以编程方式选择一行DataGridView

Question

In my form application, there is a ( buttonNEW ) that selects NewIndexRow of DataGridView and I want to change index of datagridview with this button.

private void buttonNew_Click(object sender, EventArgs e)
    {
        if (dataGridView.CurrentRow.Index!=dataGridView.NewRowIndex)
        {
            dataGridView.ClearSelection();
            dataGridView.Rows[dataGridView.NewRowIndex].Selected = true;
            label1.Text = dataGridView.CurrentRow.Index.ToString();

        }
    }

But after clicking the button the index of DataGridView does not change. What is the problem?

Answer 1

This should work :-

int numofRows = dataGridView.rows.count;

dataGridView.CurrentCell = dataGridView.Rows[numofRows - 1].Cells[0];

Or I think you could also do this :-

dataGridView.CurrentCell = dataGridView.Rows[dataGridView.NewRowIndex].Cells[0];

Answer 2

Try with Linc:

private void buttonNew_Click(object sender, EventArgs e)
    { 

     dataGridView.Rows.OfType<DataGridViewRow>().Last().Selected = true;

   }
