  1. 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 <asp:label runat="server"> server controls and customizes the text and style properties of each one individually. • VB Controls1.aspx [Run Sample] | [View 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 <asp:label runat="server"> control's Text property within the Page_Load event. • VB Controls2.aspx [Run Sample] | [View Source]

  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]

  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 <asp:hyperlink runat=server> 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. • VB Controls6.aspx [Run Sample] | [View Source]
