convert xaml to pdf?

[Nate Snowball]

I'm developing a LOB app for my company.  The app has forms and auto-complete textboxes for people to fill out.  Can syncfusion convert an xaml grid to pdf similar to the new api in windows 8.1 where you can render an xaml to bitmap?

If not, how would I go about using syncfusion to convert the generated bitmap into pdf?

Hi Nate,

Thank you for using Syncfusion product.

Yes it is possible to insert the images into the PDF document. At present, we do support JPEG encoded images.  Please find the sample available in the link below,

Please let us know if you need any further assistance.

Can you please give me an example where the image is already generated in the app and not from a file?  Remember that my app takes a snapshot of the xaml grid and creates a bitmap out of it.  What I'm trying to do now is create a pdf file out of this image.

One last question.  How do I set the page orientation?  I know it should be something obvious, but I can't seem to get it.  Many thanks.

Please find the below KB link to convert XAML to PDF in UWP platform, since we have marked WinRT as classic platform.

Its only converting the visible portion of the window, If the window has scroll bars or multipage, Its not converting the entire content.

Hi Padmaja, 

Thank you for contacting Syncfusion support. At present we do not have direct API for converting XAML to PDF. We can achieve this feature by converting the XAML to Image and then image to PDF. In this KB we have provided a work around sample for converting XAML to Image using the RenderTargetBitmap. XAML to image conversion depends on the UI element which we are given in the RenderAsync method. 

We have created a simple sample, enabled the scroll bar and added the Textbox control in bottom of the XAML page. The textbox is not visible in the current view of XAML page, and the text box preserved fine in the output PDF. Please make sure parameter of the  RenderAsync method is the parent of all UI element, so that the child controls will be preserved in the image. 

Code snippet: 

            //Create the Bitmpap from xaml page 

            await renderTargetBitmap.RenderAsync(SyncfusionForm); 

            var pixelBuffer = await renderTargetBitmap.GetPixelsAsync(); 

 

Please find the sample and output PDF below for your reference.

Output PDF:  http://www.syncfusion.com/downloads/support/forum/114548/ze/output1350238064 

Kindly check the above sample and let us know if you need further assistance on this.
