Check RadTreeNode check box without effecting selection

[Travis]

Is there a way to check or uncheck a RadTreeNode checkbox without effecting the selection? For our app, it's kind of handy that we can do both, but it's also useful that we check or uncheck without impacting the selection. Or possibly vice versa (current behavior) might be acceptable. In either case, ????

Hi Michael,

Thank you for writing.

To do that, you can inherit from RadTreeView and override the OnMouseDown method, where you can save the SelectedNode prior the base call and restore it right after. Here is an example:

class MyTreeView : RadTreeView
{
    protected override void OnMouseDown(MouseEventArgs e)
    {
        TreeNodeCheckBoxElement element = this.ElementTree.GetElementAtPoint(e.Location) as TreeNodeCheckBoxElement;
        if (element != null)
        {
            RadTreeNode saveSelectedNode = this.SelectedNode;
            base.OnMouseDown(e);
            this.SelectedNode = saveSelectedNode;
            return;
        }
        base.OnMouseDown(e);
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadTreeView).FullName;
        }
    }
}

I hope this helps.
