    Hello.

    In the UploadStarted event i have some validation of the fields, if the user left any in blank i need to send him a message and cancel de upload.  i manage doing  this using the RadUpload.CancelUpload().

    The problem is after validating and canceling the upload the screen with the RadUpload is still open but now with 0 files, and if the user fill the text that he left in blank before and try to upload again i get this error.

    My question is, where i can implement a way to Cancel the Upload if a validation is false?

    Ps: theres a screen in attach with the error.

    Thanks!!!

    My problem is still here,

    i read this article

    http://www.telerik.com/help/silverlight/radupload-features-upload-validation.html

    But i can't add the ValidateEvent, actualy theres no such event.

    I already add the reference to the Telerik.Windows assembly.

    Please i need this asap!

    Thanks!

    Hi Joao Paulo Grassi,

    We followed the steps in the mentioned help article and everything worked as expected ( we used Q2 Release dlls). Could you please check out our test project and let us know if we have missed something? You only need to upload a file named "test.txt". Thank you in advance for your cooperation.

    Hello.

    I download your sample project and  the ValidateEvent is not present for me. I think the version of my assemblies is old
    (Telerik.Windows.Controls 2010.2.812.1040). The problem is, that right now i can't update the version because the project is already "online".

    I create a sample project to show the error that i'm getting

    To see the error follow this steps:

    1 - Start the project

    2 - Try to upload a File Leaving the TextBox Name IN BLANK

    3 - A message shows saying that the Name is Required.

    4 - Fill the text and try to upload a file Again.

    5 - Bang! the error shows.

    I upload the project in 2Shared, please download it.
    http://www.2shared.com/file/CWXEcesa/RadUpload.html

    I need to implement a validation like this, i don't know if im missing something.

    Thanks again!

    Hello Joao Paulo Grassi,

    In your case, since you're using an old release of the control and there are known issues with your scenario there, I'd recommended you a slightly different approach.

    Instead of canceling an already started upload, you can handle the RadUpload.FilesSelected event to implement a validation logic, based on which to disable the Upload button until the user enters a valid value in the TextBox. Can you please examine the attached solution and let me know if this approach works for you? Thank you in advance.

    All the best,
