How to hide Windows Phone 8.1 soft keyboard effectively?

Question

I want to hide the soft keyboard when the Enter key is tapped, but no solutions works for me properly. (Windows Phone 8.1 Universal App)

This one just doesn't work:

if (e.Key == VirtualKey.Enter)
{
    textBox.IsEnabled = false;
    textBox.IsEnabled = true;
}

A method like this:

private void LoseFocus(object sender)
{
    var control = sender as Control;
    var isTabStop = control.IsTabStop;
    control.IsEnabled = false;
    control.IsTabStop = false;
    control.IsEnabled = true;
    control.IsTabStop = isTabStop;
}

works only partially. It's hiding keyboard only when I'm using textbox for the first time. On the second time keyboard is reappearing.

Answer 1

I just did something like that and it's working:

private async void makeRequest(string title, int page)
    {
        myTextBox.IsEnabled = false;
        myTextBox.IsTabStop = false;
        // here is my httprequest and changing itemssource of listview
        myTextBox.IsEnabled = true;
        myTextBox.IsTabStop = true;
    }
