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
}
