Event onclick with treeview C#

@User-14814377 : If you paid for the expensive Telerik software, use their support system and documentation. Find out if their RadTreeView offers the WinForm Events shown here.

with WinForms, I frequently use code like this with a TreeView:

private TreeNode currentClkNode, currentDblClkNode;

private void treeView1_MouseDown(object sender, MouseEventArgs e)
{
    if(treeView1.GetNodeAt(e.Location) == null)
    {
        // handle mouseclick on TreeView client area
        // that is not a click on a Node
    }
}

// thiis will be called on a Node DoubleCliick
private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
    currentClkNode = e.Node;
    currentDblClkNode = null;
}

private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
    currentDblClkNode = e.Node;
}
