WinForms - Whats wrong with this Focus Set?

Question

I have TextBox placed on a UserControl on a Panel which is placed in a Form. But couldn't set focus by this code,

mytxtBox.Focus();

ActiveControl = mytxtBox;

mytxtBox.Select();

Why its not working? How to set focus here?

Answer 1

If you wish to call this code from the Form you need to change the textbox modifiers property to public.

Then from the form you can call

userControl11.textBox1.Focus();
