I have a required field validation control on a modal popup. There is also a valdation group on the popup. When I Hit insert button, the popup closes and the validation messsage is lost. I assume that I need to do another Show( ) to keep the window open,
but how will it know that the validation failed?
On the click of the button
if (Page.IsValid == false)
{
RequiredFieldValidator distvalid = (RequiredFieldValidator)FormView1.FindControl("distvalid");
TextBox tbDistance = (TextBox)FormView1.FindControl("tbDistance");
distvalid.ControlToValidate = tbDistance.ToString();
pnlAdd_ModalPopupExtender.Show();
}
on:
