[Solved] Programatically Scroll Page

[Alessandro]

Hi, I already know how to get to the GridScrollViewer using

GridViewScrollViewer scrollViewer = grd.grdSrchResults.ChildrenOfType<GridViewScrollViewer>().FirstOrDefault();

What I need to know is how do I scroll page by page from there?  I don't want to scroll to the end but it seems that the GridViewScrollViewer is lacking methods like ScrollToNext() and ScrollToPrev() as if the user clicked an are on the scrollbar.

Thanks for any help here.

Hi Xavier,

I am sending you a sample project that describes an approach of scrolling horizontally and vertically in a RadGridView using specified scrolling offsets. Feel free to modify these values in order to fit best into your requirements.

Hi Ivan, this example only provides the web project. Can you provide the entire project? Thanks!

Hi Xavier,

That is very weird.

I have just downloaded the attached archive and here is what I see when I open it and go one level down.

Can you check again? There is one folder in the archive called SilverlightApplication64. When you go inside it -- what do you see. Is it different from my screen-shot? I see two folders and two solution files. One folder is for the web project and the other is for the Silverlight project.

Are you getting something different. If that is the case could you please provide a screen-shot.

Thanks in advance.

All the best,

Ross, you are right. There was another solution file that didn't include the project. Can you explain the offset values? Is the value of 30 arbitrary? How does one choose a value suitable for the application other than trial and error?

Hello Xavier,

Yes, it is an arbitrary value. You may calculate one that fits your case best, by using the measurement values of your RadGridView. For example you can  obtain GridViewRow's height in this way:

Copy Code

var Offset = (App.Current.RootVisual as MainPage).ChildrenOfType<GridViewRow>().Where(s => s.Item != null).First().ActualHeight;
