The server then reverse constructs the GridView into a able, adds a row to the DataTable, binds it to the GridView, and sends it back to the client...Can it be simpler?When using Ajax data to request data, the data is usually in a simple format, such as String, with less information. Of course, you can also request back to XML, but XML data is redundant, and the client processing is much more troublesome than json.Can it be simpler?The above problems can be easily solved if the DataTable and JSO

Make full use of ViewState
ViewState provides a magic way to track the status of the control across backhaul, because it does not use server resources, does not time out, and applies to any browser. If you want to write controls, you must understand how to maintain the status in the controls ).
Developers can also use ViewState in almost the same way when writing pages, but sometimes the page contains the UI State values not stored by
. ViewState
ViewState is a mechanism designed by Asp.net to track status information between page backhaul by server controls.1. Disable ViewState
If you do not need to track the page status, for example, the page does not return (PostBack), you do not need to handle server control events, or the control content is recalculated every time the page is refreshed, you do not need to use ViewState to record the page status. You can set the EnableViewState

Because there is not too much use of viewstate, so I say is not necessarily, but it is certain that viewstate bring the other burden is inevitable, at least between the client and the server to pass data back and forth, you can save a lot of bandwidth, if

object can be tossed or bounced. When the supply advantage is used, the user can determine what to do only by looking at it: no graphs, no labels, no instructions. Complex things may need some explanation, but simple things should not. When the simple thing also needs to use the picture, the label to explain, the design is the failure.
One of the duties of a class designer is to reduce the gap between constraint and supply in the interface (GAP), match the target and some degree of freedom, an
