Scaffolding

  • 3 min to read

The DevExtreme Scaffolder for Visual Studio allows you to generate views (or Razor pages) and API controllers for DevExtreme-based controls.

Scaffold API Controllers

The Scaffolder allows you to create an API controller that uses Entity Framework Core Data Model to access data. The scaffolded API controller contains REST actions that perform CRUD operations on entities from the selected data context.

Follow the instructions below to scaffold a controller:

  1. In Solution Explorer, right-click the Controllers folder. In the invoked menu, hover the pointer over Add and then click Controller... or New Scaffolded Item....

    Add New Scaffolded Item in Context Menu

  2. In the Add Scaffold window, choose DevExtreme API Controller with actions, using Entity Framework and click Add.

    Add Scaffold Window

  3. In the Add Controller window, select the data context and model for which to generate the controller, enter the controller's name, and click Add.

    Add Controller Window

    Note

    If your project does not contain a data context, use the Getting Started with EF Core on ASP.NET Core with an Existing Database walkthrough.

Finally, scaffold a control that works with the controller.

Scaffold Controls

The following data-bound controls can be scaffolded:

You can insert these controls into an existing view or create a new view.

Note

Only the listed controls support scaffolding. To add other controls to a view, refer to the Create a Control article.

Insert Into an Existing View

Follow the steps below to scaffold a DevExtreme control and insert it into an existing view (or a Razor page).

  1. Open the view, right-click where the DevExtreme control's configuration should be inserted, and select Insert a DevExtreme Control Here in the context menu.

    Insert a DevExtreme Control Here on the context menu

    This invokes the following wizard:

    The Insert a DevExtreme Control window

  2. Follow the steps in the wizard:

    • Choose a control to scaffold.
    • Configure data binding: select a database context class, model class (required), and controller.
    • Configure control settings.
    • Click Add to finish scaffolding.

Create a New View

You can also create a new view (or a Razor page) with a scaffolded DevExtreme control on it.

  1. In Solution Explorer, right-click the folder where the view should be placed. In the invoked menu, move the cursor to Add and then click View.../Razor Page... or New Scaffolded Item....

    Add New Scaffolded Item on the context menu

  2. In the Add Scaffold window, choose MVC View with a DevExtreme Control or Razor Page with a DevExtreme Control and click Add.

    The Add Scaffold window

    This invokes the following wizard:

    The Add View window

  3. Follow the steps below in the wizard:

    • Enter the view name (or Razor page name). You can also mark the view as a partial view and specify a layout.
    • Choose a control to scaffold.
    • Configure the data binding: select a database context class, model class (required), and controller.
    • Configure control settings.
    • Click Add to finish scaffolding.
