private DataGridViewCell clickedCell;

private void dataGridView1_MouseDown(object sender, MouseEventArgs e)
{
// If the user right-clicks a cell, store it for use by the shortcut menu.
    if (e.Button == MouseButtons.Right)
    {
        DataGridView.HitTestInfo hit = dataGridView1.HitTest(e.X, e.Y);
        if (hit.Type == DataGridViewHitTestType.Cell)
        {
            clickedCell =
                dataGridView1.Rows[hit.RowIndex].Cells[hit.ColumnIndex];
        }
    }
}

Private clickedCell As DataGridViewCell

Private Sub dataGridView1_MouseDown(ByVal sender As Object, _
    ByVal e As MouseEventArgs) Handles dataGridView1.MouseDown

    ' If the user right-clicks a cell, store it for use by the 
    ' shortcut menu.
    If e.Button = MouseButtons.Right Then
        Dim hit As DataGridView.HitTestInfo = _
            dataGridView1.HitTest(e.X, e.Y)
        If hit.Type = DataGridViewHitTestType.Cell Then
            clickedCell = _
                dataGridView1.Rows(hit.RowIndex).Cells(hit.ColumnIndex)
        End If
    End If

End Sub

Remarks

You can use this method to determine which part of the DataGridView control is located at the specified coordinates. For example, you can call this method - specifying the coordinates of a mouse click - to determine the row and column indexes of the clicked cell or whether a header cell or scroll bar was clicked.
