I have a webdialogwindow with two textbox controls, Submit and Cancel buttons on it. User enters the required input and clicks OK to submit. I need to verify the input and display error messages. How that should be done?
You will find such example implemented in one of our online samples at: http://www.infragistics.com/samples/aspnet/editors/using-asp.net-validatorsIt describes the use of ASP.NET Validators à asp:RequiredFieldValidator, asp:CompareValidator, etc in combination of Infragistics editors. It is possible to look through the code in use as well for the implementation itself.
