    CuteWebUI:UploadAttachments - Require At Least One File Selected When ManualStartUpload="true"

    Reply Quote

    How do I require at least one file is selected when CuteWebUI:UploadAttachments has ManualStartUpload="true". I can see the files selected in the control (which have not been uploaded yet - hence PostFilesAttachments1.Items.Count = 0).

     

    Can one use an ASP.NET  RequiredFieldValidator or a CustomFieldValidator with CuteWebUI:UploadAttachments"  

    If so how?  If not, why not?
