Index of Currently Selected Row in DataGridView

Question

It\'s that simple. How do I get the index of the currently selected Row of a DataGridView? I don\'t want the Row object, I want the in

Answer 1

I used if get row value is clicked:

private void dataGridView_Product_CellClick(object sender, DataGridViewCellEventArgs e){
    int rowIndex;
    //rowIndex = e.RowIndex; //Option 1
    //rowIndex= dataGridView_Product.CurrentCell.RowIndex; //Option 2
    rowIndex = dataGridView_Product.CurrentRow.Index; //Option 3
}
