UIElement Property (UltraCombo)

The main element for the combo's list portion (read-only)

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property UIElement As UltraComboUIElement

C#

public UltraComboUIElement UIElement {get;}

Example

The following sample code illustrates how UIElements can be used. It finds out what element the user pressed the mouse down on and outputs some context information about the element.

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid
Imports System.Diagnostics

   Private Sub ultraCombo1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ultraCombo1.MouseDown

       Dim mainElement As UIElement
       Dim element As UIElement

       ' Get the control's main element
       mainElement = Me.ultraCombo1.UIElement

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

       If element Is Nothing Then Return

       Debug.WriteLine("Clicked 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.UltraWinGrid;

private void ultraCombo1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{

	UIElement mainElement;
	UIElement element;

	// Get the control's main element
	mainElement = this.ultraCombo1.UIElement;
 
	// Get the element at that point
	element = mainElement.ElementFromPoint( new Point( e.X, e.Y ) );

	if ( element == null )
		return;

	Debug.WriteLine( "Clicked 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;
		Debug.WriteLine("is a child of an " + element.GetType().ToString());
		Debug.Indent();
	}

	// reset the indent level
	Debug.IndentLevel = 0;

}
