DataGrid dynamic data support

Sometimes your data comes from external API and you don't have a C# model for it. This demo shows how to implement such a scenario.

In this demo the grid binds to IDictionary<string, object> with 100 rows and 58 dynamically generated columns including various types (int, enum, string, DateTime, DateOnly, TimeOnly, Guid), demonstrating filtering and sorting on unknown schemas using PropertyAccess.GetDynamicPropertyExpression.
