate> <table> .... <tr> <td style="text-align:right;"> <asp:Label runat="server" ID="lblGeneralInfoMessage" Text="General Info updated successfully" Visible="false" /> </td> <td> <asp:Button runat="server" ID="btnUpdateGeneralInfo" ValidationGroup="UpdateGeneralInfo" Text="Update" CommandName="Update" /> <asp:Button runat="server" ID="btnCancelGeneralInfo" Text="Cancel" CommandName="CancelGeneralInfo" /> </td> </tr> </table> </EditItemTemplate> </asp:FormView> ObjectDataSource: <asp:ObjectDataSource ID="objInstructorDetails" runat="server" TypeName="AIMLibrary.BLL.Instructor" SelectMethod="GetInstructorDetails" InsertMethod="InsertInstructor" UpdateMethod="UpdateInstructor" OnInserting="objInstructorDetails_OnInserting" OnUpdating="objInstructorDetails_OnUpdating" > <SelectParameters> <asp:QueryStringParameter Name="InstructorId" QueryStringField="InstructorId" /> </SelectParameters> <UpdateParameters> <asp:Parameter Name="instructorId" Type="Int32" /> <asp:Parameter Name="firstName" Type="String" DefaultValue="" /> <asp:Parameter Name="middleName" Type="String" DefaultValue="" /> <asp:Parameter Name="lastName" Type="String" DefaultValue="" /> <asp:Parameter Name="phone" Type="String" DefaultValue="" /> <asp:Parameter Name="email" Type="String" DefaultValue="" /> <asp:Parameter Name="addressLine1" Type="String" DefaultValue="" /> <asp:Parameter Name="addressLine2" Type="String" DefaultValue="" /> <asp:Parameter Name="city" Type="String" DefaultValue="" /> <asp:Parameter Name="state" Type="String" DefaultValue="" /> <asp:Parameter Name="zip" Type="String" DefaultValue="" /> <asp:Parameter Name="abcBoardNumber" Type="String" DefaultValue="" /> </UpdateParameters> </asp:ObjectDataSource>

  • ASP.NET catching controls from html generated from the database

    - by Drahcir
    I have a set of websites that basically do the exact same thing in terms of functionality, the only thing that varies is the css and how the html is laid out. Is there a way to generate the html from a database (ie retreiving the html from a table) and then catching the controls (like buttons, textboxes etc) from the code behind? UPDATE: Here is an example of what I want to acheive: <html> <div id="generatedContent" runat="server"> <!-- the following content has been generated from the database on the page load event --> <div> This is a textbox <input id="tb1" runat="server" type="text" /> This is a button <input type="submit" id="btn1" runat="server" value="My Button" /> </div> </div> </html> This is the code behind var tb1 = new HtmlControls.HtmlInputText(); tb1 = FindControl("tb1"); var btn1 = new New HtmlControls.HtmlInputSubmit(); btn1 = FindControl("btn1"); Now obviously since the html has been generated from the database (ie after the page has already been initialised) the FindControl method will return null.

  • .NET values lookup

    - by Maciej
    Hi, I have a feeling of missing something obvious. UDP receiver application. It holds a collection of valid UDP sender IPs - only guys with IP on that list will be considered. Since that list must be looked at on every packet and UDPs are so volatile, that operation must be maximum fast. Good choice is Dictionary but it is a key-value structure and what I actually need here is a dictionary-like (hash lookup) key only structure. Is there something like that? Small annoyance rather than a bug but still. I can still use Dictionary Thanks, M.

  • Extending the .NET type system so the compiler enforces semantic meaning of primitive values in cert

    - by Drew Noakes
    I'm working with geometry a bit at the moment and am converting a lot between degrees and radians. Unfortunately, both of these are represented by double, so there's compile time warning/error if I try to pass a value in degrees where radians are expected. I believe F# has a compile-time solution for this (called units of measure.) I'd like to do something similar in C#. As another example, imagine a SQL library that accepts various query parameters as strings. It'd be good to have a way of enforcing that only clean strings were allowed to be passed in at runtime, and the only way to get a clean string was to pass through some SQL injection attack preventing logic. The obvious solution is to wrap the double/string/whatever in a new type to give it the type information the compiler needs. I'm curious if anyone has an alternative solution. If you do think wrapping is the only/best way, then please go into some of the downsides of the pattern (and any upsides I haven't mentioned too.) I'm especially concerned about the performance of abstracted primitive numeric types on my calculations at runtime.

  • Why no ArgumentEmptyException in .NET ?

    - by Andrei Rinea
    I am beginning to think I am doing something wrong. I mean they did place System.String.IsNullOrWhitespace finally but no ArgumentEmptyException class. public FilterItem(string name, IEnumerable<string> extensions) { if (string.IsNullOrWhiteSpace(name)) { throw new ArgumentNullException("name"); } if (extensions == null) { throw new ArgumentNullException("extensions"); } if (extensions.Count() == 0) { throw new ArgumentOutOfRangeException("extensions"); } this.Name = name; this.Extensions = extensions; } throwing an ArgumentOutOfRangeException feels unnatural. Also an instance of ArgumentException is too general in my opinion. It's easy to me to create a new exception class call it this way and have it over with. What bugs me is that it's not in the BCL/FCL and I am beginning to think there's a good reason not to have it. Should there be one?

  • Please Explain .NET Delegates

    - by user275561
    So I read MSDN and Stack Overflow. I understand what the Action Delegate does in general but it is not clicking no matter how many examples I do. In general, the same goes for the idea of delegates. So here is my question. When you have a function like this: public GetCustomers(Action<IEnumerable<Customer>,Exception> callBack) { } What is this, and what should I pass to it?

A.AddMethod(methodname,x = MyStaticClass.DoAction(x)); Thanks

  • ASP.Net repeater item.DataItem is null

    - by mattgcon
    Within a webpage, upon loading, I fill a dataset with two table with a relation between those tables and then load the data into a repeater with a nested repeater. This can also occur after the user clicks on a button. The data gets loaded from a SQL database and the repeater datasource is set to the dataset after a postback. However, when ItemDataBound occurs the Item.Dataitem is always null. Why would this occur? below is my HTML repeater code <asp:Repeater ID="rptCustomSpaList" runat="server" onitemdatabound="rptCustomSpaList_ItemDataBound"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <table> <tr> <td> <asp:Label ID="Label3" runat="server" Text="Spa Series:"></asp:Label> </td> <td> <asp:Label ID="Label4" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "SPASERIESVALUE") %>'></asp:Label> </td> </tr> <tr> <td> <asp:Label ID="Label5" runat="server" Text="Spa Model:"></asp:Label> </td> <td> <asp:Label ID="Label6" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "SPAMODELVALUE") %>'></asp:Label> </td> </tr> <tr> <td> <asp:Label ID="Label9" runat="server" Text="Acrylic Color:"></asp:Label> </td> <td> <asp:Label ID="Label10" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "ACRYLICCOLORVALUE") %>'></asp:Label> </td> </tr> <tr> <td> <asp:Label ID="Label11" runat="server" Text="Cabinet Color:"></asp:Label> </td> <td> <asp:Label ID="Label12" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "CABPANCOLORVALUE") %>'></asp:Label> </td> </tr> <tr> <td> <asp:Label ID="Label17" runat="server" Text="Cabinet Type:"></asp:Label> </td> <td> <asp:Label ID="Label18" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "CABINETVALUE") %>'></asp:Label> </td> </tr> <tr> <td> <asp:Label ID="Label13" runat="server" Text="Cover Color:"></asp:Label> </td> <td> <asp:Label ID="Label14" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "COVERCOLORVALUE") %>'></asp:Label> </td> </tr> </table> <asp:Label ID="Label15" runat="server" Text="Options:"></asp:Label> <asp:Repeater ID="rptCustomSpaItem" runat="server"> <HeaderTemplate> <table> </HeaderTemplate> <ItemTemplate> <tr> <td> <asp:Label ID="Label1" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "PROPERTY") %>'></asp:Label> </td> <td> <asp:Label ID="Label2" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "VALUE") %>'></asp:Label> </td> </tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> <table> <tr> <td style="padding-top:15px;padding-bottom:30px;"> <asp:Label ID="Label7" runat="server" Text="Configured Price:"></asp:Label> </td> <td style="padding-top:15px;padding-bottom:30px;"> <asp:Label ID="Label8" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "SPAVALUEVALUE") %>'></asp:Label> </td> </tr> </table> <asp:Label ID="Label16" runat="server" Text="------"></asp:Label> </ItemTemplate> <FooterTemplate></FooterTemplate> </asp:Repeater>

  • Excel 2010 64 bit can't create .net object

    - by aboes81
    I have a simple class library that I use in Excel. Here is a simplification of my class... using System; using System.Runtime.InteropServices; namespace SimpleLibrary { [ComVisible(true)] public interface ISixGenerator { int Six(); } public class SixGenerator : ISixGenerator { public int Six() { return 6; } } } In Excel 2007 I would create a macro enabled workbook and add a module with the following code: Public Function GetSix() Dim lib As SimpleLibrary.SixGenerator lib = New SimpleLibrary.SixGenerator Six = lib.Six End Function Then in Excel I could call the function GetSix() and it would return six. This no longer works in Excel 2010 64bit. I get a Run-time error '429': ActiveX component can't create object. I tried changing the platform target to x64 instead of Any CPU but then my code wouldn't compile unless I unchecked the Register for COM interop option, doing so makes it so my macro enable workbook cannot see SimpleLibrary.dll as it is no longer regsitered. Any ideas how I can use my library with Excel 2010 64 bit?

  • Set Custom ASP.NET UserControl variables when its in a Repeater

I thought I should be able to find uc by looking in the e.Item and then setting it somehow. I think this is the part where I'm missing something. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes["ParentItemID"] = i.ItemID.ToString(); } Any thoughts would be appreciated. Also tried this with similar results... when I debug inside my usercontrol (pfd1) the parameters I am trying to set have not been set. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes.Add("ContainerID", _cid.ToString()); uc.Attributes.Add("ParentItemId", i.ItemID.ToString()); }
