Example

The following sample code illustrates how to find out what UIElement the mouse is over.

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinScrollBar

Private Sub ultraScrollBar1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ultraScrollBar1.MouseDown

    Dim mainElement As UIElement
    Dim element As UIElement

    ' Get the control's main element
    mainElement = Me.ultraScrollBar1.UIElement

    ' Get the element at that point
    element = mainElement.ElementFromPoint(New Point(e.X, e.Y))

    If element Is Nothing Then Return

    Debug.WriteLine("Mouse down on an " + element.GetType().ToString())
    Debug.Indent()

    ' Walk up the parent element chain and write out a line 
    ' for each parent element.
    While Not element.Parent Is Nothing

        element = element.Parent
        Debug.WriteLine("is a child of an " + element.GetType().ToString())
        Debug.Indent()

    End While

    ' Reset the indent level
    Debug.IndentLevel = 0

End Sub

C#

using System.Diagnostics;
using Infragistics.Win;
using Infragistics.Win.UltraWinScrollBar;

private void ultraScrollBar1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{

	UIElement mainElement;
	UIElement element;

	// Get the control's main element
	mainElement = this.ultraScrollBar1.UIElement;
 
	// Get the element at that point
	element = mainElement.ElementFromPoint( new Point( e.X, e.Y ) );

	if ( element == null )
		return;

	Debug.WriteLine( "Mouse down on an " + element.GetType().ToString() );
	Debug.Indent();

	// Walk up the parent element chain and write out a line 
	// for each parent element.
	while (element.Parent != null )
	{
		element = element.Parent;
