Thanks Shinu,
In fact it was only example. Already I can take some properties of the file such as AsyncUpload1.UploadedFiles[0].FileName; OR AsyncUpload1.UploadedFiles[0].ContentType; at Button1_Click event. But AsyncUpload1.UploadedFiles[0].InputStream object not available here because the file moved from temp folder to target folder by RadAsyncUpload. And I take error ; "Could not find file 'D:\XBonWebSite\Co\Images\Test\Test\138018175085315102010090.jpg'"
D:\XBonWebSite\Co\Images\Test\Test = Temporary Folder
D:\XBonWebSite\Co\Images\Test\Org = Target Folder
Why do asyncupload move uploaded file from temp to target at any postback? Can't I control this moving process?
I want to make this ;
