WinCE ARM input virtual keyboard

Question

I want to show virtual keyboard when i click on textbox. Any ideas how to implement virtual keyboard to my app? This code does nothing at all.

    private void textBox1_GotFocus(object sender, EventArgs e)
    {
        inputPanel1.Enabled = true;
    }

    private void textBox1_LostFocus(object sender, EventArgs e)
    {
        inputPanel1.Enabled = false;
    }

Answer 1

LostFocus handler removing helped.

than i had to change position of keyboard. This is the only way to do it cuz of non existing property ://.. Maybe it will be useful for someone.
