Hi @mc,

You can return an object in Razor Pages, but it may not work as what you done. Razor Pages are designed to return IActionResult objects for HTTP responses. If you return a plain object, it won't automatically serialize to JSON or render properly.

To properly handle this, you should return a JsonResult to send JSON data, especially for AJAX requests.

For Example, modify your code like below:

public async Task<IActionResult> OnPostDeleteAsync()
{
    return new JsonResult(new MySuccessMessage());
}

I'm guessing you have a client application, maybe JavaScript, that calls OnPostDeleteAsync(). The problem you are trying to solve, is making an AJAX call to delete a resource. But, you need the results of the delete operation to update the document loaded in the browser. See the following tutorial if you are trying make AJAX calls to Razor Page handlers and process the results.

If the above does not answer your question, then explain what you are trying to do.
