Actually I am getting thisbut without entering any Id/Name in textbox I am getting all records of particular Table when I click ImageButton. How to restrict that ImageButton in order to get records only when I select from TextBox.

two ways you can restrict one client side one is server side server side. protected void imgButton_Click(object sender ImageClickEventArgs e) { if(!string.IsNullOrEmpty(txtName.Text.Trim())) { //here call you bind grid method } } client side--- function IsNameBlank() { var txtName = document.getElementById( ).value; if (txtName.trim() == ) return false; return true; }
