scroll using keyboard keys

Post by pawanpatel » Wed Apr 30, 2014 09:33 AM

Hello,

I need to scroll the winforms main viewer up, down, left, right using keyboard. How this can be done? is there any property to activate this or need to do custom programming using any keyup or keypress events?

Thanks,
Pawan

Hello Pawan,

By default the ImageViewer class does not allow to scroll an image using keyboard but you can extend functionality of image viewer.

First way, create a custom visual tool and use visual tool in image viewer. This is the best way.

The second way, create new class inherited from ImageViewer and override the behavior of class.

Best regards, Alexander

Hello,

Yes, I have added custom code in the KeyUP event handler and it is working fine!

Thanks,
Pawan

Hello,

SDK contains source codes of the ScrollPage class - the visual tool that allows to scroll the pages in the image viewer.
Source codes can be found here: [SdkInstallDirectory]\Examples\CSharp\ImagingDemosCommonCode\DemosCommonCode.Imaging\VisualTools\ScrollPages.cs

You can test the ScrollPages class in Imaging Demo:

Run Image Demo
Open multipage TIFF or PDF file
Select the Scroll Pages visual tool in toolbar
Scroll pages using mouse wheel

Best regards, Alexander
