I've been googling all day but I still can't get the button click event on
a dynamic WebUserControl to fire.
I've tried raising events delegates and everything else I can find.
The text in the controls seems to persist okay but no button clicks.
hopefully it's not relevent but I am using a WebApplication under VS2005
Thanks in advance.
here is my basic test code for the WebUserControl:
Code:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="wuc.ascx.vb" Inherits="WebApplication1.wuc" %>
<asp:TextBox ID="TextBox1" runat="server" Width="216px">zzz</asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" />
Code:
Partial Public Class wuc
Inherits System.Web.UI.UserControl
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Public Property txt() As String
Get
Return TextBox1.Text
End Get
Set(ByVal value As String)
TextBox1.Text = value
End Set
End Property
Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' breakpoint here is never reached !
End Sub
End Class
here is my basic test code for the default page:
Code:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebApplication1._Default" %>
<%@ Register Src="wuc.ascx" TagName="wuc" TagPrefix="uc1" %>

</div>
</form>

Code:
Partial Public Class _Default

Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Page.IsPostBack Then
Dim WL As List(Of wuc) = Session("wuclist")

For Each w As wuc In WL

w.EnableViewState = True
w.ID = "wuc" + count.ToString

Panel1.Controls.Add(w)
Next
Else

End Sub
