Using Barcode creation for ASP.NET Control to generate, create EAN-13 Supplement 5 image in ASP.NET applications.
The inconsistency in type formatting between requests and responses is a little confusing at rst because it s hard to understand why this would have been done I guess since the WCF team owns the web service portion of things now, they can dictate what they want

One common practice performed during development is refactoring, where you modify your code as you go along, making small tweaks that enhance the maintainability and readability of the code During these times, classes can change names and namespaces Be sure to keep in mind that any changes performed on the server that affect the data types on the client could warrant changing your proxy calling code

Using Barcode printer for .NET framework Control to generate, create Data Matrix ECC200 image in Visual Studio .NET applications.
The KnownType attribute that we discussed in the Complex Data and Serialization section earlier in the chapter also comes into play when types are generated for the proxy class The use of the KnownType attribute adds that type to the registered types in the proxy In Listing 829, we can see that

not only is the BusinessEntities type registered, but also the Customer and Vendor types, even though they are not directly used by any of the methods on the web service The inclusion of known types in the proxy class assists the JSON serializer in determining the data type to use when converting the data before it is sent back to the server and then on the server when the Data ContractJsonSerializer attempts to convert the JSON to a NET data type

Using the Page Method Proxy Class

Using Barcode generation for .NET Control to generate, create GS1 128 image in VS .NET applications.
The page methods proxy class provides the method signatures and data type declarations for the ProductLookup and AdvancedProductLookup page methods we covered earlier The generation of this proxy class follows the same pattern as the web service proxy class, including a static representation and the reliance of the WebServiceProxy class to provide the underlying request and response functionality

In Listing 830, we can see that the calling pattern is similar to the web service proxy class and uses a similar static class approach to methods The name of the proxy class when using page methods will always be PageMethods, and the methods to call will always match the method names on the page The use of callbacks and user context is the same as in our web service proxy class, and so is the ability to set these values globally The one thing that page method proxy classes do not provide is a varying implementation approach using both instance and static representations The default static usage is all that is supported
Listing 830 Page Method JavaScript Proxy Calling Functions
function PageMethodLookupProduct() { criteriaProductNumber = $get("productNumber")value; PageMethodsAdvancedLookupProduct(criteria,onSuccess,onFailed); } function onSuccess(result, userContext, methodName) { $get("productDescription")value = resultDescription; $get("productPrice")value = resultPrice; } function onFailed(result, userContext, methodName) { alert("An error occured \n" + resultget_message()); }
WebServiceProxy Class
The SysNetWebServiceProxy class is the base class used for proxies generated by the ScriptManager and provides the web service request and response functionality for inherited classes The class contains properties to set the path of the service to call, the timeout for each request, the default user context data passed through the request call and made available to the callback functions, the default success callback function, and the default failure callback function (see Table 86) The class also contains an invoke method that calls the speci ed web service dependent on the path and handles all the pre- and post-processing that occurs during the call (see Table 87)
