is it a internet application ? The timer should be in the client side and the request has to come from timer in client.

Thank u its working fine , i need to display every time 10 records only i need to go up to 100.

for (i = j; i < ds.Tables["AVI_ICAOCodeList"].Rows.Count; i++)
{
j = j + 1;

Session["iterat"] = i + 1;
if (i == 10)
{

Timer1.Enabled = true;

break;

}
