Hi,
I found some posts on this but couldn't figure out if this is solution is possible from what I found. I have a page that will load from 1 to many user controls depending on a user's settings. The control I am having problems with has a callbackPanel in it and I'd like the user to be able to click a button and reload that content in the control. Since the userControl is loaded dynamically, It appears that the page can't find that control again to handle the callback. Is this possible? Here is a very simple example of what I'm trying to do:
Default6.aspx
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default6.aspx.vb" Inherits="Default6" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Panel ID="pnlControl" runat="server" />
</div>
</form>
</body>
</html>
Default6.aspx.vb
Partial Class Default6
Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
Dim ttControl As UserControl = LoadControl("~/ttcontrols/eoSample.ascx")
pnlControl.Controls.Add(ttControl)
End If
End Sub
End Class
ttControls/eoSample.aspx
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="eoSample.ascx.vb" Inherits="ttcontrols_eoSample" %>
<%@ Register TagPrefix="eo" Namespace="EO.Web" Assembly="EO.Web" %>
<eo:CallbackPanel ID="cpTest" runat="server" LoadingHTML="Loading" Triggers="{ControlID:btnTest;Parameter:test}">
<asp:Button ID="btnTest" runat="server" Text="Save" /><br /><br />
<asp:Label ID="lblClicked" runat="server" Text="" />
</eo:CallbackPanel>
ttControls/eoSample.aspx.vb
Partial Class ttcontrols_eoSample
Inherits System.Web.UI.UserControl
Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
End If
End Sub
Sub btnTest_Clicked(ByVal sender As Object, ByVal e As EventArgs)
lblClicked.Text = Now()
End Sub
End Class
Thanks for any information you can provide.
