RadAjaxLoadingPanel with Telerik Report to PDF

[john81]

Is there any way to get the RadAjaxLoadingPanel to work with a Telerik report that is output as a PDF file?  The report takes a long time to generate so I'd like to show a loading screen or have some way to indicate that the pdf file is generating.  If I try to use the RadAjaxLoadingPanel, I'm getting a Sys.WebForms.PageRequestManagerParserErrorException because the code to programatically create a PDF from a Telerik report uses Response.BinaryWrite.

So is there any way to either...

show progress when a pdf file is being programmatically created from a Telerik report

OR

create a pdf file programmatically created from a Telerik report without using Response.BinaryWrite (in which case I could use the RadAjaxLoadingPanel to show progress)

Any options / solutions to this? I'm looking to solve the same issue.

Hi guys,

This is not possible for two reasons:

• exporting requires a postback and you cannot use loading panel.
• even if you use client script to invoke it, after the export the response does not return to the page and the loading panel/page you show cannot be hidden/stopped.
