In my application I have a scenario where the user has one window open with the PDF Viewer control and they are looking at a pdf file then my application displays a modal dialog.  The user needs to be able to still scroll up/down in the PDF Viewer while this modal dialog is open.  I have given them some shortcut keys to scroll a page at a time (ctrl + pg up & ctrl + pg down) and then I send these commands to the control on the other window from the modal window.  This works for scrolling by a page but a lot of the time they just need to scroll a few lines.  Is there any API for the PDFViewer control that will allow me to send a command to scroll up or down a few lines?

Any help on this would be greatly appreciated!!!

Thanks in advance,
Lee

Hello Lee,

RadPdfViewer exposes MoveDownCommandDescriptor, MoveUpCommandDescriptor, MoveRightCommandDescriptor and MoveLeftCommandDescriptor which can be used to navigate in the document. Those command descriptors also take into account what is the current Mode (TextSelection or Pan) - when in selection mode the caret is moved, and in pan mode the document is scrolled. You can access the descriptors from the CommandDescriptors property of the control.

I hope this is helpful. Please, do not hesitate to contact us if you have any other questions.

Regards,
Alexander
