What this skill does
Using RendererInfo in Blazor The RendererInfo class in Blazor provides runtime information about the renderer that is executing the component. It is particularly useful for detecting whether a component is running interactively or statically, and for identifying the specific rendering platform (e.g., Server, WebAssembly, WebView). Key Properties IsInteractive Type: bool Description: Indicates whether the component is currently running in an interactive render mode. Usage: Use this to conditionally render UI elements that require interactivity, such as disabling buttons or showing loading indicators during static server-side rendering (SSR) or prerendering. Name Type: string Description: Returns the name of the renderer. Common Values: "Static": Running in static server-side rendering (SSR). "Server": Running in Interactive Server mode (SignalR). "WebAssembly": Running in Interactive WebAssembly mode. "WebView": Running in a Blazor Hybrid application (MAUI, WPF, WinForms). Common Scenarios 1. Disabling Inputs During Prerendering When a component is prerendered on the server, event handlers (like @onclick) are not active. You can use RendererInfo.IsInteractive to disable inputs until the interactive runtime takes over. 2. Rendering Different Content for Static vs. Interactive You might want to show a simple HTML form for static SSR and a rich, interactive component for interactive modes. Related Concepts AssignedRenderMode: A property on ComponentBase that tells you which render mode was assigned to the component (e.g., InteractiveServer, InteractiveWebAssembly, InteractiveAuto). Note that AssignedRenderMode might be null during static rendering. Important Notes RendererInfo is available in .NET 8.0 and later. It is a static class, so you can access it directly in your Razor markup or C# code without injection.
