Disable Keyboard Navigation

[Paul B]

Is there a way to disable keyboard navigation in the RadListView control when it's in IconsView? I want to have other keys fire the KeyDown event (e.g. Del) but not the keyboard arrow keys.

Hello Paul,

Thank you for writing.

You can achieve your requirement by creating a custom RadListView and overriding its OnKeyDown event handler:

public class CustomListView : RadListView
{
    public override string ThemeClassName
    {
        get
        {
            return typeof(RadListView).FullName;
        }
    }

    protected override void OnKeyDown(KeyEventArgs e)
    {
        if (e.KeyData == Keys.Left || e.KeyData == Keys.Right ||
            e.KeyData == Keys.Up || e.KeyData == Keys.Down)
        {
            return;
        }
        base.OnKeyDown(e);
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.

Hello, Nidal,    

The Hamburger Menu is a UX paradigm incorporating a collapsible navigation pane and a sidebar menu. It is used in the modern Windows 10 applications such as Groove, Mail and Calendar. The pane works as a top-level container of other controls added to the form. We decided to implement it inside the RadPageView and add a new view to it, the Navigation View. The new view also supports four different display modes covering various use cases: Auto, Minimal, Compact, and Expanded. Additional information is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/pageview/navigation-view/overview

You can also refer to our Demo application >> PageView >> Navigation view example. The Demo application can be found in the installation folder of the suite.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
