Solution: WPF usercontrol does not accept userinput when host in a EdmTaskPAge

Issue: - Create a WPF usercontrol with any input and host in an EdmTaskPage. - Compile add-in and add to the vault. - Create task and choose add-in from dropdown. - See created tab to replicate issue.

Code below seems to fix the issue: ``` public partial class ConditionsWpf : UserControl { #region Public Constructors 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 ConditionsWpf() { InitializeComponent(); 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; } #endregion } ```
