i want to save the index of row in database

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
int rowIndex1 = e.RowIndex;
int rowIndex2 = GetRowIndex();
}
private int GetRowIndex()
{
int rowIndex = this.dataGridView1.CurrentCell.RowIndex;
return rowIndex;
}
I use here 2 ways to find out index..i think you can easily convert it to vb.net..
