Due to the project needs . I used UploadCollection control to implement file upload.
I found a problem that when i drag a file into UploadCollection It doesn't work(upload) correctly.But if I click "plus" button to add a file .it can upload successfully.
So,I wanna find whats wrong with it.
Finaly,I found the abnormal code.
if i drag a file " this._aFileUploadersForPendingUpload[i].getValue()" it returns false
but i click "puls" button it returns true.
In my project code,i change the url & sendXhr status when i upload .
i tried many methods to fix it ,but i failed.
pls help me!
thanks vary much
