Use WindowsInteropHelper with RadWindow

[Phong]

Any ideas how to use WindowInteropHelper with the RadWindow?  WindowInteropHelper wants a Window.....

private void ShowWindow(RadWindow window)
{
    WindowInteropHelper helper = new WindowInteropHelper(window);
    helper.Owner = _windowHandle;
    window.Show();
}

Thanks,
PT

Hi Phong,

You could get and use the Window when the RadWindow is loaded. Here is the sample code:

private void Button_Click(object sender, RoutedEventArgs e)
        {
            var myRadWindow = new RadWindow();
            myRadWindow.Loaded +=new RoutedEventHandler(myRadWindow_Loaded);
            myRadWindow.Show();
        }

        void myRadWindow_Loaded(object sender, System.Windows.RoutedEventArgs e)
        {
            System.Windows.Window window = System.Windows.Window.GetWindow(sender as RadWindow);
            if (window == null)
            {
                return;
            }

            WindowInteropHelper helper = new WindowInteropHelper(window);
        }

I hope this helps.

Hi!

I have the same problem, and i tried your solution...

The problem is that i need the WindowsInteropHelper to set the Owner of my RadWindow, but if i do it in the Loaded event
i get this exception:

"Cannot set Owner property after Dialog is shown."

Apparently i need to set the Owner before the Loaded event, but i can´t get my WindowsInteropHelper before that.

Any suggestions?

Thanks

Hello Phong,

 
Unfortunately, when a RadWindow is created, it is placed in a Window control. There is no way to get the window before the LoadedEvent handler. This is a limitation of the RadWindow at this stage.

We will definitely consider this scenario with the RadWindow control.

Same problem here. Trying to use RadWindow as host window for VisualStudio wizard. 

It would be nice, if you implement event wich will be raised after back Window creation but before it shown. Usefull for System.Window tweaks.

For example here:

class WindowHostBase<br>
{
//...
 public virtual void Open(bool isModal)
    {
      WindowHostBase.hosts.Insert(this.FindIndexToAdd(), this);
      //<Raise event here>
    }
//......
}

As i see it is generic method for all your host types(WindowWithNoChromeWindowHost / MockWindowHost / SinglePopupWindowHost).

Or just here

class WindowWithNoChromeWindowHost<br>
{
//...
public override void Open(bool isModal)
{
      this.PrepareHost();
      this.Host.Loaded += new RoutedEventHandler(this.OnHostLoadedForFirstTime);
      base.Open(isModal);
       //<Raise event here>
      if (isModal)
        this.Host.ShowDialog();
      else
        this.Host.Show();
}
//...
}

Also this solves problems like: http://www.telerik.com/community/forums/wpf/window/radwindow-as-mainwindow.aspx

TaskBar display, title set and so one.

Hi Vladimir,

 
I would say that this is a good suggestion which we logged in our PITS here - http://www.telerik.com/support/pits.aspx#/public/wpf/13710 and we will consider implementing it for our further releases. Also, I am glad to update your telerik points as well.

It is sad that you ignoring feature requests update status. Also this FR is actual for WPF not for Silverlight

[George]

Hi Vladimir,

 
The feature request is not ignored, it's logged in our backlog system and we will look into it in our further releases. If it gets more votes, we will scheduled it for recent release. Also, we believe that the request is valid for both platforms (WPF and SL) as well.

All the best,
George

Hello Jason,

We moved the items from the PITS to the Feedback portal. You can find the same item on the following link:

Hope this helps.
