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_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
dtgTest.ItemDataBound
Dim itemType As ListItemType = e.Item.ItemType
Dim btnEdit As New Button

If ((itemType = ListItemType.Pager) Or (itemType =
ListItemType.Header) Or (itemType = ListItemType.Footer)) Then
Return
Else
btnEdit.Style.Item("BACKGROUND-IMAGE") =
"url(http://localhost/Images/Edit.gif)"
btnEdit.Style.Item("BACKGROUND-REPEAT") = "no-repeat"
btnEdit.Width = Unit.Pixel(23)
btnEdit.ID = "btnEdit" & e.Item.DataSetIndex

AddHandler btnEditar.Click, AddressOf Edit

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

Private Sub Edit(ByVal sender As System.Object, ByVal e As
System.EventArgs)
Dim strIDButton As String
Dim index As Integer
Dim btnCancel As New Button
Dim btnSave As New Button

strIDButton = CType(sender, Button).ID

index = Val(Mid(strIDButton, Len("btnEdit") + 1,
Len(strIDButton)))

dtgTest.EditItemIndex = index

dtgTest.DataSource = Session("_DataView")
dtgTest.DataBind()

'I try to remove its event handlers before removing the button,
but id doesn't work either
RemoveHandler CType(dtgTest.Items(index).Cells(4).Controls(0),
Button).Click, AddressOf Edit

dtgTest.Items(index).Cells(4).Controls.RemoveAt(0)

' This events are not called... why????
