Syncfusion Blazor Scaffolding

5 Dec 202310 minutes to read

Syncfusion provides Visual Studio Scaffolding for the Syncfusion Blazor platform, that allowing you to quickly add code that interacts with data models and reduce the time it takes to develop with data operations in your application. Scaffolding simplifies the creation of Razor and Controller action methods for Syncfusion Blazor DataGrid, Charts, Scheduler, Diagram, Tree Grid, Rich Text Editor, and Document Editor, and PDF Viewer controls.

NOTE

Check that at least one Entity Framework model exists, and the application has been compiled once. If no Entity Framework model exists in your application, refer to this documentation to generate the Entity Framework model. After the model file has been added, check that the required DBContext and properties are added. Now, build the application, and try scaffolding. If any changes made in the model properties, rebuild the application once before perform scaffolding.

NOTE

The Syncfusion Blazor Scaffolder is available from v17.4.0.39 for Blazor server-side application and provided the Scaffolding support to Blazor client-side application from v18.4.0.39.

Add a scaffolded item

The steps below assist you to how to add a scaffolded item to your Blazor application.

NOTE

Before use the Syncfusion Blazor Scaffolding, check whether the Syncfusion Blazor Template Studio Extension installed or not in Visual Studio Extension Manager by clicking on the Extensions -> Manage Extensions -> Installed. If this extension not installed, install the extension by follow the steps from the download and installation help topic.

  1. If the application type is Blazor ServerSide, right-click the Pages folder in the Solution Explorer, click Add, and then select New Scaffolded Item..

    Scaffolded add-in from server project

    If the application type is Blazor Hosted, right-click the Controllers folder from {Project Name}.Server application in the Solution Explorer, click Add, and then select New Scaffolded Item.

    Scaffolded add-in from the hosted project

    NOTE

    Scheduler control is not applicable for Blazor Hosted application.

  2. In the Add New Scaffolded item dialog, select Syncfusion Blazor Scaffolder and then click ‘Add’.

    Choose Syncfusion Scaffolding from Visual Studio Add scaffold dialog

  3. In the Syncfusion UI Scaffolder dialog, select the desired control to perform scaffolding, and then click Next.

    Choose required control

  4. The Syncfusion UI Scaffolder dialog for the selected control will be displayed. As application requirements, enter the Controller/Service Name and Razor Name, then select the active application’s required Model Class and its relevant Data Context Class, and then click Next.

    Choose required Model

  5. The dialog for the selected control feature will be opened in the Syncfusion UI Scaffolder. Select the required features, update the necessary data fields, and then click Add.

    For ServerSide Application, both Local data and Remote data types will be available.

    Choose required selected control features for the serverside project

    For Hosted Application, Remote data type only available.

    Choose required selected control features for the hosted project

  6. With the selected features of the Syncfusion control code snippet, the Controller/Service file and the corresponding Razor files are generated.

    If you select Local Data, the service file and razor file will be added to the application.

    Required Controller and Razor files added in the project for the selected control

    If you select Remote Data, the controller file and razor file will be added to the application.

    Required Controller and Razor files added in the project for the selected control

  7. Then, add navigation to the created razor file based on your requirement to open on the webpage.

  8. If you installed the trial setup or NuGet packages from nuget.org you must register the Syncfusion license key to your application since Syncfusion introduced the licensing system from 2018 Volume 2 (v16.2.0.41) Essential Studio release. Navigate to the help topic to generate and register the Syncfusion license key to your application. Refer to this blog post for understanding the licensing changes introduced in Essential Studio.

Syncfusion Blazor Command-line Scaffolding

Scaffolding command-line for Syncfusion Blazor allows you to quickly add code that interacts with data models and reduce the amount of time it takes to develop with data operations in your application. Scaffolding simplifies the creation of view file and Controller action methods for Syncfusion Blazor DataGrid, Charts, Scheduler, Diagram, Tree Grid, Rich Text Editor, Document Editor, and PDF Viewer controls.

NOTE

Verify that at least one Entity Framework model exists. If your application lacks an Entity Framework model, use this documentation to create one. After you’ve added the model file, double-check that the necessary DBContext and properties have been added. Now, build the application and experiment with scaffolding. If any changes made in the model properties, rebuild the application once before perform scaffolding.

Install Command-line Scaffolding

Install syncfusion.scaffolding tool globally by using below command.

dotnet tool install -g syncfusion.scaffolding

Update Command-line scaffolding

Update syncfusion.scaffolding tool globally by using below command.

dotnet tool update -g syncfusion.scaffolding

Add a scaffolded item from command-line

The steps below will assist you to how to add a scaffolded item from command-line to your Blazor application.

NOTE

Before adding the scaffolded item from command-line, check whether the dotnet-aspnet-codegenerator tool is installed or not by dotnet tool list -g command in command prompt. if it is not installed, then install dotnet-aspnet-codegenerator tool globally by using this command dotnet tool install -g dotnet-aspnet-codegenerator.

  1. After installed syncfusion.scaffolding tool, we can invoke syncfusion_scaffold command and it shows the available controls

    syncfusion_scaffold

    CommandLine Scaffold Available Controls

  2. To add a scaffolded item from command-line you must invoke syncfusion_scaffold application like below syntax

    syncfusion_scaffold [control][arguments]

    Parameter Description Control
    -p|–project Path to .csproj file in the project. All Controls
    -cname|–controller-filename Name of controller file to be added in project. All controls
    -vname|–view-filename Name of view file to be added in project. All Controls
    -m|–model Database model name with namespace (example: WebApplication1.Models.Tasks). All Controls
    -dc|–db-context DbContext name with namespace (example: WebApplication1.Models.TasksContext). All Controls
    -pkey|–primary-key Set Feature name/column name as primary key. Data Grid/Tree Grid
    -tid|–treegrid-id Id of Tasks. Tree Grid
    -pid|–parent-id Parent Id value Tree Grid/Diagram
    -x|–x-axis X-axis of Chart Charts
    -Y|–Y-axis Y-axis of Chart Charts
    -sid|–scheduler-id Id of Scheduler Event. Scheduler
    -stime|–start-time Start Time of Scheduler Event. Scheduler
    -etime|–end-time End Time of Scheduler Event. Scheduler
    –is-all-day Set IsALLDay for Scheduler Event. Scheduler
    -did|–diagram-id Id of Diagram layout. Diagram
  3. If you run the syncfusion_scaffold [control] command, the parameters of control shown like below image.

    control parameter details

  4. Run the following command to generate controller and view files through command-line by passing required arguments of the given control.

    syncfusion_scaffold {controlName} --project "{projectFileNamewithPath}" --model {model} -dc {dbContext} -cname {controllerName} -vname {viewName} [controlMantoryParameter] [controlMantatoryParameterValue]

    CommandLine Scaffold

  5. As we can see controller and view files generated successfully and also added the Syncfusion NuGet packages and styles which is required to render Syncfusion control.
