Problem with DocumentViewerControl inside Callback panel
Problem reported by Chris Bart - 3/27/2024 at 1:21 AM

Hello.
I'm currently testing their DocumentViewerControl in ASP.NET Webforms.

I would like to use the DocumentViewerControl within a DevExpress callback panel.
I send a callback to change the document to be displayed in the DocumentViewerControl.

Problem:
After the callback, the DocumentViewerControl no longer exists.

Please first see these threads, it's similar problem with Microsoft's UpdatePanel:

The easy solution would be creating an ASPX page for the document viewer, and using an iframe ponting to that ASPX in your callback panel. You can pass your document via querystring to iframe src like DocViewer.aspx?doc=MyDocument.pdf

Hi. The solution with the iFrame works fine.
Thanks.
