How to suspend Ui changing?

[jyswjjgdwtdtj]

I have a application which may change many properties in models in an instant, when do so, ui re-render constantly and makes my app stuck, while such high refresh rate is unnecessary, and i want app fluent more. So is there a method can suspend UI changing, like "SuspendLayout"? Or is there something i can do to solve this problem?

Sorry, I'm a beginner, so rather than an answer, take this more as a contribution to the discussion... Since I'm going through the Music Store tutorial, the first thing that comes to mind is using Delay in the binding — maybe that could help you. Alternatively, there's CanChange in the Community Toolkit.

Most changes queue layout and render passes to be done later. They're not performed immediately on every property change. However, limiting UI updates is still your responsibility - either through the newish Delay property in the binding system or through throttling updates (via System.Reactive, R3, etc). Especially if your updates are being pushed onto the dispatcher.

There is no way to stop the UI to update if your app is triggering renders by directly modifying properties bound to the UI.
Personally, I would avoid using the dispatcher or delays.

One possible solution, among others:
the app is setting values in Model classes (not bound to the UI), model generates update events only when needed and appropriate, telling view models to update accordingly by reading the model properties.
