Check Filesize Clientsite - CustomValidator

[Dirk Eberhardt]

Hello,
I readed this article about checking the filesize on clientsite: http://www.telerik.com/help/aspnet-ajax/upload_howtoclientfilesize.html

Now I customized this code for my project:

<script type="text/javascript">
 function checkUploadedFilesSize(progressArea, args)
 {
   if (!progressArea.confirmed &&
       args.get_progressData().RadUpload.RequestSize > 10485760)
     {
       progressArea.cancelRequest();
     }
  }

</script>

It work's, but how can I set a custom validator to "false" after I canceld the request to show the user an error message??

My cumstom validator looks like this:

<asp:CustomValidator
  ID="checksizevalidator" runat="server"
  Display="Dynamic">
The total size of the selected files is more than the limit.
</asp:CustomValidator>

Thanks in advance for your help.

Regards
Dirk

Hi Dirk Eberhardt,

I have prepared a sample project that demonstrates how this can be done. All in all the idea is to manually show the validator, since it won't pay attention to the IsValid property being changed after submit.
