how to set focus on the textbox on a dialog form using C#

Question

I have a textbox on dialog form, I want to default focus on it once form load, but for some reason, it does not happen. I have tried: Focus and form_load event and put focus method right after initialization of form.

Answer 1

You may call Control.Focus() method in Dialog Form's Activated event handler or set Tab Index order or use Select() method.

Answer 2

Use Form Shown event instead Load. Control cannot get focus while form doesn't shown.

public partial class Form1 : Form
{
   private void Form1_Shown(object sender, EventArgs e)
        {
              textBox1.Focus();
        }
}
