Hi Ian,
Actually
MaxFileInputsCount and
InitialFileInputsCount cannot work together with
MultipleFileSelection. This is a limitation of RadAsyncUpload control. However you may check the number of selected files in
OnClientFilesSelected event and prevent selecting of more than 3 files by canceling the event. Note that additional input field will be added. This is a development issue which was resolved and the fix for it will be included in the upcoming Service Pack. Until this happens you may use the suggested workaround:
