Change ActiveTab on DragOver
posted

Hi,

I've a TabControl with two Tabs. Now I want to drag something on one tab and if I drag over the TabHeader, the ActiveTab should change.

How can I find out, on which TabHeader I am ?

Thanks

    Hansjörg,

    You would have to get the UIElement from the current mouse position and check to see if you can get a tab element, then mark it as selected if it is not already.  The following code should cover this:

    private void ultraTabControl1_DragOver(object sender, DragEventArgs e)
    {
        Point clientPt = this.ultraTabControl1.PointToClient(new Point(e.X, e.Y));
        TabItemUIElement tabItemElement = this.ultraTabControl1.UIElement.ElementFromPoint(clientPt) as TabItemUIElement;
        if (tabItemElement != null)
        {
            UltraTab tab = (UltraTab)tabItemElement.TabItem;
            if (!tab.Selected)
                tab.Selected = true;                   
        }
    }

    -Matt
