In order to launch a window in external application package, please set the ApplicationUri property to the application package file which exists in the ClientBin of the Web project.

<Intersoft:UXDesktopDock x:Name="desktopDock">
    <Intersoft:UXDesktopDockButton Text="Local Application"
                                    Icon="/Images/App1.png"
                                    ApplicationUri="/Views/LocalWindow.xaml"/>
    <Intersoft:UXDockSeparator/>
    <Intersoft:UXDesktopDockButton Text="Application 1"
                                    Icon="/BookShelf.png"
                                    ApplicationUri="ExternalClientUIApp2.xap"/>
</Intersoft:UXDesktopDock>

In the above example, the ExternalClientUIApp2 package has its MainType assigned to a type that implements IWindow interface such as UXWindow. This enables the windowing framework to automatically dispatch the main type after the package was downloaded, then construct an instance and display the window to the desktop, as if the window were existed locally.

Should you need to implement this from a delegate command, you may try to set the Uri of WindowOptions to the corresponding xap file.

For more detail information, please check How to: Launch a Window in External Application Package in ClientUI documentation.

Hope this helps.

Hy Yudi,

thx for your replie.

I also check this HowTo to get an answer. But the ApplicationUri attribute is not available in Intersoft:UXStackItem.

I wanna do something like this:

<Intersoft:UXDesktopDockButton x:Name="xDesktopButtonSettings" 
       Icon="Assets/Icons/Settings.png" 
       UseImageLoader="False" 
       StackMode="GridStyle" StackGridMode="DynamicGrid" 
       Text="{Binding Source={StaticResource ResourceWrapperCore}, 
                      Path=ApplicationStrings.Einstellungen}" 
       StackTotalDisplayItem="0" StackGridItemWidth="128" 
       StackGridItemHeight="128">                

	<Intersoft:UXStackItem x:Name="xDesktopButtonSettingsStackItemBenutzer"
               Text="{Binding Source={StaticResource ResourceWrapperCore}, 
                              Path=ApplicationStrings.Benutzer}" 
               Icon="Assets/Icons/User.png" 
               Command="Intersoft:WindowCommands.LaunchApplication" 
               CommandTarget="{Binding ElementName=xCandasDesktop}"
               IsEnabled="True">
               <Intersoft:UXStackItem.CommandParameter>
                   <Intersoft:WindowOptions Uri="/Hainzl.Web.Silverlight.Candas.Benutzer;Hainzl.Web.Silverlight.Candas.Benutzer.BenutzerWindow" 
                         ForceSingleInstance="True" 
                         ReactivateExistingInstance="True" />
               </Intersoft:UXStackItem.CommandParameter>
         </Intersoft:UXStackItem></Intersoft:UXDesktopDockButton>

Hello,

As you noticed, you would need to use binding CommandParameter. After use WindowCommands.LauchApplication, you need to set CommandParameter binding.
Using ViewModel, you can set your windows option parameter. Since it has Uri property, you should be able to achieve your scenario.

Example:

 public WindowOptions CommandParameter
 {
      get
      {
         var wo = new WindowOptions()
         {
             Uri = new Uri("ClientUIExternalApp1;ClientUIExternalApp1.Views.SpecificWindow", UriKind.Relative),
             ForceSingleInstance = true,
             ReactivateExistingInstance = false,
             WindowName = string.Format("wndNotepad_{0}", Id),
             WindowGroupName = "Notepad",
             StartupParameters = this,
             WindowWidth = 800,
             WindowHeight = 600,
                   
        };
     return wo;
     }
}

Hope this helps.

Apologize for the delay in sending this.

Please allow me to guide about how to open a window from an external XAP file. In the step-by-step below, I assume that you have installed Intersoft WebUI Studio 2012 R1. We are about to launch a window when user click on a UXStackItem. The window is a specific page from an external XAP.

1. Open ClientUI Controls C# Sample (Visual Studio 2010 Solution) – start > All Programs > Intersoft WebUI Studio 2012 R1 > WebUI Studio for Silverlight 5 > Development Samples (Visual Studio 2010 Solution) > ClientUI Controls C# Sample (Visual Studio 2010 Solution).
2. After the solution is opened, press Ctrl + F5 to run the project.
3. A browser window with its url is set to: http://localhost:7373/Default.html (or something similar to this, url may vary on different development environment settings) will appear.
4. Modify the url into the following: http://localhost:7373/Default.html#/WindowControls/UXDesktopDock and press Enter.

The url will open Desktop Dock sample. You may try to click on one of the UXStackItem inside the Pictures UXDesktopDockButton (right next to the separator). In the next step, we are going to add our own UXStackItem, let’s say Custom. This stack item will be used to launch a window from a specific xaml page of external XAP.

In this sample, Default.xaml page which is located inside the “Views\UXClock” folder of Intersoft.ClientUI.Samples.UXInput project will be launch when user clicks our Custom UXStackItem.

To add external application to the UXShell and download the application package.

1. Open App.xaml.cs of Intersoft.ClientUI.Samples.WindowControls project.
2. Find the Application_Startup method.
   

   private void Application_Startup(object sender, StartupEventArgs e)
   {
       this.RootVisual = new MainPage(UXShell.Current.RootApplication);
   }

3. Modify the method to add external application to the UXShell and download the application package such as shown in the following.
   

   private void Application_Startup(object sender, StartupEventArgs e)
   {
       // External Application is Intersoft.ClientUI.Samples.UXInput
       ApplicationPackage app1 = new ApplicationPackage()
       {
           ID = "Intersoft.ClientUI.Samples.UXInput",
           Name = "Intersoft.ClientUI.Samples.UXInput",
           Source = new Uri("Intersoft.ClientUI.Samples.UXInput.xap", UriKind.RelativeOrAbsolute),
           Size = -1
       };
   
       UXShell.Current.Applications.Add(app1);
       app1.Download(true);
               
       this.RootVisual = new MainPage(UXShell.Current.RootApplication);
   }

To add and configure Custom UXStackItem.

1. Open Default.xaml of Intersoft.ClientUI.Samples.WindowControls project.
2. Add Custom UXStackItem inside the Pictures UXDesktopDockButton such as shown in the following snippet code.
   

   <Intersoft:UXDesktopDockButton Icon="/Intersoft.ClientUI.Samples.WindowControls;component/Assets/Images/Dock/pictures.png"
                                   Text="Pictures" StackMode="MenuStyle">
       ...
       <Intersoft:UXStackItem Text="Custom" Command="Intersoft:WindowCommands.LaunchApplication"
                               CommandTarget="{Binding ElementName=SampleDesktop}">
           <Intersoft:UXStackItem.CommandParameter>
               <Intersoft:WindowOptions ForceSingleInstance="True" ReactivateExistingInstance="True"
                                           Uri="/Intersoft.ClientUI.Samples.UXInput;Intersoft.ClientUI.Samples.UXInput.Views.UXClock.Default"/>
           </Intersoft:UXStackItem.CommandParameter>
       </Intersoft:UXStackItem>
   </Intersoft:UXDesktopDockButton>

3. Save the changes and press Ctrl + F5 to run the project.
4. After the browser window loaded, modify the url into the following: http://localhost:7373/Default.html#/WindowControls/UXDesktopDock and press Enter.
5. Try to click Custom UXStackItem and see the effect.

Hope this helps.
