Hello Richard,

Yes, If you set it programmatic via code, it will not work. You would need to close it manually.
However, the current DialogBoxServiceProvider does not show how to close. You can find in our Contacts MVVM DevForce C# Sample. Or, perhaps you can add the close function in DialogBoxSeviceProvider.

  internal static void CloseCurrentWindow()
  {
          FrameworkElement element = ISFocusManager.GetFocusedElement() as FrameworkElement;
          IWindow window = UXWindow.GetWindowHost(element);
          if (window != null)
              window.Close();
  }

 Then, call  DialogBoxServiceProvider.CloseCurrentWindow();, to close DialogBox.

Btw, can you let me know more detail about message box issue?

Hello,

Unfortunately, there is no sample in our site. However, you should able to call your code when resize the pane. SizeChanged event is called everytime you resized the pane.

Hello Richard,

Did you use the same NavigationServiceProvider in our template? If you want to see our implementation about UXDialogBox with MVVM, I suggest to check our sample, Contacts MVVM C# Sample. It sure will show you how to open,close or handle error correctly.

Hello,

Please try to use SizeChanged event for your scenario. It should work as expected.

Hello,

It's hard to achieve it in XHTML since the rendering is trouble some in your scenario. However, when it does have a workaround. You would need to add time out when call SetHeigth and wgDoResize.

example

 function syncHeight() {
        var grid = ISGetObject('WebGrid1');
        
        var newHeight = (document.documentElement.clientHeight - 250) + 'px';
        if ((document.documentElement.clientHeight - 250) > 48) {
            window.setTimeout(function () { grid.SetHeight(newHeight); wgDoResize(true, true); }, 500);
        }
    }
