Here below is my scenario (thats actually mimicing the radWindow approach mentioned in this URL :
Using RadUpload Progress area in RadWindow ) in http://www.telerik.com/support/kb/aspnet-ajax/window/using-radupload-progress-area-in-radwindow.aspx)
1) I've a RadUpload (say 'radupload1) control on page1.aspx
2) an asp.net button to indicate upload processing Button (say 'button1') on the same page i.e, page1.aspx
3) a radWindow on the page1.aspx to open page2.aspx (detailing in next point below)
3) I've second page viz., page2.aspx (to open in radWindow from page1.aspx) with radprogressmanager and radprogressarea
4) I'm good about client side things like, opening page2.aspx in radWindow as soon as I hit button1 (as explainied in URL provided), radWindow Closes once upload progress reaches 100%, radwindow closes on Cancel Click (for big files like 50 MB),
However I'm primarily stuck with questions on server side
5) I need to handle custom steps in radProgressArea1 that include file upload/stream to webserver by radUpload, security checks, file conversion to a known standard format, queuing the file to a different service, update the db by DAL layer, then I need to let the radWindow close by itself.
I'm wondering how to stream the file in page2.aspx that has been selected using radUpload on page1.aspx?
the above URL was good for client side operations, is there any code sample/URL that might be handling similar scenario Or Can you please assist on this. Thank you in advance.
Not providing the sample application since my application just followed what was suggested in above URL.
(The low priority thing for me, "nice to have resolution" is : the radWindow cancel taking looong time (appearing like stuck) to refresh page1.aspx)
PS: I should be using Telerik rad controls version 2008.2.723.20
