Question

I have a form with a DataGridView (of 3 columns) and a Button. Every time the user clicks on a button, I want the get the values stored in the 1st column of that row.

Here is the code I have:

    private void myButton_Click(object sender, EventArgs e)
    {
        foreach (DataGridViewRow row in ProductsGrid.Rows)
        {
            if (this.ProductsGrid.SelectedRows.Count == 1)
            {
             // get information of 1st column from the row
             string value = this.ProductsGrid.SelectedRows[0].Cells[0].ToString();
            }
        }
    }

However when I click on myButton, the this.ProductsGrid.SelectedRows.Count is 0. Also, how do I ensure that the user selects only one row and not multiple rows?
Does this code look right?

Answer 1

Set DataGridView.MultiSelect=false and DataGridView.SelectionMode = FullRowSelect. This will make it so the user can only select a single row at a time.
