Adding buttons to a datagrid doesn't fire its events

[Andrés Giraldo]

Hi!

I'm adding an asp button to a datagrid on the ItemDataBound event, when
the user clicks on this button, I basically remove the button and create
other 2 buttons... my problem is.. the 2 last buttons doesn't fire his
events... what I'm doing wrong?

Thanks!


Private Sub dtgTest_ItemDat aBound(ByVal sender As Object, ByVal e As
System.Web.UI.W ebControls.Data GridItemEventAr gs) Handles
dtgTest.ItemDat aBound
Dim itemType As ListItemType = e.Item.ItemType
Dim btnEdit As New Button

If ((itemType = ListItemType.Pa ger) Or (itemType =
ListItemType.He ader) Or (itemType = ListItemType.Fo oter)) Then
Return
Else
btnEdit.Style.I tem("BACKGROUND-IMAGE") =
"url(http://localhost/Images/Edit.gif)"
btnEdit.Style.I tem("BACKGROUND-REPEAT") = "no-repeat"
btnEdit.Width = Unit.Pixel(23)
btnEdit.ID = "btnEdit" & e.Item.DataSetI ndex

AddHandler btnEditar.Click , AddressOf Edit

e.Item.Cells(4) .Controls.Add(b tnEdit)
End If
End Sub

Private Sub Edit(ByVal sender As System.Object, ByVal e As

Dim strIDButton As String
