Asp net life cycle

In the application domain, an instance of the HostingEnvironment class is created, which provides access to information about the application, such as the name of the folder where the application is stored.

All requests can be configured to take advantage of ASP. The main differences between both of them are: Although both Init and Load recursively occur on each control, they happen in reverse order. Once the environment is created, the request is processed through a series of events which is processed by using modules, handlers and page objects.

If you set control property at this stage, its value might be overwritten in the next event.

ASP.NET Page Life Cycle Overview

Use this event to set text in the control that explains the problem or to direct the user to a different page. It checks the IsPostBack property and determines whether the page is a postback. This is raised after the control state and view state have been saved for the page and for all controls.

The Unload event is raised after the page has been fully rendered, sent to the client, and is ready to be discarded. The Load event of individual controls occurs after the Load event of the page.

However, in IIS 7. If you attempt to call a method such as the Response. This event marks the beginning of the process that binds the control to the data. To fill the list of officers, you would bind the ListBox control to a data source control such as SqlDataSource that retrieves the company officer data using the company ID in a query.

Raised if authentication was not successful. These stages are represented by the RequestNotification enumeration. NET page is processed.

ASP.NET Application and Page Life Cycle

View state tracking enables controls to persist any values that are programmatically added to the ViewState collection. This event marks the beginning of the process that binds the control to the data. Set the Theme property dynamically.

Set master page dynamically. This enables you to take advantage of ASP. OnSaveStateComplete Raised after view state and control state have been saved for the page and for all controls.

PreRenderComplete - As the PreRender event is recursively fired for all child controls, this event ensures the completion of the pre-rendering phase. Before this event occurs, ViewState has been saved for the page and for all controls.

You can download the same from here or else you can catch me on my daily free training here. Init - Init event initializes the control property and the control tree is built.

This includes before any server processing occurs for the request, after all server processing has occurred, or anywhere in between. For example, Asp net life cycle you have a GridView control that displays a company record in each row, and it displays a list of the company officers in a ListBox control.

If you want to inject logic in the events of ASP. You may also call Validate and check the value of IsValid in this method.

Both native-code and managed-code modules can be configured at the Web server, Web site, or Web application level. After that, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page.

To help you understand the relationship between the page life cycle and data binding events, the following table lists data-related events in data-bound controls such as the GridViewDetailsViewand FormView controls.

NET Environment Step 1: Once the hosting environment is created, the necessary core ASP.The topics in this section provide background information about how processes pages to produce dynamic output. This includes information about how the application itself and individual pages are instantiated and processed, and information about how compiles pages dynamically.

When an page runs, the page goes through a life cycle in which it performs a series of processing steps. These include initialization, instantiating controls, restoring and maintaining state, running event handler code, and rendering.

ASP.NET Life Cycle

There 10 events in page life cycle and the sequence is: Init,Load view state,PostBackdata,Load,Validate,Event,Pre-render,Save view state,Render and Unload. Below is pictorial view of Page life cycle with what kind of code is. The application life cycle can be extended with modules that implement the IHttpModule interface.

Modules that implement the IHttpModule interface are managed-code modules. The integrated pipeline of and IIS is also extensible through native-code modules, which are not discussed in this topic. Page Life Cycle Events At each stage of the page life cycle, the page raises some events, which could be coded. An event handler is basically a function or subroutine, bound to the event, using declarative attributes such as Onclick or handle.
