Question

I have readonly datagridview, I need in some specific case enable one cell after doubleclicking row (make readonly=false and make focus on this specific cell in current row (like entering it – the cursor should start to blink).

I have:

 private void dataGridView1_DoubleClick(object sender, EventArgs e)
{
       dataGridView1.Cells[3].ReadOnly = false;
}

But it doesn’t work. Why?

Answer 1

Try to set the currentcell of the Datagridview and call BeginEdit

 private void dataGridView1_DoubleClick(object sender, EventArgs e)
 {
    dataGridView1.Cells[3].ReadOnly = false;
    this.dataGridView1.CurrentCell = dataGridView1.Cells[3];
    dataGridView1.BeginEdit(true);
}
