How can I tell when the “search” button is clicked when I set InputScope to search?

Question

For Windows Phone. How can I tell when the "search" button is clicked when I set InputScope to search on a TextBox? Is there an event?

Answer 1

When the InputScope is set to "Search", the "search" button is just a restyled "enter" button. So, assuming:

<TextBox InputScope="Search" KeyDown="SearchBox_KeyDown" />

the "search " button being pressed (on the SIP) can be detected with:

private void SearchBox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter)
    {
        // Do search...
    }
}

Answer 2

In addition to what Matt has (correctly) answered, if you handle e.PlatformKeyCode == 0x0A (as shown below) you can also respond to the Enter key being pressed on the host keyboard when running in the emulator without the SIP.

if ((Key.Enter == e.Key) || (e.PlatformKeyCode == 0x0A))
{
    // Do search...
}

Answer 3

Do you mean the hardware search button? It's not exposed. Similar question

Answer 4

For Windows Phone 8.1 Apps (not Silverlight) you may use VirtualKey

if (e.Key == Windows.System.VirtualKey.Enter)
{
    //Do Something.
}
