CIS 375—Web App Dev II ASP.NET 3 Working With Server Controls

2 Declaring Server Controls ASP.NET server controls are identified within a page using declarative _____ that contain a runat="server" attribute. The following example declares three server controls and customizes the text and style properties of each one individually. VB Controls1.aspx [Run Sample] | [View Source]Run SampleView Source

3 Manipulating Server Controls You can identify an individual ASP.NET server control within a page by providing it with an ___ attribute. You can use this id reference to manipulate the server control's _______ model at run time. For example, the following sample demonstrates how a page developer could set an control's Text property within the Page_Load event.

4 Handling Control Action Events ASP.NET server controls can optionally expose and _______ server events, which can be handled by page developers. A page developer may accomplish this by declaratively _______ 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 _________ to call. For example, the following example demonstrates how to wire an OnClick event to a button control. VB Controls3.aspx [Run Sample] | [View Source]Run SampleView Source

5 Performing Page Navigation (Scenario 1) Page navigation among multiple pages is a common scenario in virtually all Web applications. The following sample demonstrates how to use the control to navigate to another page (passing custom query string ___________ along the way). The sample then demonstrates how to easily get access to these query string parameters from the ________ page.

6 Performing Page Navigation (Scenario 2) Not all page navigation scenarios are initiated through hyperlinks on the ________. Client-side page redirects can also be initiated from the server with Response.Redirect(url). This is typically done when server-side ___________ is required on some client input before navigation. The following demonstrates how to use Response.Redirect to pass parameters to another target page. It also demonstrates how to easily get access to these parameters from the target page.
