Question 1

How do I bind Dynamic Data collections to a WPF ListView?

Accepted Answer

Use the Bind operator with ObserveOnDispatcher to ensure thread-safe updates. The README provides an example showing how to connect a SourceCache to an observable collection, which can then be bound to UI controls like ListView.

Question 2

Dynamic Data vs LINQ for collection operations?

Accepted Answer

Dynamic Data extends LINQ with reactive capabilities, automatically updating results when source collections change. While LINQ is for static queries, Dynamic Data handles dynamic, real-time data flows with operators like Filter and Sort that react to updates.

Question 3

Can I use Dynamic Data with ASP.NET Core for server-side logic?

Accepted Answer

Yes, Dynamic Data is a portable class library and can be used in ASP.NET Core for in-memory data manipulation, such as caching or real-time data processing. However, it's primarily optimized for client-side or UI scenarios with continuous updates.

Question 4

How to handle large datasets with pagination in Dynamic Data?

Accepted Answer

Dynamic Data supports pagination through the Page and Virtualise operators, which allow you to restrict data by index and page size reactively. These operators update automatically when the underlying data changes, as described in the Virtualisation section of the README.

Question 5

What's the difference between SourceCache and SourceList?

Accepted Answer

SourceCache is key-based and ensures no duplicates, notifying on adds, updates, and removes, while SourceList allows duplicates and only notifies on adds and removes. The README notes that Cache has more mature operators and is preferred for unique identifiers.

Question 6

How to filter collections dynamically based on user input?

Accepted Answer

Use the Filter operator with an observable predicate, such as an IObservable>. This allows the filter to update in real-time as user input changes, keeping the derived collection synchronized without manual intervention.
