using namespace System::Web::UI::Adapters;

public ref class CustomControlAdapter: public ControlAdapter

   virtual void Render( HtmlTextWriter^ writer ) override
   {
      // Access Browser details through the Browser property.
      Version^ jScriptVersion = Browser->JScriptVersion;
      
      // Test if the browser supports Javascript.
      if ( jScriptVersion != nullptr )
      {
         // Render JavaScript-aware markup.
      }
      else
      {
         // Render scriptless markup.
      }
   }

Remarks

A ControlAdapter object determines the client browser capabilities from the HttpBrowserCapabilities object that is returned by the Browser property. This enables the ControlAdapter object to render browser-specific markup or otherwise modify the behavior of the Control.
