How can I know when a user hits submit?

Question

I have a simple textbox on my Windows Phone 7 application. I want to execute a method when the user types something in the textbox and confirms it.

My question is, how would I go about this? When I click the textbox in the emulator, a keyboard pops up, I'm guessing the preferred way is somehow capturing that submit event. Any guidance?

Answer 1

Consider checking for the Enter keypress. Ensure your XAML's TextBox has this method declared for the KeyDown event.

<TextBox Name="textBox1" KeyDown="OnKeyDownHandler"/>

private void OnKeyDownHandler(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter)
    {
        Debug.WriteLine("Enter");
        //do the work you want.

        //haven't found yet a good way to hide the keyboard explicitly.
        //setting focus to a control will hide the keyboard. unsure if there's
        //a Keyboard.Hide()
        SomeOtherControl.Focus();
    }
}

Ensure you then hide the keyboard if appropriate. Hiding the keyboard is achieved by setting focus away from the textbox.

Hi Sergio,

Would handling this in LostFocus address your requirement simply?

I just tried enter on a page with two textboxes using the sip and focus moved from one textbox to the other.
