DataGridView Control ContextMenuStrip

I'm using visual studio 2005 and I've created a datagridview control with a contextMenuStrip control associated with it.

My problem is that I need to know what cell the user clicked on (All I really need is the row) so that I can process what the user clicked on in the context menu properly.

This is the prototype for one of the handlers I get:

private void openDetailsToolStripMenuItem_Click(object sender, EventArgs e)

how would I go about retrieving the row number in the datagridview that the user right clicked on to trigger the context menu?

*** I DO NOT WANT TO RUN IN VIRTUAL MODE ***
I know of a way to solve this problem in virtual mode, but due to the way data is managed, and the fact that this is a relativly small set of data being displayed, I would prefer not to have to write extra handlers for celldataneeded etc.

Thank you in advance for your reply :)

You could probably use the "SelectedRows" property of the datagridview, and check that only one row is selected, or loop through each one, all according to what you plan to do...

Int32 selectedRowCount = YourDataGridView.Rows.GetRowCount(DataGridViewElementStates.Selected);
if (selectedRowCount == 1) {
  YourDataGridView.SelectedRows[0].Cells[0].Value.ToString();  //will retrieve the value of the cell in then leftmost column in the first selected row
}

Sorry I was a bit hasty posting the previous comment. The easiest way to retrieve the current row number is of course:
YourDataGridView.CurrentCell.RowIndex
