Use the Bold, Italic, Underline and StrikeOut properties to apply different font attributes to the item. Use the Caption property to display different parts of the caption using HTML format. Use the Font property to specify the control's font. Use the Group property to get the group that owns the item.

Private Sub ListBar1_AddItem(ByVal Item As EXLISTBARLibCtl.IItem)
    If (Item.Group.Index = 0) Then
        With Item
            .Bold = True
        End With
    End If
End Sub

The following C++ sample bolds all items in the first group:

{
	CItem item( Item ); item.m_bAutoRelease = FALSE;
	if ( item.GetGroup().GetIndex() == 0 )
		item.SetBold( TRUE );
}

The following VB.NET sample bolds all items in the first group:

Private Sub AxListBar1_AddItem(ByVal sender As Object, ByVal e As AxEXLISTBARLib._IListBarEvents_AddItemEvent) Handles AxListBar1.AddItem
    With e.item
        If (.Group.Index = 0) Then
            .Bold = True
        End If

The following C# sample bolds all items in the first group:

}

The following VFP sample bolds all items in the first group:
