Problem with datagrid subcontrols (.NET 2003)

Question

Hi all,
I have a problem (C#, .Net 2003). My datagrid has some listboxes. I need to get mouse X and Y on datagrid through OnMouseDown on that listboxes to put ListBox.SelectedIndex in datagrid[?][?]. DataGrid.HitTest recieves coordinates on DataGrid, but ot Datagrid's subcontrol.
Could you give me some help with it, or maybe some links, dedicated that problem.

Well, i resolve that problem, but had another one... How to get the Height of ColumnHeader? DataGrid and DataGrid.TableStyles has not these members. I try out through FieldInfo and Layout, but it does not have that information.
