如何对Button进行编程以添加带有值的DataGrid行？

Question

My program has an email field, a password field, and a DataGridView to the right. There is a submit button as well. The submit button edits the preset row in the DataGridView but if clicked twice will just re-edit the contents of the first row.

dataGridView1.Rows[0].Cells[0].Value = txtEmail.Text;
dataGridView1.Rows[0].Cells[1].Value = txtPass.Text;

I'm wondering how I can program the button to add a NEW row with the value of txtEmail and txtPass . Is there a set method to adding rows via button? And once that is done how would I edit the most recently added row? This will present a new row with the new email and new pass every time data is submitted?

Any thoughts?

Assuming your DataGridView has only two columns, and that it's DataSource property is not bound to some collection or a DataTable , this should work:

private void btnAddInputToGrid_Click(object sender, EventArgs e)
{
    // add the new row, get its index
    var newIndex = dataGridView1.Rows.Add(txtEmail.Text, txtPass.Text);

    // select just the new row
    dataGridView1.ClearSelection();
    dataGridView1.Rows[newIndex].Selected = true;

    // select the cell you're interested in and put it in edit mode
    dataGridView1.CurrentCell = dataGridView1.Rows[newIndex].Cells[0];
    dataGridView1.BeginEdit(false);
}
