                                    we are building a solution that only contains a screen and a barcodescanner (no keyboard, no mouse),
                                    the solution at default runs a report and refreshes it every 30seconds.

                                    i need to be able to scroll down/up the report by using a function (triggered by the barcodescanner)  but not the "ScrollPageDown" function, this is too drastic

                                    i tried changing the value of the vertical scrollbar, but it doesn't work.

                                    Can you please advise how to do so ?

                                Hello Steven,

                                You can use the approach described in the How to scroll a document in the print preview to a specific page or brick code example to resolve this issue.

                                Thanks,
                                Elliot

                                  Hi Elliot,

                                  i cannot open the solution so i can't run it. But when i look at the code it doesn"t look like it could solve this issue that i have.

                                  When i click the scroll down or scroll up button i would like to have the scrollbutton to go down or up X amount of pixels.

                                  You can use the DocumentViewer.ViewManager.SetVertScroll method to scroll a report document in the Print Preview window. I have modified your sample project. Please review it in the attachment.

                                  Thanks,
                                  Elliot
