Hello
I have an application where I need to run multiple windows on separate threads.
An example of what I need can be seen in an article in the MSDN section "Multiple Windows, Multiple Threads"
When performing my tests I realized that using the ChromelessWindow or Ribbon controls, I lose this possibility. Below is an example of my code example to reproduce the problem.
MainWindow.xaml code:
<Window x:Class="testeTH.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Height="40" Width="200" Click="ButtonBase_OnClick"></Button>
</Grid>
</Window>
MainWindow.xaml.cs Codebehind
public partial class MainWindow : Window
{
public Thread newWindowThread { get; set; }
public MainWindow()
{
InitializeComponent();
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
execTH();
//test tempWindow = new test();
//tempWindow.Show();
}
private void execTH()
{
newWindowThread= new Thread(new ThreadStart(() =>
{
// Create our context, and install it:
SynchronizationContext.SetSynchronizationContext(
new DispatcherSynchronizationContext(
Dispatcher.CurrentDispatcher));
test tempWindow = new test();
// When the window closes, shut down the dispatcher
tempWindow.Closed += (s, ex) => Dispatcher.CurrentDispatcher.BeginInvokeShutdown(DispatcherPriority.Background);
tempWindow.Show();
// Start the Dispatcher Processing
System.Windows.Threading.Dispatcher.Run();
}));
// Setup and start thread as before
// Set the apartment state
newWindowThread.SetApartmentState(ApartmentState.STA);
// Make the thread a background thread
newWindowThread.IsBackground = true;
// Start the thread
newWindowThread.Start();
}
}
test.xaml - the target window to run in a separate thread
<syncfusion:ChromelessWindow
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:syncfusion="http://schemas.syncfusion.com/wpf" x:Class="testeTH.test"
Title="test" Height="300" Width="300" >
<DockPanel>
<syncfusion:Ribbon x:Name="rb" DockPanel.Dock="Top">
</syncfusion:Ribbon>
</DockPanel>
</syncfusion:ChromelessWindow>
test.xaml.cs codebehind
public partial class test
{
public test()
{
InitializeComponent();
}
}
Just the fact call the window with the Ribbon control added to the target window has a xaml parse error.If I remove the Ribbon control and keep the window Chromeless can only run it just 1 time, even prompting his Dispacther the method BeginInvokeShutdown.
If I change the ChromelessWindow Window for easy and not put the Ribbon control, I can run the window in a separate thread.
How can I solve this by using these controls? Mostly. How to successfully call a window in a separate thread added the Ribbon control?

The solution example is attached for research.
The version of syncfusion wpf Essential Studio controls is 11.4.0.26
