I have a rad grid in which I want to do a custom validation at the time of adding or editing. But the custom validator server side code is not firing. Any kind of suggestion or help would be appreciated. Please find my code below.

Code for Custom validator.

protected void ServerValidate(object sender, ServerValidateEventArgs args)

{

CustomValidator custValidator = (CustomValidator)sender;

GridEditableItem eventargs = (GridEditableItem)custValidator.NamingContainer;

string Latitude = (eventargs.FindControl("txtLatitude") as TextBox).Text;

string Longitude = (eventargs.FindControl("txtLongitude") as TextBox).Text;

string UTMXCoordinate = (eventargs.FindControl("txtUTMXCoordinate") as TextBox).Text;

string UTMYCoordinate = (eventargs.FindControl("txtUTMYCoordinate") as TextBox).Text;

if ((string.IsNullOrEmpty(Latitude) || string.IsNullOrEmpty(Longitude)) && (string.IsNullOrEmpty(UTMXCoordinate) || string.IsNullOrEmpty(UTMYCoordinate)))

args.IsValid = false;

else if ((!string.IsNullOrEmpty(Latitude) && !string.IsNullOrEmpty(Longitude)) || (!string.IsNullOrEmpty(UTMXCoordinate) && !string.IsNullOrEmpty(UTMYCoordinate)))

args.IsValid = true;

else

args.IsValid = true;

}
