If we’re going to implement paging in our UI, the first thing we’ll need is code that will return a paged set of data from the database. The ultimate goal is to only retrieve the exact quantity of filtered, sorted records from the database.
I’m going to be using the AdventureWorks database for some of these examples. The code in the GitHub project DOES NOT use AdventureWorks, it uses the YTGI Lookups database tables. You can get the AdventureWorks database from Microsoft’s site here: AdventureWorks Download
The complete solution that I show in this Series can cloned here: Paging Demo Download. This solution was created in Visual Studio 2019 Professional using MVC in .NET Core 3.1.
Here are three posts showing retrieving data in a paged format. Once you look at these, you can return to this post to continue to the next step.
Jack Yasgar has been developing software for various industries for two decades. Currently, he utilizes C#, JQuery, JavaScript, SQL Server with stored procedures and/or Entity Framework to produce MVC responsive web sites that converse to a service layer utilizing RESTful API in Web API 2.0 or Microsoft WCF web services. The infrastructure can be internal, shared or reside in Azure.
Jack has designed dozens of relational databases that use the proper primary keys and foreign keys to allow for data integrity moving forward.
While working in a Scrum/Agile environment, he is a firm believer that quality software comes from quality planning. Without getting caught up in analysis paralysis, it is still possible to achieve a level of design that allows an agile team to move forward quickly while keeping re-work to a minimum.
Jack believes, “The key to long term software success is adhering to the SOLID design principles. Software written quickly, using wizards and other methods can impress the business sponsor / product owner for a short period of time. Once the honeymoon is over, the product owner will stay enamored when the team can implement changes quickly and fix bugs in minutes, not hours or days.”
Jack has become certified by the Object Management Group as OCUP II (OMG Certified UML Professional) in addition to his certification as a Microsoft Certified Professional. The use of the Unified Modeling Language (UML) provides a visual guide to Use Cases and Activities that can guide the product owner in designing software that meets the end user needs. The software development teams then use the same drawings to create their Unit Tests to make sure that the software meets all those needs.
The QA testing team can use the UML drawings as a guide to produce test cases. Once the software is in production, the UML drawings become a reference for business users and support staff to know what decisions are happening behind the scenes to guide their support efforts.
