property Items.ItemCount as Long

Retrieves the number of items.

TypeDescription
Long A long value that indicates the number of items into the Items collection.

The ItemCount property counts the items in the control. Use the ItemByIndex property to access an item giving its index. Use the VisibleItemCount property to specify the number of visible items in the list. Use ChildCount to get the number of child items giving an item. Use the ItemChild property to get the first child item. Use the FirstVisibleItem property to get the first visible item. Use the NextVisibleItem property to get the next visible item. The NextSiblingItem property retrieves the next sibling of the item in the parent's child list. Use the ItemPosition property to change the item's position. Use the AddItem, InsertItem, InsertControlItem, PutItems or DataSource property to add new items to the control.

The following VB sample enumerates all items in the control:

Dim i As Long, n As Long
With Tree1.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_tree.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 AxTree1
    Dim i As Integer
    For i = 0 To .Items.ItemCount - 1
        Debug.Print(.Items.CellCaption(.Items(i), 0))
    Next
End With

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

EXTREELib.Items items = axTree1.Items;
for (int i = 0; i < items.ItemCount; i++)
{
	object caption = items.get_CellCaption(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.Tree1.Items
	local i
	for i = 0 to .ItemCount - 1
		.DefaultItem = .ItemByIndex( i )
		wait window nowait .CellCaption(0,0)
	next
