I have 2 radAsyncUpload controls and both of them are required on my content page. I also have multiple textboxes and a listbox that are also required.
I have tried using the RequiredFieldValidator and it works but not on the radAsyncUpload control. I search the forum and found the customvalidator to check but that works for the radAsyncUpload control but not the other controls.
Is there a way I can check all my controls before I send anything to the server?
I'm using Telerik Tools 2013 Q1 NET 45. This page is using a master page.
Any help would be greatly appreciated
