If you look back at the markup in Listing 11-1, you ll see that lblQuote is contained within the UpdatePanel control s <ContentTemplate> setting. Because the ScriptManager control has enabled partial rendering and because the label is within the UpdatePanel control, this enables the Ajax-style update of the page whenever lblQuote has its text property changed. You can see that there is no explicit coding for a partial-page update. Everything is handled under the hood by the Atlas runtime. You concentrate on building your application, and by wrapping standard ASP .NET controls with an <UpdatePanel>, you can enable the asynchronous functionality. You ll now see what happens when you click the ellipsis button in this page to render the extended price information. You can see from the markup that the button is called btnMore and that it has a click event handler called btnMore_Click. Here s a snippet from the markup as a reminder: <asp:Button ID="btnMore" runat="server" Text="..." OnClick="btnMore_Click" CausesValidation="False" /> This btnMore_Click event handler looks like this: protected void btnMore_Click(object sender, EventArgs e) { GetExtendedQuote(TextBox1.Text); } It simply calls a helper function, passing it the contents of the text box containing the ticker information entered by the user. This function looks like this: private void GetExtendedQuote(string strTicker) { companyInfo.CompanyInfoService svc = new companyInfo.CompanyInfoService(); companyInfo.CompanyInfoResult rslt = svc.doCompanyInfo("anything", "anything", strTicker); StringBuilder theHTML = new StringBuilder(); theHTML.Append("<table width='100%' cellspacing='0' cellpadding='0' style='border-width: 0'>"); theHTML.Append("<tr><td width='40%'>"); theHTML.Append("Bid "); theHTML.Append("</td><td width='40%'>"); theHTML.Append(rslt.bid); theHTML.Append("</td></tr>"); theHTML.Append("<tr><td width='40%'>"); theHTML.Append("Ask "); theHTML.Append("</td><td width='40%'>"); theHTML.Append(rslt.ask); theHTML.Append("</td></tr>");

We ll cover attributes in 24, but it s worth mentioning the Flags attribute here. An attribute appears as a string between square brackets placed on the line above a class declaration. The attribute does not change the calculations at all. It does, however, provide several convenient features. First, it informs the compiler, object browsers, and other tools looking at the code that the members of the enum are meant to be combined as bit flags, rather than used only as separate values. This allows the browsers to interpret variables of the enum type more appropriately. Second, it allows the ToString method of an enum to provide more appropriate formatting for the values of bit flags. The ToString method takes an enum value and compares it to the values of the constant members of the enum. If it matches one of the members, ToString returns the string name of the member. Suppose, for example, that you have used the enum declaration for CardDeckSettings (given in the preceding code), and have not used the Flags attribute. The first line of the following code creates a variable (named ops) of the enum type, and sets the value of a single flag bit. The second line uses ToString to get the string name of the member represented by that value. CardDeckSettings ops = CardDeckSettings.FancyNumbers; Console.WriteLine( ops.ToString() ); This code produces the following output: // Set the bit flag. // Print its name.

For example, this XAML defines a Save button: <Button Command="ApplicationCommandsSave" CommandTarget="{Binding Source={StaticResource Project}, Path=CommandManager, BindsDirectlyToSource=True}" HorizontalAlignment="Left" IsDefault="True">Save</Button> Notice how the CommandTarget property is specified The Source is a CslaDataProvider control, but the binding path indicates that the command should be routed to the data provider control s CommandManager property, which is an instance of CslaDataProviderCommandManager In CslaDataProviderCommandManager is a SaveCommand() method that is invoked by the WPF commanding infrastructure when the Button control is clicked: Private Shared Sub SaveCommand(ByVal target As Object, _ ByVal e As ExecutedRoutedEventArgs) Dim ctl = TryCast(target, CslaDataProviderCommandManager) If ctl IsNot Nothing AndAlso ctlProvider IsNot Nothing Then ctlProviderSave() End If End Sub The CslaDataProviderCommandManager has a Provider property, which is a reference to its parent CslaDataProvider control You can see how this code delegates the call to its parent: ctlProvider.
