Create your own texbox  /// /// Interop Enabled TextBox : This TextBox will properly handle WM_GETDLGCODE Messages allowing Key Input /// class IOTextBox : TextBox { private const UInt32 DLGC_WANTARROWS = 0x0001; private const UInt32 DLGC_WANTTAB = 0x0002; private const UInt32 DLGC_WANTALLKEYS = 0x0004; private const UInt32 DLGC_HASSETSEL = 0x0008; private const UInt32 DLGC_WANTCHARS = 0x0080; private const UInt32 WM_GETDLGCODE = 0x0087; public IOTextBox() : base() { Loaded += delegate { HwndSource s = HwndSource.FromVisual(this) as HwndSource; if (s != null) s.AddHook(new HwndSourceHook(ChildHwndSourceHook)); }; } IntPtr ChildHwndSourceHook(IntPtr hwnd int msg IntPtr wParam IntPtr lParam ref bool handled) { if (msg == WM_GETDLGCODE) { handled = true; return new IntPtr(DLGC_WANTCHARS | DLGC_WANTARROWS | DLGC_HASSETSEL); } return IntPtr.Zero; } }
