Hi ITkid,


are you sure you have added this line exectly as it said:
l.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this item?');")

Show how you are calling the confirmation.

If it is javascript confirmation you have to use the return statement. For example

<a href="link.aspx" onClick="return confirm('Are you sure you want to remove this item?')">delete</a>

This way the link.aspx will only be executed after you click OK in the dialog. So, what does your code look like?

I just used the exact same code in my app.  I found an omission in the builder.com code you referenced.  Add the CommandName attribute to the linkbutton.
<asp:linkbutton id="cmdDel" runat="Server" CommandName="SelectDelete" </asp:linkbutton>

Now in your sub:
Sub DataGrid1_ItemCommand(ByVal s As Object, ByVal e As DataGridCommandEventArgs)
    Select Case e.CommandName
        Case "SelectDelete"
             'Delete the record code goes here (his Listing E)
    End Select
End Sub

It works great for me.  If the user clicks on "OK" of the confirm box it will call this sub.  If the user clicks on cancel, nothing should happen.  (This sub will NOT be called)
Hope this clarifys it.

Oops I forgot, you will also need the following in the <asp:Datagrid > statement
<asp:DataGrid1  OnItemCommand="DataGrid1_ItemCommand"/>
