I customized the project a bit, but suddenly after I had made some changes the silverlight upload control will not render any longer.
I am suspecting that something is going wrong in MultiFileUploadControl.cs. After the call to base.Render, control is resumed to the webpage, but only a completely blank silverlight application is shown. If i go to FileUploadTestPage.aspx or FileUploadTestPage.html
the silverlight control is rendered with no problem.
I have done some copying back and forth with the .xap files, but even replacing the one in ClientBin and the one in the SilverlightFileUpload project with FileUpload.xap from FileUpload\bin\debug does not help.
Any hints on how to fix/debug this?
