The ItemCount property counts the items in the control. Use the ItemByIndex property to access an item giving its index. Use the AddItem, InsertItem, InsertControlItem, PutItems or DataSource property to add new items to the control. Use ChildCount to get the number of child items.

The following VB sample enumerates all items in the control:

Dim i As Long, n As Long
With Grid1.Items
    n = .ItemCount
    For i = 0 To n - 1
        Debug.Print .ItemByIndex(i)
    Next
End With

The following C++ sample enumerates all items in the control:

#include "Items.h"
CItems items = m_grid.GetItems();
COleVariant vtMissing; V_VT( &vtMissing ) = VT_ERROR;
for ( long i = 0; i < items.GetItemCount(); i++ )
{
	COleVariant vtItem( items.GetItemByIndex( i ) ), vtColumn( long(0) );
	CString strCaption = V2S( &items.GetCellCaption( vtItem, vtColumn ) ), strOutput;
	strOutput.Format( "Cell: '%s'\n", strCaption );
	OutputDebugString( strOutput );
}

The following VB.NET sample enumerates all items in the control:

With AxGrid1
    Dim i As Integer
    For i = 0 To .Items.ItemCount - 1
        Debug.Print(.Items.CellValue(.Items(i), 0))
    Next
End With

The following C# sample enumerates all items in the control:

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

The following VFP sample enumerates all items in the control:

with thisform.Grid1.Items
	local i
	for i = 0 to .ItemCount - 1
		.DefaultItem = .ItemByIndex( i )
		wait window nowait .CellCaption(0,0)
	next
