How to Use Page Navigation
Not all page navigation scenarios are initiated through hyperlinks on the client. Client-side page redirects or navigations can also be initiated from the server by an ASP.NET page developer by calling the Response.Redirect(url) method. This is typically done when server-side validation is required on some client input before the navigation actually takes place.
The following sample demonstrates how to use the Response.Redirect method to pass parameters to another target page. It also demonstrates how to easily get access to these parameters from the target page.

How To Use Page Navigation in ASP.Net
Page navigation among multiple pages is a common scenario in virtually all Web applications. The following sample demonstrates how to use the

Event handlers provide a clean way for page developers to structure logic within an ASP.NET page. For example, the following sample demonstrates how to wire and handle four button events on a single page.

ASP.NET server controls can optionally expose and raise server events, which can be handled by page developers. A page developer may accomplish this by declaratively wiring an event to a control (where the attribute name of an event wireup indicates the event name and the attribute value indicates the name of a method to call). For example, the following code example demonstrates how to wire an OnClick event to a button control.

You can programmatically identify an individual ASP.NET server control within a page by providing it with an id attribute. You can use this id reference to programmatically manipulate the server control's object model at run time. For example, the following sample demonstrates how a page developer could programmatically set an

Introduction
ASP.NET server controls are identified within a page using declarative tags that contain a runat="server" attribute. The following example declares three

Handling Server Control Events
Each ASP.NET server control is capable of exposing an object model containing properties, methods, and events. ASP.NET developers can use this object model to cleanly modify and interact with the page.
The following example demonstrates how an ASP.NET page developer can handle the OnClick event from the
This simple sample is functionally equivalent to the "Intro3" sample demonstrated earlier in this section. Note, however, how much cleaner and easier the code is in this new server-control-based version. As we will see later in the tutorial, the ASP.NET page Framework also exposes a variety of page-level events that you can handle to write code to execute a specific time during the processing of the page. Examples of these events are Page_Load and Page_Render.
