ajax controls

Dynamic | Control from the issue of the post: Help me inside the need to dynamically get the handle value of the control, these days in the Vs.net tried, summed up a little experience, as follows: 1. Dynamically generating controls: Either in asp.net or in Windows application, each control can be used as a parent control, where some child controls are added, and of course add can be added manually, while dy

Asp.net| Server | control In the previous article, we introduced the basic concepts and basic theories of server controls, which are the cornerstones for building all custom server controls. However, relying on this knowledge alone is not enough to create a good server control. Because different types of server controls have different methods of creation, develop

First of all, let's talk about the difference between the two concepts (I believe we all know) 1. An ASP control is a server-side control, and HTML is a client control. 2. When the ASP control resolves at the server side, it translates into an HTML control that enables the client browser to be displayed. That means the final product is HTML control. 3. asp controls can only be resolved by installing the. NETFramework server, and HTML is java,php,as

a client-side technology. And XMLHttpRequest is dealing with the server side and client communication problems, so it is so important. Now, we probably have an understanding of the principles of Ajax. We can think of the server as a data interface, which returns a plain text stream, of course, the text stream can be in XML format, can be HTML, can be JavaScript code, can be just a string. At this time, XMLHttpRequest to the server side to request thi

OneThe properties for accessing all controls in the ASP. NET page pages are:Page.controlsThe structure of the control is a tree structure.Second, gets all the control instances of the specified type:1. The recursive method defines:Private voidGetcontrollistwhereT:control {foreach(Control controlinchControlCollection) { //if (control. GetType () = = typeof (T)) if(Control isT//This is cleanerResultcollection.add ((T) control); if(

Yes, there is no handleLightweight controls are sometimes called "windowless controls". They differ significantly from conventional controls in that they do not have window handles (hwnd attribute ). Therefore, they use less system resources than Internet applications.ProgramDistributed applications, and other applications that are easily constrained by system re

, after the client asynchronously obtains this result, it is not directly displayed on the page, but processed by javascript first and then displayed on the page. As for many popular ajax controls such as magicajax, other data types such as DataSet can be returned, but the results encapsulated by this process are essentially no big difference. 7. ajax advantages

principles of ajax. We can regard the server as a data interface, which returns a plain text stream. Of course, this text stream can be in XML format, Html, or Javascript code, it can also be a string. At this time, XMLHttpRequest requests this page from the server, and the server writes the text results to the page. This is the same as the normal web development process, after the client asynchronously obtains this result, it is not directly display
