Alternative to set focus from within the Enter event

Question

I have a textbox and in some cases in Enter event I need to set the focus to a different textbox.

I tried that code:

 private void TextBox1_Enter(object          


        

Answer 1

Postpone executing the Focus() method until after the event is finished executing. Elegantly done by using the Control.BeginInvoke() method. Like this:

    private void textBox2_Enter(object sender, EventArgs e) {
        this.BeginInvoke((MethodInvoker)delegate { textBox3.Focus(); });
    }

Answer 2

textBox.Select();

or

textBox.Focus();

or set TabIndex = 0 from properties of that textBox.

both methods are use to set focus on textBox in C#, .NET

Answer 3

You could handle the KeyPress event instead:

private void TextBox1_KeyPress(object sender, KeyPressEventArgs e)
{
   if (e.KeyChar == (char)Keys.Return)
   {
      e.Handled = true;
      TextBox2.Focus();
   }
}
