I need to know if there's any way to validate empty radwatermark text box when the there's an empty string in the textbox. If the radwatermarktextbox is empty I need to get the red border and show a display that textbox is empty before adding the entries of these text box to gridview.
The control provides predefined validation error template for each of our themes, so you would only need to implement the data validation itself. I have prepared and attached project demonstrating sample solution using the IDataErrorInfo interface.
I have created a sample project to demonstrate this approach. The project is attached to this reply.
