Answer 1

You cannot set focus to a control if it has not been rendered. Form.Load() occurs before the controls are rendered.

Go to the form's events and double click the "Shown" event. In the form's shown event handler call the control.Focus() method.

    private void myForm_Shown(object sender, EventArgs e)
    {
        // Call textbox's focus method
        txtMyTextbox.Focus();
    }
