Problem 2:
If i click to btnCancel_Click then after complete this form again control coming to AsyncFileUpload1_UploadedComplete this function. (C#)
i don't want that.
Problem 3:
I want to use generic handler how to use that?
Someone help me please! if you dnt understand the you can ask me again.
Last 3 days im stuck in file upload control.
Remember it is not MVC application it is application.
I want to implement async file uploader.
I dnt want to use extra button to save a file.
Its a single file uploader control.
I dnt to do maximum this in client side and upload and file save should handle by handler.
I serch lot i did not get actual solution.
If you have any other idea then you are welcome.
Thank you in advance.
