    Inherits RadWindow

    Public Sub New()
        InitializeComponent()
        ' Disables inking in the WPF application and enables us to track touch events to properly trigger the touch keyboard
        InkInputHelper.DisableWPFTabletSupport()
        AddHandler Me.Loaded, AddressOf MainWindow_Loaded
    End Sub

    Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs)
        ' Enables WPF to mark edit field as supporting text pattern (Automation Concept)
        Dim asForm As System.Windows.Automation.AutomationElement = System.Windows.Automation.AutomationElement.FromHandle(New WindowInteropHelper(Me).Handle)

        'Dim asForm As Telerik.Windows.A = System.Windows.Automation.AutomationElement.FromHandle(New WindowInteropHelper(Me).Handle)

        '' Windows 8 API to enable touch keyboard to monitor for focus tracking in this WPF application
        Dim inputPanelConfig As New InputPanelConfigurationLib.InputPanelConfiguration()
        inputPanelConfig.EnableFocusTracking()
    End Sub

Hi,

We are not sure we understand the hole scenario but you could use the RadWindowInteropHelper rather than WindowInteropHelper. The RadWindowInteropHelper is located in the Telerik.Windows.Controls.Navigation namespace.

Hope this is helpful.

Hi,

There are multiple approaches that could be used in order to open either the on-screen keyboard or the touch specific on-screen keyboard in Windows 8. You could use the TouchDown and LostFocus events of the RadNumericUpDown control in order to open and close the keyboard. All you need to do is find where the TabTip.exe is located on the machine you are using and open it. We tested the scenario on a Windows 8 RT tablet and the file was located at (C:\Program Files\Common Files\Microsoft shared\ink\TabTip.exe). The next code snippets show the described approach:

<telerik:RadNumericUpDown TouchDown="RadNumericUpDown_TouchDown"
              LostFocus="RadNumericUpDown_LostFocus"/>

and in the event handlers:

private void RadNumericUpDown_TouchDown(object sender, TouchEventArgs e)
{
    if (File.Exists("C:\\Program Files\\Common Files\\Microsoft shared\\ink\\TabTip.exe"))
    {
        System.Diagnostics.Process.Start("C:\\Program Files\\Common Files\\Microsoft shared\\ink\\TabTip.exe");
    }
}

private void RadNumericUpDown_LostFocus(object sender, RoutedEventArgs e)
{
    if (System.Diagnostics.Process.GetProcessesByName("TabTip").Count() > 0)
    {
        System.Diagnostics.Process tabTip = System.Diagnostics.Process.GetProcessesByName("TabTip").First();
       tabTip.Kill();
    }
}

Hope this is helpful.
