[Resolved] OnEditCommand Not Firing in DataList

Hello,

I had a page that I coded in Dreamweaver, before i was convinced to start using VS.NET IDE... Well, I had a DataList that had a button in the itemtemplate. every time the button was clicked, i had the EditCommand Event fire for the Datalist, and from there did what i needed to do..

Now i'm converting this page to using codebehind, and i'm using VisualStudio.NET to code in. I can't seem to get the EditCommand Event to fire for the life of me.

Here is my HTML for the DataList:

VB Code:

<table width="500" align="center" border="0" cellpadding="0" cellspacing="0">
    <asp:DataList HeaderStyle-HorizontalAlign="center" id="dlZipCodes" runat="server" Width="500" Height="80">
        <HeaderTemplate>
            <tr>
                <td><strong><font size="2" face="Verdana">Expires:</font></strong><font size="2" face="Verdana">&nbsp;</font></td>
                <td><font size="2" face="Verdana"><strong>Visible:</strong></font></td>
                <td><font size="2" face="Verdana"><strong>Zip Code:</strong></font></td>
                <td>&nbsp;</td>
            </tr>
        </HeaderTemplate>
        <ItemTemplate>
            <tr>
                <td><%# Convert.ToDateTime(Container.DataItem("Expires")).ToShortDateString %></td>
                <td>
                    <asp:CheckBox ID="chkZIP_Visible" Runat="server" Text="" Checked='<%# Container.DataItem("Visible") %>' />
                </td>
                <td>
                    <asp:DropDownList Runat="server" ID="lstZipCodes"></asp:DropDownList>
                </td>
                <td>
                    <asp:Button CommandName="edit" Runat="server" Text="Update" />
                    <asp:Label Runat="server" ID="lblZIP_ID" Visible="True" Text='<%# Container.DataItem("ID") %>' />
                    <asp:Label Runat="server" ID="lblZIP_Zip" Visible="True" text='<%# Container.DataItem("ZipCode") %>' />
                </td>
            </tr>
        </ItemTemplate>
    </asp:DataList>
</table>

Here's the Event Code in my CodeBehind:

VB Code:

Private Sub dlZipCodes_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dlZipCodes.EditCommand
 
          'My Code Here
           Dim objFile As System.IO.TextWriter
           objFile = IO.File.CreateText("F:\Out.txt")
           objFile.WriteLine("UPDATE ZipCodes SET ZipCode = '" & strZip & "', Visible = " & intVisible & " WHERE ID = " & intID)
           objFile.Close()
 
End Sub

I can't figure out what is going wrong.. the event never fires (i've stuck in some code in the sub that writes to a textfile, but the text file remains empty to no avail :/..

Anyways, i'm sure there's something small that i'm missing, i just can't figure out what... thanks for the help guys!

You are missing the page directives for the .aspx file. The directives tell the name and locaction of the code-behind file, as well as other information.

nope, that's not the problem...

All the other subs in the code-behind file work just fine... i know for sure that the right code-behind file is being targetted...

any other ideas?

Well,

After About 3 Hours, i finally got it working... There was something tricky going on to do with PostBacks. Apparently the Event that wasn't fired fires on the postback (i did not know this), and so since i had some code to populate that datagrid that was firing every page load, the EditCommand event was not firing...

Solution: I simply moved that code that was binding the datalist on every page load so that it fired only on Non-PostBacks...

Works now! Phew!
