Dynamic linkbutton handling

[cjdrake]

My page creates linkbuttons dynamically and adds them to a table in the top row. When a user clicks on one of these i need to change the content in the table.

The problem i am having is that page_load is being called before the button handler method, thus the table is always a step behind where it should be.

Any advice on how to remedy/workaround this problem would be greatly appreciated. Thankyou.
Code snippet:

*************
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

If Not IsPostBack() Then
Viewstate("buttonClicked") = Application("buttonNames")(0)
End If

Dim table As New Table
table = setTable(CType(ViewState("buttonClicked"), String))
PlaceHolder1.Controls.Add(table)

End Sub

Sub Button_Handler(ByVal sender As Object, ByVal e As CommandEventArgs)

Viewstate("buttonClicked") = e.CommandArgument

End Sub
*************

This should be placed on ASP.NET forum, but since you are here i can give a simple example

Private Sub btnCustom_Click(ByVal sender As System.Object, ByVal e As EventArgs)
  Response.Write("Buton Clicked: " + sender.ID)
'do action based on the ID property
End Sub

'somewere in the page load
Dim btn1 As New Button()
AddHandler btn1.Click, AddressOf btnCustom_Click
btn1.ID="Button 1"

Dim btn2 As New Button()
AddHandler btn2.Click, AddressOf btnCustom_Click
btn2.ID="Button 2"

Dim tRow As New TableRow()
Dim tCell As New TableCell()

tCell.Controls.Add(btn1)
tRow.Cells.Add(tCell)

tCell=New TableCell()
tCell.Controls.Add(btn2)
tRow.Cells.Add(tCell)

myTableID.Rows.Add(tRow)

This should be the main code.

Thanks for replying- sorry I posted in the wrong forum. I tried your example out and it works well, but I it's not really a solution to my problem.

Imagine a third cell with some text in, spanning underneath the 2 cells you created. When a button is clicked, this is the text I wish to change.... i've tried all sorts of solutions including trying to create the table in the button clicked method but nothing is working.
(sorry if i'm being stupid- i'm new to ASP.net)
Thanks in advance.

        'in load
        Dim btn1 As New LinkButton
        AddHandler btn1.Click, AddressOf btnCustom_Click
        btn1.Text = "Button 1"
        btn1.ID = "Button 1"

        Dim btn2 As New LinkButton
        AddHandler btn2.Click, AddressOf btnCustom_Click
        btn2.Text = "Button2"
        btn2.ID = "Button 2"

        Dim tRow As New TableRow
        Dim tCell As New TableCell

        tCell.Controls.Add(btn1)
        tRow.Cells.Add(tCell)

        tCell = New TableCell
        tCell.Controls.Add(btn2)
        tRow.Cells.Add(tCell)

        Table1.Rows.Add(tRow)

        tRow = New TableRow
        tCell = New TableCell

        tCell.Text = "Not clicked anything yet"
        tCell.ColumnSpan = 2
        tRow.Cells.Add(tCell)

        Table1.Rows.Add(tRow)

Private Sub btnCustom_Click(ByVal sender As System.Object, ByVal e As EventArgs)
  'set 3rd cell to:("Button Clicked: " + sender.ID)
End Sub
