The code sample you have given here is a important. Actually I also needed to add text boxes when the files are selected. This example full fills that requirement. But we need to save the file with the name which will be given within the text box.
I was able to manage that thing within the "FileUploadStarting" event as below.
void uploaderTest_FileUploadStarting(object sender, Telerik.Windows.Controls.FileUploadStartingEventArgs e)
e.UploadData.FileName = "SampleName.pdf";
Problem: When a different name is given, the progress bar is not working in that solution. :(. Can you please give a solution for that ASAP. (Did yo notice it?????????????)
