Events on my page

[Steven ONeil]

I'm trying to process the Onclick event of my page but it's never working. The button is dynamical added to the sites MainPanel.

If I click the button on the page the Page_Load Event() is processed during the postback but not the Sub Button_Click.

Where is my mistake

Thanks for hints and ideas
Steve

Here is my example code

Public Class WebForm
Inherits System.Web.UI.Pag

#Region " Web Form Designer Generated Code

'This call is required by the Web Form Designer
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent(

End Su
Protected WithEvents MainPanel As System.Web.UI.WebControls.Pane

'NOTE: The following placeholder declaration is required by the Web Form Designer
'Do not delete or move it
Private designerPlaceholderDeclaration As System.Objec

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Ini
'CODEGEN: This method call is required by the Web Form Designe
'Do not modify it using the code editor
InitializeComponent(
End Su

#End Regio

Protected WithEvents Button As New System.Web.UI.WebControls.Butto

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

If Not IsPostBack The
Design_Page(
End I

End Su

Private Sub Design_Page(

Button.ID = "Button
Button.Style.Add("position", "absolute"
Button.Width = Unit.Pixel(30
Button.Height = Unit.Pixel(30

MainPanel.Controls.Add(Button

End Su

Private Sub Button_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles
Button.Clic
End Su

End Class

Just looking over it quickly, you may be running into a problem using
"button" as your button's id. .net can get confused when you start naming
your objects the same as its objects. I would avoid doing that for your
sanity :)

Hi Michael,

I tried removing the ID but that does not help. After postback the Page_Load() event is processed but not the Button_Click() sub.....

You have to recreate the button every time the page loads.

Http is stateless - the page is recreated from scratch every time. If the
second time there is no button - there is no event to run for a button that
doesn't exist.

Don't remove the ID, just rename it from "Button" to something like
"btnClick". You'll also have to change your handlers as well to update the
change.

[bruce barker]

you need to add the button (call your designpage) on postback also, for it
to be initialized. the button actually fires the onclick, so it need to be
initialized. also its a good practice to add dynamic controls at page init
rather than page load, so that they can retrieve their postback values.

try:

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
InitializeComponent()
Design_Page()
End Sub

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