IsStillValid Property (HeadersRow)

True only if this row and all of its ancestor rows are still valid (read-only).

Syntax

Visual Basic

'Declaration
 
Public Overrides ReadOnly Property IsStillValid As Boolean

C#

public override bool IsStillValid {get;}

Example

If IsStillValid is false, then the row is invalid. More specifically, the UltraGrid has discarded the row and is not holding any reference to it. Following code implements a method that throws an exception if the passed in row is invalid.

Visual Basic

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid

  Private Sub EnsureRowValid(ByVal row As UltraGridRow)

      If Not row.IsStillValid Then
          ' Throw an exception if the row is invalid.
          Throw New Exception("The row is invalid.")
      End If

  End Sub

C#

using Infragistics.Shared;
using Infragistics.Win;
using Infragistics.Win.UltraWinGrid;
using System.Diagnostics;

private void EnsureRowValid( UltraGridRow row )
{

	if ( !row.IsStillValid )
	{
		// Throw an exception if the row is invalid.
		throw new Exception( "The row is invalid." );
	}

}
