How can I open xaml designer? - c++-winrt

enter image description here
enter image description here
In this document, a user can open designer by right-clicking the xaml file, and choose View Designer. But, there is no command in the tooltip. How can I activate the designer?
I use Blend for Visual Studio, Community 2019, version 16.9 preview 5, for WinUI 3.0.

As the support page for WinUI 3 points out, there is currently
No XAML Designer support

Applying a theme for a Telerik RadMultiComboBox

I have a vb.net application with many data-entry forms. On some of these forms a Telerik RadMultiComboBox control is used. I want the VisualStudio2012Light theme applied to all of these controls. I have no trouble applying the theme on all forms but one. On that one form, VisualStudio2012Light is not an option. I change the theme thru Properties...StyleSheet...ThemeName in the Visual Studio designer. I can manually enter it by typing it in but it does not stick and goes back to the default theme.
Using Visual Studio 2022 and version 2022.2.622.40 of Telerik.
What am I doing wrong?
If you are using RadForm, the ThemeName property should work. You can drag-drop the VisualStudio2012Light theme from the ToolBox to the RadForm. Check the following image: enter image description here
Then from the Visual Studio Properties window, you can navigate to the ThemeName property and set it to the desired theme. The last step is to apply the theme to all controls from the smart tag of the RadForm. This should do the trick:

VS 2022 Preview not showing the XAML designer

I've just installed VS 2022 preview to use Maui but there seems no way to see a designer view of the XAML, I want to drag and drop controls onto the page but all I get is an ancient looking XAML text view.
Visual Studio has removed the XAML designer. For now, there is no official plan to readd it.
But Visual Studio support Hot Reload to modify your apps managed source code while the application is running, without the need to manually pause or hit a breakpoint. You could preview the view at runtime when you change the UI. For more details, please check the blog. https://devblogs.microsoft.com/dotnet/introducing-net-hot-reload/
Like Cfun said, you could use live visual tree as well. It shows a tree view of the UI elements of your running Xamarin.Forms application. https://learn.microsoft.com/en-us/xamarin/xamarin-forms/xaml/live-visual-tree
For a WPF dotnet6 project, the XAML designer can be enabled here:
Don't know why it's disabled by default.

Properties pad doesn't work on Visual Studio 2019 for Mac

Properties pad doesn't work on my Visual Studio 2019 on Mac.
Attachment
I tried it on tools like Button or Label. I restarted visual, closed and opened files and nothing has changed.
On this video: https://youtu.be/76it8xVANbI?t=137 it looks fine but my properties pad doesn't display anything inside xaml file. When I click on filenames on the solution pad, properties pad displays info about those files.
I just searched the document and found this feature exists in Visual Studio 2019 for Mac version 8.4 Preview 1 (8.4.0.1935)
There says:
Xamarin:
You can now use the Properties panel to change your control's
attributes when editing Xamarin.Forms XAML. To open it, go to View >
Pads > Properties.
So you can update your Visual-Studio for Mac to version 8.4 Preview 1 (8.4.0.1935) to use this feather.

Why is the Xamarin.Forms toolbox view empty?

Visual Studio for Mac 7.0
I'm a new to use the Ide
image
in the picture,the toolbox is empty。
I entered it by hand
<Button Text="ok"/>
No code hints
How can I solve this problem?
This is working as expected. There is no visual designer for Xamarin.Forms. XAML must be written manually. You can however use the XAML previewer to assist you.
The Preview button can be displayed on the editor by right-clicking a
XAML file, and selecting Open With > XAML Viewer. The preview pane can
then be shown or hidden by pressing the Preview button in the
top-right corner of any XAML document window
Information about the previewer can be found here: https://developer.xamarin.com/guides/xamarin-forms/xaml/xaml-previewer/

How to set default XAML view in Visual Studio 2008

In Visual Studio 2008, when you add a new XAML window to a WPF Application Project, the default view you get is "split view" where the visual designer and the XAML code are shown one above the other in the same document.
I prefer an alternative view which you can get by double-clicking on either the Design or XAML tabs. The visual designer and the XAML are in separate side-by-side tabbed views. This makes it easy to switch between them
I want to know if it possible to make this the default view for all new XAML documents I add to my project, and where in the options you would set it.
Tools/Options/Text Editor/Xaml/Miscellaneous, check the "Always open documents in full XAML view"
