Question

I have a control with a tooltip. What i want is that when I hover over the control and the tooltip opens: if I then enter the tooltip with the mouse – this will trigger a mouseEnter event in order to trigger some other action. The closest I am to finding a solution to this is adding a ToolTipClosing event on the control with the trigger … but this will fire as soon as I leave the control – even if my mouse doesn’t enter the tooltip.
(Triggering a MouseEnter event on the tooltip itself doesn’t seem to get fired at all)

Here’s an example: (where I want to change the background of the border if I enter the tooltip)

XAML

<Border Height="300" Name="dummyBorder"
                        Width="200"
                        Background="Red" /> 
    <Label ToolTipService.InitialShowDelay="3000"
                           Content="Hover over here"
                           ToolTipService.ShowDuration="4000"
                           ToolTipService.Placement="Right"
                           ToolTipClosing="Label_ToolTipClosing"
                           Width="100"
                           HorizontalAlignment="Center"
                           Margin="10">
        <Label.ToolTip>
            <ToolTip Name="tt"  MouseEnter="ttBorder_MouseEnter">
                <Border Background="Brown"
                        Name="ttBorder"
                        MouseEnter="ttBorder_MouseEnter"
                        Width="100"
                        Height="50">
                    <TextBlock Text="This is a tool tip." />
                </Border>
            </ToolTip>
        </Label.ToolTip>
    </Label>

CodeBehind: (neither of these work)

private void Label_ToolTipClosing(object sender, ToolTipEventArgs e)
{
    if (tt.IsMouseDirectlyOver)
    {
        dummyBorder.Background = Brushes.Aqua;
    }
}

private void ttBorder_MouseEnter(object sender, MouseEventArgs e)
{
    dummyBorder.Background = Brushes.Aqua;
}

I specifically want to use a tooltip and not a popup. Is this possible?
Any help will be greatly appreciated!

Well (after 9 months and no answer) I guess that there is no way then. (Unless proven otherwise)
