Blazor Code Generation with App Builder

    With .NET 6 we are officially supporting a version of App Builder with Blazor WASM and Server code generation options. This version comes live following the overwhelming feature requests around Blazor support.

    This means that you can now create any Blazor UI with simple drag & drop and get all of the production ready Razor, C# and CSS code in a single click for almost all components now.

    For a list of Blazor components availability see Generate App supported components section.

    You can generate both Blazor Web Assembly or Blazor Server apps based on your preferences and requirements.

    Blazor Code Generation from App Builder


    Trying to generate code for components not available yet will put a placeholder informing that such a component is not yet supported. This makes it possible for you not to refrain from developing more complex UI in the designer.

    In this article:


    As mentioned, Blazor Code generation feature supports a lot of new components and many are yet to come. Don't miss out on the Grid and Tree Grid code generation - as most of the grid features are now supported, like data binding that gives you the ability to run a Blazor application with a native grid component from Ignite UI for Blazor! Features like Excel-style filtering, Paging, Row editing, Cell selection and a lot more, are available to you.

    Blazor Code Generation

    After finalizing the design of your application and before previewing its code, pay attention to the Platform picker dropdown, located in the navigation bar just next to the Publish to Github and Preview action buttons. Choose the Blazor WASM or Blazor Server option to generate code for Blazor, Angular or Web Components if this is the preferred framework for your app. The picker remembers your choice and next time you go to AppBuilder you will have your desired framework preselected for you.

    Uploading an application to GitHub

    In addition to see your application in Preview mode or download it locally on the machine, there is the option for generating the full app code repository. In order to do that, simply go to the Generate app button and then connect your GitHub account to the App Builder.
