Abstract: the article we introduced the ArcGIS Server9.3 AJAX Client Callback solution. This program is supported by the version 92, 93 in the most recent version is still supported. However, another 93 versions also support the latest AJAX solutions, which we call ASP.NET AJAX solutions. Articles on the ArcGIS Server9.3 AJAX we introduce the Client Callback solution. This program is supported by the version 92, 93 in the most recent version is still supported. However, another 93 versions also support the latest AJAX solutions, which we call ASP.NET AJAX solutions. Note: EDN help documentation on the call ASP.NET AJAX partial postback solutions, in fact, correspond to the ASP.NET AJAX technology. In 2007, when Microsoft released ASP.NET AJAX development framework, VS2008 installed by default, the framework provides a complete client – server asynchronous communication program. AJAX framework provides a set of AJAX controls (ScriptManager, UpdatePanel server controls, etc.) and the API to manage asynchronous communication, through the Microsoft AJAX Library client dynamically update the front page. This allows developers to pit father even so CITIC Bank, CITIC credit card upgrade buried by an annual fee traps have to write client-side script will be able to achieve partial refresh. Generate partial page postback (partial page postback) the control we call the trigger, it must support IPostBackEventHandler, IPostBackDataHandler or INamingContainer interface, and registered by the ScriptManager. In fact most of the Web ADF space inherited IPostBackEventHandler interfaces, have been registered ScriptManager, such as Map, OverviewMap, Toolbar, etc. The TOC is somewhat different, it inherited a PostBackControl class that implements the IPostBackEventHandler interface. It is worth mentioning that there are ScriptManager in the page when, Web ADF will choose partial postback solution. On UpdatePanel with Web ADF, there are several points need to emphasize. First, we often put the UpdatePanel server control to achieve partial page refresh (partial page rendering). In fact, we can put them outside the UpdatePanel, this approach only when the page is loaded with the ScriptManager control loopback registration trigger on it. Two, Web ADF contains SciptManager already registered, trigger events, and sent back to the client how to update page content, so do not need to use the UpdatePanel contains the ADF. Worse, if the ADF into an UpdatePanel, it will reduce efficiency. Therefore, we strongly not recommended on the UpdatePanel inside the ADF. If Client Callback, as control is triggered by Web ADF, ASP.NET AJAX usage scenarios can be divided into two kinds: one, Web ADF triggers the partial page postback with Client Callback this scenario the first scenario is almost the same. The difference is, ASP.NET AJAX by CallbackResults registration form by the ScriptManager into the items returned. Second, the non-Web ADF triggers the partial page postback in this scenario, there are three options, namely, UpdatePanel, data items, dynamic script. Blocks. Each selection is supported by Microsoft, standard mode. Mentioned earlier, to achieve the ADF into the UpdatePanel refresh will cause reduced efficiency, it is mainly a look at the other two options (1) dynamic script. BlocksScriptManager allows server-side JavaScript function building blocks, run on the client. For the ADF refresh, script. Block will generally call processCallbakResult function to handle server-side coming CallbackResults. Note, when using this method, the page must contain an UpdatePanel control, but the UpdatePanel can be empty. Disadvantage of this approach is the need to escape characters for CallbackResult conversion, while in C # and VB.NET are not the same, need to pay attention. Another possible flaw is that all the registed script. Blocks are stored in memory, which may lead to unnecessary problems. This approach has some advantages. One is the need to achieve as complete as the UpdatePanel refresh, refresh to update only part of the project. Another benefit is that clients do not need custom handling code, you can have by processCallbakResult function to deal with. (2) data items of the ways you need to insert a custom JavaScript function used to register data item asynchronous response handling function that will send data items coming from the server to processCallbackResult function to deal with. JavaScript functions are as follows:
