Detecting the user pressing F10 in WPF

Question

My WPF application has behaviour triggered by the functions keys (F1-F12).

My code is along these lines:

private void Window_Ke         


        

Answer 1

This worked for me, for F1

Private Sub Window_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
    If (e.Key = Key.F1) Then
        ShowHelp()
    End If
End Sub

Answer 2

F10 launches the window menu. It's the same in all Windows apps.

It seems that Key.System is the expected value for the F10 key.

Answer 3

Answer with DataContext:

    public partial class BankView : UserControl
    {
        public BankView()
        {
            InitializeComponent();

            this.KeyDown += new KeyEventHandler(BankView_KeyDown);
        } 

        private void BankView_KeyDown(object sender, KeyEventArgs e)
        {
            try
            {
                switch (e.Key)
                {
                    case Key.F4:
                        ((BankViewModel)DataContext).OpenAccount();
                        break;
                }
            }
            catch (Exception ex)
            {
                ...
            }
        }

Answer 4

In addition to Yacoder's response, use the following to check for the F10 key:

case Key.System:
  if (e.SystemKey == Key.F10)
  {
    // logic...
  }

The SystemKey property will tell you which System key was pressed.
