UIElement Property (UltraListView)

Returns the UltraListViewUIElement which represents this UltraListView control in the user interface.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property UIElement As UltraListViewUIElement

C#

public UltraListViewUIElement UIElement {get;}

Example

The following code sample demonstrates how to use the UltraListView control's UIElement property to locate descendant UIElements. In this example, the UIElement class' 'ElementFromPoint' method is used to hit test for an UltraListViewColumnHeaderUIElement; if one is found, the value of its 'Column' property is returned:

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinListView

    Private Function ColumnFromPoint(ByVal listView As UltraListView, ByVal point As Point) As UltraListViewColumnBase

        If listView Is Nothing Or listView.UIElement Is Nothing Then Return Nothing

        '	If there is an UltraListViewSubItem at the specified point,
        '	return a reference to its Column property
        Dim subItem As UltraListViewSubItem = listView.SubItemFromPoint(point)
        If Not subItem Is Nothing Then Return subItem.Column

        '	Try to find an UltraListViewColumnHeaderUIElement if we do,
        '	return a reference to its Column property
        Dim elementAtPoint As UIElement = listView.UIElement.ElementFromPoint(point)

        Dim headerElement As UltraListViewColumnHeaderUIElement = Nothing
        While (Not elementAtPoint Is Nothing)

            If elementAtPoint.GetType() Is GetType(UltraListViewColumnHeaderUIElement) Then
                headerElement = CType(elementAtPoint, UltraListViewColumnHeaderUIElement)
                Return headerElement.Column
            End If

            elementAtPoint = elementAtPoint.Parent
        End While

        Return Nothing

    End Function

C#

using Infragistics.Win;
using Infragistics.Win.UltraWinListView;
using System.Diagnostics;

		private UltraListViewColumnBase ColumnFromPoint( UltraListView listView, Point point )
		{
			if ( listView == null || listView.UIElement == null )
				return null;

			//	If there is an UltraListViewSubItem at the specified point,
			//	return a reference to its Column property
			UltraListViewSubItem subItem = listView.SubItemFromPoint( point );
			if ( subItem != null )
				return subItem.Column;

			//	Try to find an UltraListViewColumnHeaderUIElement; if we do,
			//	return a reference to its Column property
			UIElement elementAtPoint = listView.UIElement.ElementFromPoint( point );

			UltraListViewColumnHeaderUIElement headerElement = null;
			while ( elementAtPoint != null )
			{
				headerElement = elementAtPoint as UltraListViewColumnHeaderUIElement;
				if ( headerElement != null )
					return headerElement.Column;

				elementAtPoint = elementAtPoint.Parent;
			}

			return null;

		}
