Examples

The following example shows how to retrieve the PointHitTestResult return value from the HitTest method.

// Respond to the left mouse button down event by initiating the hit test.
private void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    // Retrieve the coordinate of the mouse position.
    Point pt = e.GetPosition((UIElement)sender);

    // Perform the hit test against a given portion of the visual object tree.
    HitTestResult result = VisualTreeHelper.HitTest(myCanvas, pt);

    if (result != null)
    {
        // Perform action on hit visual object.
    }
}
' Respond to the left mouse button down event by initiating the hit test.
Private Overloads Sub OnMouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
    ' Retrieve the coordinate of the mouse position.
    Dim pt As Point = e.GetPosition(CType(sender, UIElement))

    ' Perform the hit test against a given portion of the visual object tree.
    Dim result As HitTestResult = VisualTreeHelper.HitTest(myCanvas, pt)

    If result IsNot Nothing Then
        ' Perform action on hit visual object.
    End If
End Sub

Remarks

You can also perform a hit test on a visual object by using a Geometry as a hit test parameter and returning the result as a GeometryHitTestResult. For more information, see How to: Hit Test Using Geometry as a Parameter.
