Validating length of textbox in datagrid

The latter one allows you to write formatted output. Init () When the page is instantiated, Load() when the page is loaded into server memory; Pre Render() for the brief moment before the page is displayed to the user as HTML and Unload() when the page finishes loading. Are concurrent accesses by multiple requests executing on multiple threads a concern with session state? If I update session state then should I lock it, too? 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. When you have a complex control, like Data Grid, writing an event processing routine for each object (cell, button, row and so on) is quite tedious. Add("on Mouse Over","some Client Code();") What data type does the Range Validator control support? In the context of a web application, caching retains the pages or data across HTTP requests and reuses them without the expense of recreating them. NET has 3 kinds of caching, strategies Output, Caching Fragment and Caching Data. Page Where do you store the information about the user's locale? You can modify it by editing Machine.config or including a section in a local Web.config file. In other words, code that's to execute when the page is loaded. 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.Explain the differences between Server-side and Client-side code?Server-side scripting means that all the script will be executed by the server and interpreted as needed.

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?

The purpose of this article is to consolidate most of the study material related to . It defaults to false but should be set to true in any ASPX file that creates apartment-threaded COM objects; that is, COM objects registered with Threading Model=Apartment.

What does Asp Compat="true" mean and when should I use it?

Persistent authentication cookies do not time-out and therefore are a more serious security threat if stolen. Note that VSDISCO files are disabled in the release version of ASP. You can reenable them by uncommenting the line in the section of Machine.config that maps *.vsdisco to System. Is it possible to prevent a browser from caching an ASPX page?

NET can detect when a form is requested for the first time versus when the form is posted (sent to the server), that allows you to program accordingly. Custom controls A control authored by a user or a third-party software vendor that does not belong to the . This is a generic term that includes user controls. So a stolen session cookie can only be used in replay attacks as long as the ticket inside the cookie is valid. You can change that by modifying the timeout attribute accompanying the element in the Machine.config or a local Web.config file. Mail Message and Smtp Mail are classes defined in the . A client who requests a VSDISCO file gets back what appears to be a static DISCO document. However, Microsoft is actively discouraging the use of VSDISCO files because they could represent a threat to Web server security.

First, it makes intrinsic ASP objects available to the COM components by placing unmanaged wrappers around the equivalent ASP. Second, it improves the performance of calls that the page places to apartment-threaded COM objects by ensuring that the page (actually, the thread that processes the request for the page) and the COM objects it creates share an apartment. NET request threads into single-threaded apartments (STAs).
