![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | EvaluateExpression | Creates a URL that corresponds to specified URL parameter values and to a route URL format. (Overrides ExpressionBuilder::EvaluateExpression(Object, BoundPropertyEntry, Object, ExpressionBuilderContext).) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetCodeExpression | Returns a code expression that is used to perform the property assignment in the generated page class. (Overrides ExpressionBuilder::GetCodeExpression(BoundPropertyEntry, Object, ExpressionBuilderContext).) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetRouteUrl | Creates a URL that corresponds to specified route keys for a route URL format. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |

![]() | ParseExpression | When overridden in a derived class, returns an object that represents the parsed expression. (Inherited from ExpressionBuilder.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() ![]() | TryParseRouteExpression | Parses an expression into a collection of route keys and values, and optionally into a route name. |
The following example shows how to create markup that generates a hyperlink with a URL that is formatted for a route. The route is defined by using http://www.contoso.com/search/{searchterm} as the URL pattern.
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl="<%$ RouteUrl:searchterm=Bicycles %>">
Search for Bicycles
</asp:HyperLink>
The URL generated for this hyperlink would be http://www.contoso.com/search/Bicycles.
If the URL parameters provided to the RouteUrl expression are not sufficient to uniquely identify a route, you must include the route name. For example, if a Web application has two routes with searchterm as the sole URL parameter, the routes would have to be defined by using route names, and the hyperlink markup would resemble the following example:
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl="<%$ RouteUrl:searchterm=Bicycles,
routename=BasicSearchRoute %>">
Search for Bicycles
</asp:HyperLink>
