I am a beginner here. I am trying to create a page with custom property where it wants to allows the editor to drag and drop a file. While uploading I need to show the progress bar of uploading status. Help me to do this, any examples please.
My one word answer would be: why?
Editors can already upload files "For this Page" via drag-and-drop in Episerver out-of-the-box, see "Uploading Media" here. Unless I'm missing something it seems like you'd just be reinventing the wheel?
