If I load the table from an IEnumerable List, it works fine. But if I load the table form an object List that has been 'converted' be using the .AsEnumerable, the page is lock from user input. Meaning the pagination won't work, radiobutton won't work, calendar pickers won't work. The only thing I can do is enter text into text boxes. Why does it make a difference how I load the table? By the way, I'm using MudBlazor components.

The difference in behavior you're experiencing between loading data from an IEnumerable List versus an object List converted using .AsEnumerable() is likely due to how Blazor handles state changes and renders components.
1. Reference vs. Value Types:
When you use .AsEnumerable() on an object List, you're creating a wrapper around the original list. This wrapper might not be recognized by Blazor's change detection mechanism as easily as a direct IEnumerable List.
2. Change Detection:
Blazor relies on change detection to know when to re-render components. The way you're converting the object List to IEnumerable might be interfering with this process.
3. Component Lifecycle:
MudBlazor components might be relying on specific interfaces or methods that are present in the original IEnumerable but not in the converted version.
4. Memory References:
The converted list might not be maintaining the same memory references, causing issues with event bindings and state management.

It seems like you are facing a specific issue related to loading your table data in a Blazor application using MudBlazor components. The behavior you described, where the page becomes unresponsive to certain user interactions after loading the table from an object List converted to IEnumerable using .AsEnumerable, can be attributed to how Blazor handles data binding and component lifecycle.
When you load the table directly from an IEnumerable List, Blazor can efficiently track changes in the data collection, allowing components to update accordingly. However, when you convert an object List to IEnumerable using .AsEnumerable, you may inadvertently detach the data from its original source, causing Blazor to lose track of changes and rendering the page unresponsive to certain user interactions like pagination, radio buttons, or calendar pickers.
To resolve this issue, you may need to ensure that your data is bound properly and that any conversions maintain the necessary data relationships for Blazor to work effectively. It's important to maintain proper data binding and lifecycle management in your Blazor components to ensure smooth interaction and updates across your application.
If you are comfortable sharing some code snippets or more specific details about how you are loading and binding your data, I'd be happy to provide more targeted guidance or examples to help you address this issue effectively.
