Remarks

The DetermineRenderUplevel method is a helper function that is used primarily by the RenderUplevel property to determine whether the client's browser supports client script. For this property to return true, the following conditions must be true:

• The browser has client script enabled.

• The W3CDomVersion property of the HttpBrowserCapabilitiesBase object that is stored in the HttpRequest.Browser property is 1 or later.

• The EcmaScriptVersion property of the HttpBrowserCapabilitiesBase object that is stored in the HttpRequest.Browser property is 1.2 or later.

  Note

  This method is used primarily by control developers.
