Adding "Delete Confirmation" in DetailsView for .NET 2.0

Could anyone tell me how to put delete confirmation pop up in detailsview control?  (in VB.NET)

I created 3 button ( Edit, Delete, New) as commandfield. I tried with <asp:templatefield> and it works but I would like implement in <asp:commandfield>.

Thanks in advance.
 
 <asp:CommandField ButtonType="Button" ShowDeleteButton="True" ShowEditButton="True"    ShowInsertButton="True" />
'I would like to implement on above line.

<%--        <asp:TemplateField>
        <ItemTemplate>
        <asp:LinkButton
        Text="Delete" runat="server" Commandname="delete"  OnClientClick="return confirm('Delete?');">
        </asp:LinkButton>
        </ItemTemplate>
        </asp:TemplateField>--%>

you can add the onclick attribute in the code behind for the page on the RowDataBound event.

example  (bear in mind index for cells depends in which colum you have the command button )
If e.Row.RowType = DataControlRowType.DataRow Then
   Dim lb As LinkButton
   lb = e.Row.Cells(0).Controls(0)
   lb.Attributes.Add("onclick", "return confirm('Delete?');")
End If
or c#
if ( e.Row.RowType == DataControlRowType.DataRow  )
{
    LinkButton lb =(LinkButton) e.Row.Cells[0].Controls[0] as LinkButton
   if ( lb != null )
  {
      lb.Attributes.Add("onclick", "return confirm('Delete?');")
  }

Ahh.. the code you gave doesnt seem to work for DetailsView... or maybe I'm just not experienced enough :(

After surfing for hours I've found a solution in C#... however I need it in VB because my C skills are non-existent. Do you know the VB equivalent for:

--------------------------------------------------------------------------------------------
protected void DetailsView1_ItemCreated(object sender, EventArgs e)
{
   // Test FooterRow to make sure all rows have been created
   if (DetailsView1.FooterRow != null)
   {
     // The command bar is the last element in the Rows collection
     int commandRowIndex = DetailsView1.Rows.Count-1;
     DetailsViewRow commandRow = DetailsView1.Rows[commandRowIndex];
     
     // Look for the DELETE button
     DataControlFieldCell cell = (DataControlFieldCell) commandRow.Controls[0];
     foreach(Control ctl in cell.Controls)
     {
       LinkButton link = ctl as LinkButton;
       if (link != null)
       {
          if (link.CommandName == "Delete")
          {
             link.ToolTip = "Click here to delete";
             link.OnClientClick = "return confirm('Do you really want to delete this record?');";
          }
       }
    }
}
--------------------------------------------------------------------------------------------

That would help heaps!
mm my vb skills are not that good, more of a c# person. but here goes
If DetailsView1.FooterRow != null Then
  Dim  commandRowIndex as Integer = DetailsView1.Rows.Count - 1
  Dim commandRow as DetalsViewRow = CType( DetailsView1.Rows( commandRowIndex ), DetailsViewRow)
  Dim cell as DataControlFieldCell  = CType( commandRow.Controls(0), DataControlFieldCell  )
  For Each ctl As Control In cell.Controls
      Dim lnk as LinkButton = CType( ctl, LinkButton )
      if lnk != null then
          If lnk.CommandName = "Delete" Then
              lnk.OnClientClick = " return confirm( 'Delete?' ); "
          End If
       End If
   Next
End If
in case the !=  doesnt work ( not equal ) then use <> 

ps a good compairson site for vb.net versus c# is
