Use the ItemFiltered property to check whether an item is included in the control's filter. Use the FilterType property to specify the type of filter that's applied to a column. The ApplyFilter method should be called to update the control's content after changing the Filter or FilterType property. The ItemCount property counts the items in the control's list. Use the ItemByIndex property to access an item giving its index.

The following VB sample enumerates all items that are not included in the list when a filter is applied:

Dim i As Long
With Grid1.Items
    For i = 0 To .ItemCount - 1
        Dim h As EXGRIDLibCtl.HITEM
        h = .ItemByIndex(i)
        If (Not .ItemFiltered(h)) Then
            Debug.Print .CellValue(h, 0)
        End If
    Next
End With

The following C++ sample enumerates all items that are not included in the list when a filter is applied:

#include "Items.h"
CItems items = m_grid.GetItems();
for ( long i = 0; i < items.GetItemCount(); i++ )
{
	long hItem = items.GetItemByIndex( i );
	if ( !items.GetItemFiltered( hItem ) )
	{
		COleVariant vtItem( hItem ), vtColumn( long(0) );
		CString strFormat;
		strFormat.Format( "'%s' is not included\r\n", V2S( &items.GetCellValue( vtItem, vtColumn ) ) );
		OutputDebugString( strFormat );
	}
}

The following VB.NET sample enumerates all items that are not included in the list when a filter is applied:

Private Sub AxGrid1_ClickEvent(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxGrid1.ClickEvent
    Dim i As Long
    With AxGrid1.Items
        For i = 0 To .ItemCount - 1
            Dim h As Integer = .ItemByIndex(i)
            If (Not .ItemFiltered(h)) Then
                Dim cellValue As Object = .CellValue(h, 0)
                Dim strValue As String = ""
                If Not (cellValue Is Nothing) Then
                    strValue = cellValue.ToString()
                End If
                Debug.WriteLine(strValue)
            End If
        Next
    End With
End Sub

The following C# sample enumerates all items that are not included in the list when a filter is applied:

EXGRIDLib.Items items = axGrid1.Items;
for (int i = 0; i < items.ItemCount; i++)
	if (!items.get_ItemFiltered(items[i]))
	{
		object cellValue = axGrid1.Items.get_CellValue(i, 0);
		string strValue = cellValue != null ? cellValue.ToString() : "";
		System.Diagnostics.Debug.WriteLine(strValue);
	}

The following VFP sample enumerates all items that are not included in the list when a filter is applied:

with thisform.Grid1.Items
	local i
    For i = 0 To .ItemCount - 1
        local h
        h = .ItemByIndex(i)
        If (!.ItemFiltered(h)) Then
			wait window nowait .CellValue(h, 0)
        EndIf
    Next
