Here, the value for SearchString is used by the OnGetAsync() method in the Index.cshtml.cs class for ResourceLists. In the code snippet below, you can see that a LINQ Query filters the movies by a subset of movies where the Title contains the SearchString value. This was created by starting with the Core 3.1 Razor Pages Template in VS2019 and then updating it to view/edit data from the shared NetLearner database.

Page parameters can be included with the @page directive at the top of the page. To indicate that a parameter is optional, you may include a trailing ? You may also couple the parameter names with a data type, e.g. int for integers. This may come in handy when passing in QueryString parameters to be consumed by your Razor Page. Parameters are optional and are part of the route used to access your Razor Pages.
ASP.NET Core MVC – Model Binding
To differentiate from the 2019 series, the 2020 series will mostly focus on a growing single codebase (NetLearner!) instead of new unrelated code snippets week. Currently, on the view, the key _COLOR_ is being ignored and on the console, both the key _COLOR_ from SharedResource but also the key _WELCOME_ from index resource under Resources/Pages/ are being ignored. Run the Blazor web app from the NetLearner repo and try using the UI to add, edit and delete items.
Make sure you remove the restrictions mentioned in a previous post about NetLearner, which will allow you to register as a new user, log in and perform CRUD operations. In the sample project, browsing to the ResourceLists page with the search string “videos” includes any search results that include the term “videos”, as shown in the following screenshot. Razor Pages were introduced in ASP .NET Core v2.0, and briefly covered in my 2018 series, and with more detail in my 2019 A-Z series.
