To trace the parent control

I want to trace all the parent controls of a control (e.g) if i have a form which contains 开发者_StackOverflow社区panel which in turn contains another panel which contains button, i want to trace all the parents(form,panel,panel) from button how to do that?

You can try something like

private List<Control> FindParentList(Control control)
{
    List<Control> retVal = new List<Control>();
    Control c = control;
    while (c.Parent != null)
    {
        Control parent = c.Parent;
        retVal.Add(parent);
        c = parent;
    }
    return retVal;
}

And to call the method use

List<Control> parentList = FindParentList(button1);

The property Parent (inherited on every control from Control.Parent) provides access to the parent control. One can follow these references all the way up to the top-level Form.
