A boolean indicating if the parent sbould be checked.

Return Value

An object of the same type as the 'type' parameter, representing the context for this DayUIElement
Example
This sample uses GetAncestor to determine if we have clicked a RowUIElement on an UltraWinGrid, then uses GetContext to get at the RowUIElements associated row.

Imports Infragistics.Win
Imports System.Drawing
Imports System.Diagnostics

Public Function GetRowCellCount(ByVal pt As Point) As Integer
      
       ' Determine if we clicked on a row, first get the element under the mouse.
       Dim elementUnderMouse As UIElement

		elementUnderMouse = Me.UltraGrid1.DisplayLayout.UIElement.ElementFromPoint(pt)

       If Not elementUnderMouse Is Nothing Then
           Dim elementRow As UIElement 

				elementRow = elementUnderMouse.GetAncestor(GetType(UltraWinGrid.RowUIElement))
           If Not elementRow Is Nothing Then

               ' You now have the row element to do with as you please.
               ' Get the count of the cells collection
               Dim row As UltraWinGrid.UltraGridRow = elementRow.GetContext(GetType(UltraWinGrid.UltraGridRow))
               If Not row Is Nothing Then
                   Debug.WriteLine(row.Cells.Count.ToString())
                   Return row.Cells.Count
               End If
           End If
       End If

       Return 0

   End Function

{
	// Determine if we clicked on a row
	UIElement elementUnderMouse = this.ultraGrid1.DisplayLayout.UIElement.ElementFromPoint(pt);

			UltraWinGrid.UltraGridRow row = elementRow.GetContext(typeof(UltraWinGrid.UltraGridRow)) as UltraWinGrid.UltraGridRow ;

			if (null != row)
