0	Hi friend, You use try, catch statement to handle the exception. protected void Page_Load(object sender, EventArgs e) { CustId = string.Empty; if (!Page.IsPostBack) { try { if (Request.QueryString != null) { CustId = Request.QueryString["Id"].ToString(); } if (chkContactDetails.SelectedIndex != -1) { GetContactDetails(CustId); } } catch { } } } With regards, J.Prabu.

Hi friend,
You use try, catch statement to handle the exception.

protected void Page_Load(object sender, EventArgs e)
{
CustId = string.Empty;
if (!Page.IsPostBack)
{
try
{
if (Request.QueryString != null)
{
CustId = Request.QueryString["Id"].ToString();
}
if (chkContactDetails.SelectedIndex != -1)
{
GetContactDetails(CustId);
}
}
catch
{
}
}
}
