Hi, please help me out!

my code is

C#

protected void Page_Load(object sender, EventArgs e)
    {
        int Count1= GrvNewPORequests.Rows.Count;
        
        if (!IsPostBack)
        {
            txtPODate_CalendarExtender.StartDate = DateTime.Today;
            txtReqDate_CalendarExtender.StartDate = DateTime.Today;
            
            BindGridNewPOReq();
            int count = GrvNewPORequests.Rows.Count;
            // first time the count will show the no of rows and same will display on the page
        }
       // Second time Coiunt1 will show '0' !
    }

The same code is working fine where the master page is different!
