Route::Defaults Property
Gets or sets the values to use if the URL does not contain all the parameters.
Assembly: System.Web (in System.Web.dll)
public: property RouteValueDictionary^ Defaults { RouteValueDictionary^ get(); void set(RouteValueDictionary^ value); }
Property Value
Type: System.Web.Routing::RouteValueDictionary^An object that contains the parameter names and default values.
The Defaults property enables you to set the value for a URL parameter if the URL does not contain a segment for that parameter. You assign a RouteValueDictionary object to the Defaults property. Each element in the RouteValueDictionary object contains the name of a parameter and the value to use if the parameter is missing.
You can include a default value for a parameter that is not defined in the Url property as a segment. When ASP.NET routing handles a request, this default value is always passed to the route handler. When you construct a URL and you include a value for a default parameter that is not defined as a segment, the route will only be considered a match if the value that you provided matches the default value for the route.
The following example shows how to create a Route object and set the Constraints, DataTokens, and Defaults properties.
The following example shows a Route object whose Defaults property contains a parameter that is not part of the pattern in the Url property.
