bug(DataTableDynamicContext): Items not updated after its DataTable got changed

[jvk-digres]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When I edit DataTableDynamicContext's DataTable GetItems() returns old items.

Expected Behavior

DataTableDynamicContext.GetItems() should always return rows from DataTableDynamicContext.DataTable.

Interactive render mode

Interactive Server (Interactive server-side rendering (interactive SSR) using Blazor Server)

Steps To Reproduce

Repo: https://github.com/jvk-digres/DataTableDynamicContext_ItemsNotUpdated

Exceptions (if any)

No response

.NET Version

NET9.0

Anything else?

There's also a bug (i think?) when adding new objects with DataTableDynamicContext.AddAsync. Items are not updated when OnAddAsync is set.

@jvk-digres hi. I submitted a PR for this issue in the repo. jvk-digres/DataTableDynamicContext_ItemsNotUpdated#1

For performance reasons, the method GetItems uses caching technology internally. If you need, we can design a property to control whether to use caching. However, I recommend reconstructing DataTableDynamicContext whenever you update the data source.

AddAsync

add sample code please take a look jvk-digres/DataTableDynamicContext_ItemsNotUpdated#2

@jvk-digres

add UseCache parameter default value is true

now. you can use this parameter to refactor your code

DataTableDynamicContext = new DataTableDynamicContext(dataTable, (context, column) =>
{
    column.Visible = true;
})
{
    UseCache = false
};

I can confirm this works.
