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

}

HTH
