'Alo

my repeater:

Code:

<asp:Repeater ID="rpProjectList" runat="server" OnItemDataBound="rpProjectList_OnItemDataBound">
                        <ItemTemplate>
                            <tr>
                                <td><asp:TextBox ID="txtName" Text='<%#Eval("Name")%>' runat="server"></asp:TextBox></td>
                                <td><asp:TextBox ID="txtProjectNumber" Text='<%#Eval("ProjectNumber")%>' runat="server"></asp:TextBox></td>
                                <td><asp:TextBox ID="txtDecription" Text='<%#Eval("Description")%>' runat="server"></asp:TextBox></td>
                                <td><asp:Label ID="lblCreatedBy" runat="server" Text='<%#Eval("CreatedBy")%>'></asp:Label> <asp:Label ID="lblCreatedDate" runat="server" Text='<%#Eval("TheDate")%>'></asp:Label></td>
                                <td><asp:Label ID="lblEditedBy" runat="server" /> <asp:Label ID="lblEditedDate" runat="server" /></td>
                                <td><asp:Button ID="btnDelete" runat="server" Text="Delete" /></td>
                            </tr>
                        </ItemTemplate>
                    </asp:Repeater>

Now I tried to write a sub for the click event of btnDelete, but i get errors saying thats there's more than one instance of btnDelete, in my repeater obviously?

so how does one go about pulling it off, and at the same time how do i pass it
the idkey of the record I want to delete, cuz if i use a HiddenField, I get the same error, more than one, blah blah blah

In your repeater include OnItemCommand and on your button include CommandName and CommandArgument

Code:

<asp:Repeater ID="rpProjectList" runat="server" OnItemDataBound="rpProjectList_OnItemDataBound" OnItemCommand="rpProjectList_OnItemCommand" />
 
<asp:button id="btnDelete" runat="server" Text="Delete" CommandName="Delete" CommandArgument='<%#Eval("Idkey")%>' />

Then in your routine:-

Code:

sub rpProjectList_OnItemCommand(ByVal s As Object, ByVal e As RepeaterItemEventArgs)
If e.CommandName="Delete" then
'Delete record with id e.CommandArgument
 
End Sub

Hope that helps.

I had to change it to this to get rid of the errors:

Code:

Sub rpProjectList_OnItemCommand(ByVal s As Object, ByVal e As RepeaterItemEventArgs)
        Dim btnDelete As String = e.Item.FindControl("btnDelete").ToString
        If btnDelete = "Delete" Then
            Response.Write(btnDelete)
        End If
    End Sub

but getting this error:

Code:

Where have i gone wrong

jmurrayhead · #5 July 11th, 2008, 09:08 AM

Shem, that's all wrong..

It should be like this:

Code:

Sub rpProjectList_OnItemCommand(ByVal s As Object, ByVal e As 
RepeaterCommandEventArgs)
    If e.CommandArgument = "delete" Then
        'Do something...
    End If
End Sub

You then have to set the command buttons CommandArgument property equal to delete so the above code works.

richyrich · #6 July 11th, 2008, 09:14 AM

Sorry, my bad....I hadn't realised you'd posted again...I thought it was working...

Shem, J is correct...It should have been e As RepeaterCommandEventArgs

But I then think it should be if e.CommandName="delete" then and the CommandArgument should be your Idkey.

I'm sure that should work...

jmurrayhead · #7 July 11th, 2008, 09:15 AM

Yeap, RR is right. I wasn't paying attention to what I was doing. CommandName would tell us the action to perform and the CommandArgument tells us what record to peform it on.

thanks guys

Hi

unfortunately nothing works, inside the IF statement I put a response.write
and nothing writes to the screen

any ideas on why?

Shem;
Resposne.Write is probably not the best way to debug ASP.NET code. Can you set a breakpoint on the first statement in the event handler (you ARE using something like VWD or VS, right)? If you BP hits, you know the event handler is being fired, and you can example the e variable and ensure it has what you think it has. The code posted here (as corrected) should work. Also, post-up what you have now for a lookie.
