/2 ). To support the following method, we need to add an additional saving parameter to our second path selection rule: Note that the new URL rule above matches "Search/[query]/[Page]". We also set the default page number to 1, in case the page number is not included in the URL (this is passed through as the anonymous type of the "defaults" attribute value ). Then, we can update our searchcontroller. Results Action Method to accept the page number parameter as a method parameter: In t

Introduction Microsoft's ASP. NET technology provides an object-oriented, event-driven programming model that combines the advantages of compiled code. However, the server-side processing model still has some technical limitations, many of which can be solved by the new features of Microsoft ASP. NET 3.5 Ajax extension

Abstract Developing highly interactive web applications based on AJAX technology in the past few months Program The design pattern quickly becomes popular. Currently, highly configurable web applications, such as Google Maps and A9, are using these technologies to create a rich client user experience. In fact, using Ajax technology for web development is not the result of recent research, but these technologies have been continuously updated and improved. This article has three purposes. Fi

In addition, the data is extracted from the data store in the form of an XML fragment, which then processes the data and provides it to the client. If you store data as an XML document, or if you store data in such a format: data as an XML external data layer, we have some other options. Shows how to extract and process the XML
