Hi Buran,
You can check it in the page_load event of the usercontrol, checking value
for Page.IsPostBack.
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 postbackUC.
/// </summary>
public class postbackUC : System.Web.UI.UserControl
{
private void Page_Load(object sender, System.EventArgs e)
{
if (Page.IsPostBack)
{
Response.Write("This is a PostBack... haahaah");
}
else
{
Response.Write("This is not a PostBack...");
}
}
#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.Load += new System.EventHandler(this.Page_Load);
}
#endregion
}

Thanks for your help. I have another question. How can I detect the
postback IN my user control? I am loading the user control every time the parent
page is posted back, but how can I detect the post back in the user control?

When ever you are loading the usercontrol dynalically, you need to take
care of loading the usercontrol again on the postback event, so if the user
has clicked the cancel button then in that case dont load the usercontrol
that is one of the ways.
other possible way is
// Code for Adding the User Control
PlaceHolder1.Controls.Add(LoadControl("taclient.as cx"));
// Code for Removing the UserControl
Control myControl = PlaceHolder1.Controls[0];
PlaceHolder1.Controls.Remove(myControl);

news:OU**************@tk2msftngp13.phx.gbl... Dear ASP.NET Programmers,
I am loading a web user control ("taclient.ascx") into a placeholder (ID: phFA). The web user control contains a cancel button (ID: btnCancel).
I would like to "unload" the web user control when the user clicks on
the cancel button. How can I accomplish this? Thanks in advance.
dim myControl as Control
myControl = LoadControl("taclient.ascx")
phFA.Controls.Clear()
phFA.Controls.Add(myControl)
