Syncfusion is a popular company who makes software components used by developers worldwide. This tutorial will show how to use the back end code generated by
as a datasource for a Syncfusion ASP.NET Core UI Data Grid Control. The Syncfusion ASP.NET Core UI Data Grid Control
will be able to dynamically get data on demand using paging and sorting by column.
The generated back end code (middle tier, data tier, web api, stored procedures, etc) for either
can be reused in any project that needs data from a Microsoft SQL Server database. You can reuse the
generated back end code in a web, mobile, desktop, or even web api projects. You can easily fill UI components with as little as one line of code using the generated code as a datasource.
The code reuse also applies, but not limited to: SyncFusion Blazor, ASP.NET MVC UI, Angular, React, Xamarin UI, and many more.
You need the following for this tutorial:
Here's a snapshot of what we're trying to do:
- Microsoft Northwind Database (please Google it)
- Microsoft SQL Server 2003 and above
- You will need a User with an Admin username/password or with enough rights in the MS SQL Server (or Azure SQL). A blank username/password will not work.
- Visual Studio 2019 (the generated code will not work in Visual Studio 2017 and below)
- AspCoreGen 3.0 Razor Professional Plus or AspCoreGen 3.0 MVC Professional Plus (optional)
- AspCoreGen 3.0 Razor Ad-Hoc SQL Sample Project
- Syncfusion ASP.NET Core (EJ2) Demo Application
You need to have the Microsoft Northwind Database
installed in a Microsoft SQL Server
for this tutorial. Download and installation of this database is beyond the scope
of this tutorial. We will be using the Products
table to retrieve rows of data from this database.
1. Download the #5. Ad-Hoc SQL Sample Project
. You will see the project towards
the bottom of the page. Click the Download Sample Code
link. This web application project was generated by AspCoreGen3Razor
, the solution
contains 2 projects, a Web Application and a reusable Class Library project. We only need the Class Library project which consist of the Business Object and Data Tier class files and we can discard the web application project.
You can download and use any of the six (6) projects from
AspCoreGen3Razor's Web Generated Project Examples
AspCoreGen3MVC's Web Generated Project Examples
. Or generate your own code using AspCoreGen3Razor
. Any of these
will work, just follow along with the tutorial.
2. Download the Syncfusion Community License
. Install it in your computer and open the demo project in Visual Studio 2019.
You can use the Grid component for any Syncfusion products listed above, they will work just fine. If you already bought a Syncfusion License, then the demo application
should already be installed in your computer/system, in this case just follow along (no need to download). The Syncfusion Community License is free to individuals and small companies who makes less than a million dollars a year.*
3. Open the EJ2CoreSampleBrowser.sln
solution (in Visual Studio 2019) that was installed in your computer. In my case, the solution file can be found in
C:\Users\Public\Documents\Syncfusion\ASP.NET Core - EJ2\126.96.36.199
4. Copy the Class Library Project (NwndAdHcAPI)
that we downloaded in #1 to the C:\Users\Public\Documents\Syncfusion\ASP.NET Core - EJ2\
same folder where the 188.8.131.52
project/folder is located, as shown below.
5. Back in Visual Studio, add the NwndAdHcAPI.csproj
to the EJ2CoreSampleBrowser
solution by adding an existing project as shown below.
6. You should now have 2 projects showing in the Visual Studio Solution Explorer.
7. Open the AppSettings.cs
class under the NwndAdHcAPI
project and update the DatabaseUserName
for the Northwind Database
that you're using.
8. Change the NwndAdHcAPI
project's Target Framework to .NET Core 2.0
from .NET Core 3.1
because the EJ2CoreSampleBrowser
was made in .NET Core 2.0
. Right-click on the
project under the Solution Explorer
in Visual Studio, and then choose Properties
in the context menu. Under the Target Framework
, choose .NET Core 2.0
, and then save it.
9. Now that both the EJ2CoreSampleBrowser
projects are using the same Target Framework
, add the NwndAdHcAPI
project as a Project Reference
to the EJ2CoreSampleBrowser
10. Instead of creating a new MVC view, we will update/edit an existing one. Open the SortAPI.cshtml
view in the EJ2CoreSampleBrowser
project, under the Views/Grid
the code in the div
tags and replace with the code shown below:
11. Now open the related SortingAPIController.cs
controller under the Controllers/Grid
folder. Update the code to what you see below:
action method shown above will only return the amount of data the Syncfusion ASP.NET Core UI Data Grid component is asking for. The code that we deleted (Syncfusion example code) returns all data from
the database while the code we have above returns data on-demand.
action method is called whenever an event is triggered on the Syncfusion ASP.NET Core UI Data Grid component found in the SortAPI.cshtml
view. When the Sort or the Paging event is triggered,
the Grid passes a DataManagerRequest
to the GetData
As shown below, with the DataManagerRequest
, we can figure out:
- How many rows
(Page Size) to get from the database
- Where to start taking data from the database (Skip)
- The Column/Field to Sort and the Sort Direction (Ascending or Descending)
We can then retrieve just the right amount of data on-demand after getting these parameters.
The Syncfusion ASP.NET Core UI Data Grid component expects the Total Number of Records for the specific Datasource it's using, for our example, it's grabbing data from the Northwind
table. We need to return the Total Number of Records from the Products
table so that the Syncfusion ASP.NET Core UI Data Grid component will be able to calculate the number of Pages
The Syncfusion ASP.NET Core UI Data Grid component expects a JSON-formatted data that would contain parameters such as:
- count (Total Number of Records)
- result (Data)
12. Run the project by pressing F5 in Visual Studio. Go to the Sorting API
link under the Sorting
Click around to see the functionality of the Syncfusion ASP.NET Core UI Data Grid component with data supplied by the AspCoreGen3Razor
And we're done.
