mouse hovers ovr which cell in datagrid

[Lobo]

Hi,

I catch the moushover-event and a datagrid is returned as sender. How can I tell over which cell (or string inside that cell) the mouse hovers? Eventargs are empty, and the sender doesn't seem to have that information.

Thank you!

using System.Windows.Forms;

public class DataGridToolTips : DataGrid
{
private ToolTip toolTip1;
private int hitRow;
private int hitCol;

public DataGridToolTips()
{
hitRow = -1;
hitCol = -1;
toolTip1 = new ToolTip();
toolTip1.InitialDelay = 1000;
MouseMove += new MouseEventHandler( HandleMouseMove );
}

private void HandleMouseMove( object sender, MouseEventArgs e )
{
DataGrid.HitTestInfo hti = HitTest( new Point( e.X, e.Y ) );
if ( hti.Type == DataGrid.HitTestType.Cell
&& ( hti.Row != hitRow || hti.Column != hitCol ) )
{ // new hit row
hitRow = hti.Row;
hitCol = hti.Column;
if ( toolTip1 != null && toolTip1.Active )
toolTip1.Active = false; // turn it off
toolTip1.SetToolTip( this, this[ hitRow, hitCol ].ToString() );
toolTip1.Active = true; // make it active so it can show itself
}
}
}
