    Hello friend, @PrashantRami ,

    I have something for you :
    You can draw your 4 fiels named for example : pin_x ; where x=1,2,3.

    then, set your change events for your fields (I think the last field dont need that) like :

    pin_x.Changed+= pin_x_TextChanged();

    void pin_x_TextChanged (object sender, EventArgs e)
        pin_(x+1).BecomeFirstResponder(); // Sets focus

    I hope that helps,
    Mabrouk Mahdhi.

    there is no event called UITextField.Changed. i tried

    Pin0.ValueChanged += Pin0_ValueChanged;
    private void Pin0_ValueChanged(object sender, EventArgs e)
