SfPdfViewerControl.ViewMode FitWidth Behaviour

[Samuel Cheah]

The UWP app I am working on integrates SfPdfViewerControl to display the PDF document to the user. Due to the size of the PDF and the display dimensions of the app, the FitWidth mode has been set for the ViewMode. However, when resizing the PDF to fit the width of the view, the PDF loaded and shrink to fit the viewer, which appears to be "flashing" on the view. Is it possible to modify the behaviour of SfPdfViewerControl to resize and attach the PDF to SfPdfViewerControl, once the view (a customised dialog) is loaded before rendering it on screen, so that the PDF appears along the dialog without "flashing"?

Hi Gayathri,

Thank your for your prompt response. At the moment, the "flashing" when resizing the PDF document is the only problem that I have. The second request is negligible as the user is ok with the PDF viewer on our app.

Regards,

Samuel
