You develop a Web application that contains two master pages. You need to dynamically set the master page when a user views pages in the application. What should you do?

Exhibit:

You are creating a composite control for capturing user address information in a Web application. You define a number of properties that the user can set at design time. You need to group these properties in the Properties dialog box. In addition, you need to ensure that when users click on a particular property, they receive a short explanation of that property. The properties are shown in the exhibit.
Which two actions should you perform?
(Each correct answer presents part of the solution. Choose two.)

You create a Web Form that contains a text box named txtDate. You want the text box to allow users to enter any valid date. You need to use an ASP.NET validation control to ensure that only valid date values are submitted to the server. What should you do?

Exhibit:

You create a master page named Parent.master that contains a global header for your Web application. You add a ContentPlaceHolder to Parent.master by using the following code segment.

<asp:ContentPlaceHolder ID="pagebody" runat="server" />

You also create a content page named Article.aspx by using the following code segment.

<%@ Page Language="C#" MasterPageFile="~/navigation.master"%> <asp:Content ContentPlaceHolderID="article" Runat="Server">

Article content to go here

</asp:Content>

You need to create a child master page that
contains the navigation for each section. The users must be able to see the header, the navigation, and the article when they view the page, as shown in the exhibit.
Which code segment should you use?

You create an application. The application processes hundreds of XML documents per minute. The XML documents are validated against inline schemas. You need to load XML documents from the file system and read them as quickly as possible. XML comments must be ignored while reading the XML documents. What should you do?

Your Web site uses custom Themes. Your Web site must support additional Themes based on the user’s company name. The company name is set when a user logs on to the Web site. The company’s Theme name is stored in a variable named ThemeName. You need to use this variable to dynamically set the Web site’s Theme. What should you do?

You are developing a product search page named Search.aspx for Web application that will be integrated into Domain.com’s existing e-Commerce Web site. The Search.aspx page allows customers search for products that match specific criteria. The search criteria are implemented as CheckBox controls. The Search button is implemented as a Button control. You want the CheckBox controls to be cleared when the Search button is clicked. You set the Checked property of each CheckBox to False in the designer.
What should you do next?

You are developing a Web application for Domain.com’s existing Web site. The Web application implements role-based security to allow for the administration and maintenance of the Domain.com Web site. It allows members of the Admins role to administer the Web site, including the databases used by the Web site, while allowing members of the Support role to a maintain the Web site by adding and editing product information. Only members of the Admins role should have access to confidential user information.
