The controls that support single-value data binding allow you to bind some of their properties to a data binding expression. This expression is entered in the .aspx markup portion of the page (not the code-behind field) and enclosed between the <%# and %> delimiters. Here s an example: <%# expression_goes_here %> This may look like a script block, but it isn t. If you try to write any code inside this tag, you will receive an error. The only thing you can add is valid data binding expressions. For example, if you have a public or protected variable on your page named EmployeeName, you could write the following: <%# EmployeeName %> To evaluate a data binding expression such as this, you must call the Page.DataBind() method in your code. When you call DataBind(), ASP.NET will examine all the expressions on your page and replace them with the corresponding value (in this case, the current value that s defined for the EmployeeName variable). If you forget to call the DataBind() method, the data binding expression won t be filled in instead, it just gets tossed away when your page is rendered to HTML. The source for single-value data binding can include the value of a property, member variable, or return value of a function (as long as the property, member variable, or function has an accessibility of protected or public). It can also be any other expression that can be evaluated at runtime, such as a reference to another control s property, a calculation using operators and literal values, and so on. The following data binding expressions are all valid: <%# <%# <%# <%# GetUserName() %> 1 + (2 * 20) %> "John " + "Smith" %> Request.Browser.Browser %>

If you have an existing web application created with Visual Studio .NET 2002 or 2003, you can open the project or solution file using the File Open Project command. When you do, Visual Studio begins the Conversion Wizard. The Conversion Wizard is exceedingly simple. It prompts you to choose whether to create a backup and, if so, where it should be placed (see Figure 2-3). If this is your only copy of the application, a backup is a good idea in case some aspects of your application can t be converted successfully. Otherwise, you can skip this option.

For this to work, the DatabaseComponent.EmployeeDB class must exist in the App_Code folder or be compiled in an assembly in the Bin folder.

You can place your data binding expressions just about anywhere on the page, but usually you ll assign a data binding expression to a property in the control tag Here s an example page that uses several data binding expressions: <html> <body> <form method=post runat="server"> <asp:Image ID="image1" runat="server" ImageUrl='<%# FilePath %>' /><br /> <asp:Label ID="label1" runat="server" Text='<%# FilePath %>' /><br /> <asp:TextBox ID="textBox1" runat="server" Text='<%# GetFilePath() %>' /><br /> <asp:HyperLink ID="hyperLink1" runat="server" NavigateUrl='<%# LogoPathValue %>' Font-Bold="True" Text="Show logo" /> <br /> <input type="hidden" ID="LogoPath" runat="server" value="apressgif"> <b><%# FilePath %></b><br /> <img src="<%# GetFilePath() %>"> </form> </body> </html> As you can see, not only can you bind the Text property of a Label and a TextBox, but you can also use other properties such as the ImageUrl of an Image, the NavigateUrl property of a HyperLink, and even the src attribute of a static HTML <img> tag.

When you click Finish, Visual Studio performs an in-place conversion. The conversion tool is fairly aggressive, and it attempts to convert every web page to use Visual Studio s new code-behind model. Any errors and warnings are added to a conversion log, which you can display when the conversion is complete. In a typical website, the conversion operation runs without any errors but generates a long list of warnings. These inform you when Visual Studio removes precompiled files, changes pages to use automatic event wire-up, and modifies the accessibility of event handlers (switching them from private to protected). All of these changes are minor modifications designed to apply the new coding model, which is described in the section The Coding Model later in this chapter. Figure 2-4 shows a sample log.

Once you ve attached the ObjectDataSource to a class, the next step is to point it to the methods it can use to select and update records. The ObjectDataSource defines SelectMethod, DeleteMethod, UpdateMethod, and InsertMethod properties that you use to link your data access class to various tasks. Each property takes the name of the method in the data access class. In this example, you simply need to enable querying, so you need to set the SelectMethod property: <asp:ObjectDataSource ID="sourceEmployees" runat="server" TypeName="DatabaseComponent.EmployeeDB" SelectMethod="GetEmployees" /> Remember, the GetEmployees() method returns an array of EmployeeDetails objects. These objects fit the criteria of the ObjectDataSource they provide all the appropriate record data through public properties. Once you ve set up the ObjectDataSource, you can bind your web-page controls in the same way you do with the SqlDataSource. You can even use the same drop-down lists in the Properties window, provided you click the Refresh Schema link in the ObjectDataSource smart tag first. When you click Refresh Schema, Visual Studio retrieves the property names and data types by reflecting on the EmployeeDetails class.
