Also possible security hazards for the client computer. How is this technology different than what is available though ASP? Web Forms are similar to Windows Forms in that they provide properties, methods, and events for the controls that are placed onto them. Besides making it difficult to maintain your transactional integrity, Response. Sure, there are workarounds, but they're difficult. Redirect necessitates a round trip to the client, which, on high-volume sites, causes scalability problems. How can you provide an alternating color scheme in a Repeater control?What type of code (server or client) is found in a Code-Behind class? Should validation (such as did the user enter a real date) occur server-side or client-side? Client-side validation because there is no need to request a server-side date when you could obtain a date from the client machine. However, these UI elements render themselves in the appropriate markup language required by the request, for example HTML. NET then you will also get the familiar drag-and-drop interface used to create your UI for your Web application. Alternating Item Template Like the Item Template element, but rendered for every other row (alternating items) in the Repeater control.

Net provides a cache object for eg: cache["States"] = ds States; What do you mean by authentication and authorization? NET Framework SDK, open the file containing the code you want to debug, and set your breakpoints. (If "aspnet_wp.exe" doesn't appear in the list then check the "Show system processes" box.) Click the "Attach" button to attach to "aspnet_wp.exe" and begin debugging. The controls can bubble up their event handlers, allowing the main Data Grid event handler to take care of its constituents. NET function executed on Mouse Over over a certain button. It's the Attributes property, the Add function of that property. Caching Output Caching: Caches the dynamic output generated by a request. Go back to Dbg Clr, choose "Debug Processes" from the Tools menu, and select "aspnet_wp.exe" from the list of processes.
Validation controls perform input checking in server code. One, it's unlikely that two requests from the same user will overlap. NET locks down session state during request processing so that two threads can't touch it at once. If I update session state then should I lock it, too? By locking application state before updating it and unlocking it afterwards, you ensure that another request being processed on another thread doesn't read application state at exactly the wrong time and see an inconsistent view of it. After Authentication a user will be verified for performing the various tasks, It access is limited it is known as authorization. NET, contains entries that map ASAX files, CONFIG files, and selected other file types to an HTTP handler named Http Forbidden Handler, which fails attempts to retrieve the associated file. Register Startup Script is for returning blocks of client scripts, not packaged in functions. For caching the entire page the page should have Output Cache directive. Authentication is the process of validating a user on the credentials (username and word) and authorization performs after authentication. Note: A few of the references are were taken from other sites/sources. NET application that wasn't written with Visual Studio. Be sure to enable debugging in the ASPX file before debugging it with Dbg Clr. NET to build debug executables by placing a: section of Machine.config, which holds the master configuration settings for ASP. Register Client Script Block is for returning blocks of client-side script containing functions.
