Linkbutton in User Control Not Working

[Anthony Hunter]

Hello,

I am loading a user control into a panel on my default page "Default.aspx" :

void LoadControlData()
{
this.pnlCONTENT.Controls.Add(LoadControl("Default_Content.ascx"));
}

The user control "Default_Content.ascx" has a linkbutton that is tied to a
click event:

void lnkMainPage_Click(object sender, EventArgs e)
{
Response.Redirect(User_Info.Application_Path + "\\Main.aspx");
}

When I click the link button, the event never gets executed (tested in CLR
Debugger). I am only redirected back to default.aspx with nothing on the
page. Is there something I may be missing?

Please help... Thanks in advance,

Tony

Hi Tony,

You may already have checked, but be sure there's an event handler for your
linkbutton. Here's how mine user control looked:

namespace p4320workcs
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

/// <summary>
/// Summary description for Default_Content.
/// </summary>
public class Default_Content : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.LinkButton lnkMainPage;

private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
}

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
base.OnInit(e);
}

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.lnkMainPage.Click += new
System.EventHandler(this.lnkMainPage_Click);
this.Load += new System.EventHandler(this.Page_Load);

}
#endregion

private void lnkMainPage_Click(object sender, System.EventArgs e)
{
Response.Redirect("Main.aspx");
}
}
}

Are you creating that LinkButton staticly inside the ASPX page or dynamicly
inside the CS/VB file (is any part dynamic about this linkbutton)? If the
second one is in question, the answer is clear: You are recreating that link
button too late or with different state.

If the first one is the question, I would check the RUNAT=SERVER attribute
and subscription to event statement inside your code.

The link button is added as a static control on the ascx web form. Here is
the html:

<asp:LinkButton id="lnkMainPage" onclick="lnkMainPage_Click"
Font-Underline="True" Runat="server" CssClass="clsASPLink">Main
Page</asp:LinkButton>

This appears to be a big problem.

I finally decided to add my user control to the page by registering it and
adding an html tag for it. Doing it this way, the link button works fine.
I then decided to add the user control programmatically using a placeholder
and loadcontrol(), this too will add the control to the page; but I have the
same problem as before when I added the user control to a panel...the link
does not work. I am using web matrix 0.6.812.0 as my development tool -
what is up with this?

Any help will be greatly appreciated.
