Hi,

I am trying to build the ExportToPdf functionality as in http://demos.telerik.com/aspnet-ajax/editor/examples/pdfexport/defaultvb.aspx

On pressing the button there is only a postback of the page, nothing happens further...no pdf export.

Suggestions?

Regards,
Marc

Hi,

For your convenience I have prepared a sample demo and a video http://screencast.com/t/UYqEtA6o, which shows how the export to pdf feature works.

Hi Rumen,

I know that this is working the way you pointed out, thank you.

The problem probably is that the editor is opened in a usercontrol with

Dim userControl As Control = Page.LoadControl(userControlName)

When I load the editor this way the ExportToPdf() function is not triggered?

Hi,

Do you export the content with Ajax? RadEditor's Export toPDF functionality cannot be ajaxified. This is because the Form element is modified during the procedure. In order to use ExportToPdf you need to trigger full postback. To achieve this you need to force Button1 to perform postback. You can find a detailed explanation and a solution in the following help article:
Force controls in ajaxified container to perform PostBack.

If your scenario is other, open a support ticket and provide a simple working project that demonstrates the problem.

That is a very clear answer Rumen, thank you.

Other question: Is it possible to skip the opening of the PDF in new or same window?
In my scenario I only want to save the editor's content in a server side PDF file.

I have already build the save functionality succesfully but it keeps me showing the PDF itself or the PDF dialogue.

Hello,

You can find attached here an example demonstrating how to silently export the editor's content as PDF on the server using the new OnExportContent event property of RadEditor.

All the best,

Thanks Rumen. That is the setup I am using.
How to proceed if the Radeditor1.ExportToPdf() is part of larger subroutine, in my case the saving of a database record?

It is no option to exit the OnExportContent Sub with a response.redirect, as it is part of a larger set of code.

Hi,

The only possible way to interrupt the ExportContent event is to invoke Response.Redirect() - AJAX call is not possible because ExportToPdf modifies the form of the returned value to be displayed (opened) as a PDF document.
