RadDataPager for ASP.NET AJAX

URL Routing with ASP.NET 4.0 has never been easier. While it was first a luxury of ASP.NET MVC, WebForms applications got routing support with .NET 3.5 SP1. With version 4.0 of the framework, setting up URL routing is now a piece of cake. For those of you who have never heard of it: URL Routing enables your application to use URLs that do not directly map to physical files, but can instead represent a user-friendlier, more descriptive, logical structure. It is not URL rewriting and not URL mapping, where these effectively restore the original physical URL of the page down the request pipe.

As of Q2 2010 version of Telerik RadControls for ASP.NET AJAX, RadDataPager SEO paging now supports URL Routing. Setting it up is all a matter of giving values to a couple of properties in the RadDataPager:

Effectively, RadDataPager requires that you indicate routing is used for your application (by setting AllowRouting). It then needs to know:

1. The name of the route that leads to the target .aspx page containing the datapager - specified in RadDataPager by the RouteName property.

2. The name of the URL parameter that specifies the current page index - specified in RadDataPager by the RoutePageIndexParameterName property.

In the following example a route is defined in Global.asax file that leads to DataPagerRouting.aspx. The route defines a single URL parameter with a default value of 1. This parameter will be used to specify the current page index in RadDataPager. To take advantage of this route setup the RadDataPager is configured to use this route. The route name and the name of the URL parameter that specifies the page index are set.

CopyASPX

<telerik:RadDataPager runat="server" ID="Pager" PagedControlID="RadListView1" AllowSEOPaging="true"
    AllowRouting="true" RouteName="SeoRouting" RoutePageIndexParameterName="pager">
    <Fields>
        <telerik:RadDataPagerButtonField FieldType="Numeric" PageButtonCount="5" />
    </Fields>
</telerik:RadDataPager>

CopyC#

private void RegisterRoutes(System.Web.Routing.RouteCollection routes)
{
    routes.MapPageRoute("SeoRouting", "seopage/{pager}", "~/DataPagerRouting.aspx", true, new System.Web.Routing.RouteValueDictionary{ { "pager", "1" } });
}

CopyVB.NET

 

Private Sub RegisterRoutes(ByVal routes As System.Web.Routing.RouteCollection)
    Dim routeValueDictionary As New System.Web.Routing.RouteValueDictionary()
    routeValueDictionary.Add("pager", "1")
    routes.MapPageRoute("SeoRouting", "seopage/{pager}", "~/DataPagerRouting.aspx", True, routeValueDictionary)
End Sub
