Touch support for panning

[Sehe]

I was curious if it is possible to add support for touch panning/scrolling to the RadGridView. All of our applications are for touch screens, and touch panning/scrolling would make the RadGridView much easier to use.

Thank you for the help.

Hello Scott,

Please check this blogpost. It is for Silverlight . However I believe the same approach may be adjusted to WPF as both data grids share the same APi and codebase.

I tried using the PanScrollBehavior class in my project, but it doesn't like the following line:

var contentPanel = this.scrollViewer.FindChildByType<Telerik.Windows.Controls.GridView.ScrollContentPresenter>();

It cannot find the ScrollContentPresenter. Do you know what the WPF equivalent would be?

Thanks,
Scott

After searching the internet for a while, I think I found a really clean way of adding the panning support. Basically you get a pointer to the GridViewScrollViewer and set the panning mode on it.

GridViewScrollViewer gvsv = this.MyGridView.ChildrenOfType<GridViewScrollViewer>().First();
if (gvsv != null)
{
     gvsv.PanningMode = PanningMode.Both;
}

This seemed to enable the touch panning for my application. Maybe this is a property you could expose at  the GridView level in future releases.

Hello Scott,

Yes that is the right solution. It is my mistake not mentioning that the ScrollContentPresenter was substituted by the GridViewScrollViewer recently.

Thanks for posting the solution to the forum ! I am updating your Telerik points.

In addition I want to share some good news. We are already working on adding this as a feature of RadGridView. We are aiming at internal support of panning , zooming and some kinetic scrolling.

Is there a way to support Drag and Drop in RadTreeView for WPF control?
Thanks!
