WPF Label: Using the tooltip of the underlying Control

Question

I have a WPF Label which lays on top of Rectangles. These Rectangles have individual Tooltips. I want to show the Tooltip of the underlying Rectangle and ignore the Tooltip of the Label, how can I do this in wpf/c#.

You can set the IsHitTestVisible property of the labels to False so that the rectangles will receive the input from the mouse instead of the label.

Without the code it's har to tell how you actually want it to do

I would simply use the same method for the Tooltips

<Label Name="L1" ToolTipOpening="ToolTipMethod">
<Label Name="L2" ToolTipOpening="ToolTipMethod">

private void ToolTipMethod(object sender, ToolTipEventArgs e)
{
    //your code
}

I suppose you might want something like this:

This is just in pure xaml:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

    <Rectangle Grid.Row="0"
               ToolTip="Rectangle 1"
               Fill="Red" />

    <Label Grid.Column="0"
           Content="Label"
           HorizontalAlignment="Left"
           VerticalAlignment="Top"
           Width="50"
           Height="30"
           Background="LightBlue"/>

    <Rectangle Grid.Column="1"
               ToolTip="Rectangle 2"
               Fill="IndianRed" />

    <Label Grid.Column="1"
           Content="Label"
           HorizontalAlignment="Left"
           VerticalAlignment="Top"
           Width="50"
           Height="30"
           Background="LightBlue"/>

    <Rectangle Grid.Column="2"
               ToolTip="Rectangle 3"
               Fill="Red" />

    <Label Grid.Column="2"
           Content="Label"
           HorizontalAlignment="Left"
           VerticalAlignment="Top"
           Width="50"
           Height="30"
           Background="LightBlue"/>
</Grid>

Of course you can work out better ways on how to position the labels and defining their size to get what you want, this is merely an example.
