Use the CellForeColor property to change the item's foreground color. Use the ForeColor property to change the control's foreground color. Use the ClearItemForeColor property to clear the item's foreground color. The HTML colors are not applied if the item is selected. Use the SelectedItem property to specify whether an item is selected or unselected.

The following VB sample changes the foreground color for cells in the first column as user add new items:

Private Sub Tree1_AddItem(ByVal Item As EXTREELibCtl.HITEM)
    Tree1.Items.CellForeColor(Item, o) = vbBlue
End Sub

In VB.NET or C# you require the following functions until the .NET framework will provide:

You can use the following VB.NET function:

     Shared Function ToUInt32(ByVal c As Color) As UInt32
         Dim i As Long
	 i = c.R
	 i = i + 256 * c.G
	 i = i + 256 * 256 * c.B
	 ToUInt32 = Convert.ToUInt32(i)
     End Function 

You can use the following C# function:

private UInt32 ToUInt32(Color c)
{
	long i;
	i = c.R;
	i = i + 256 * c.G;
	i = i + 256 * 256 * c.B;
	return Convert.ToUInt32(i);
}

The following C# sample changes the foreground color of the focused item:

axTree1.Items.set_ItemForeColor(axTree1.Items.FocusItem, ToUInt32(Color.Red) );

The following VB.NET sample changes the foreground color of the focused item:

With AxTree1.Items
    .ItemForeColor(.FocusItem) = ToUInt32(Color.Red)
End With

The following C++ sample changes the foreground color of the focused item:

#include "Items.h"
CItems items = m_tree.GetItems();
items.SetItemForeColor( items.GetFocusItem(), RGB(255,0,0) );

The following VFP sample changes the foreground color of the focused item:

with thisform.Tree1.Items
	.DefaultItem = .FocusItem
	.ItemForeColor( 0 ) = RGB(255,0,0)
endwith
