Textbox Focus Nullrefference exception

[Doug]

Hi

I've found a bug:
I have a radTextbox, which has a collapsed visibility by default, and I want to make it visible, and focus it on a button press, and I get a nullrefference exception:

   at Telerik.Windows.Controls.RadTextBox.OnGotFocus(RoutedEventArgs e)
   at System.Windows.Controls.Control.OnGotFocus(Control ctrl, EventArgs e)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

Code:
            inputTextBox.Text = _searchPattern;
            inputTextBox.Watermark = "enter name to find";
            inputTextBox.Visibility = Visibility.Visible;
            inputTextBox.Focus();

Best Regards
