Hi,
I understand that your webform takes long time to complete the postback and
you want the button caused the postback gets disabled after clicked, right?
I think you can use following code as an example:
----8<---- web form ----
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" %>
<!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>Untitled Page</title>
<script type="text/javascript" language="javascript">
function mypostback()
{
form1.button1.disabled = true;
form1.submit();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="button1" runat="server"
OnClientClick="mypostback();" Text="Submit" />
</div>
</form>
</body>
</html>
----8<---- code behind -----
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
System.Threading.Thread.Sleep(3000);
}
}
}
I hope this helps. Please feel free to post here if anything is unclear.
Sincerely,
