The first step of creating a WebPart page is to create an .aspx page in your solution. You don t have to add a special item just add a simple web form to your project. Afterward, you can structure the basic layout of your page as you d like. The following example uses a simple HTML table to structure the page with a main center area, a configuration area on the left, and a simple information area on the right: <form id="form1" runat="server"> <div> <table width="100%"> <tr valign="middle" bgcolor="#00ccff"> <td colspan="2"> <span style="font-size: 16pt; font-family: Verdana"> <strong>Welcome to web part pages!</strong> </span> </td> <td>Menu</td> </tr> <tr valign="top"> <td width="20%"> </td> <td style="width: 60%"> </td> <td width="20%"> </td> </tr> </table> </div> </form> The first table row is just a simple header for the application. Within the second row, the table contains three columns: the left one will be used as a column for configuration controls (such as a control for selecting available WebParts), the center column will be used for displaying the main information, and the right column will be used for little WebParts with additional information. Notice that the first row includes a second column for a menu; you will use this menu later for switching between the modes of the page (for example, from the Browse mode that merely displays information to the Design mode that allows the user to move WebParts from one zone to another). You can see the page layout in Figure 30-2.

Now recall that the ComboBox has a collection of ComboBoxItems If you were to view the generated XAML, you d see the following definition: <ComboBox x:Name="comboColors" Width="100" SelectionChanged="ColorChanged"> <ComboBoxItem Content="Red"/> <ComboBoxItem Content="Green"/> <ComboBoxItem Content="Blue"/> </ComboBox> When you call SelectedItem, you grab the selected ComboBoxItem, which is stored as a general Object Once you cast the Object as a ComboBoxItem, you pluck out the value of the Content, which will be the string Red, Green, or Blue This string is then converted to a Color object using the handy ColorConverter utility class Now run your program again You should be able to change between colors as you render your image Note that the ComboBox and ListBox controls can contain complex content as well, rather than a list of text data.

After you have created the web page s design, you can continue adding the first WebPart controls to your page. These controls are summarized in the WebParts section of Visual Studio s Toolbox. For this example, the first control to add at the bottom of your page is the WebPartManager control. The WebPartManager works with all the zones added to the web page and knows about all the WebParts available for the page. It furthermore manages the personalization and makes sure the web page is customized for the currently logged-on user. The following code snippet shows the modified portion of the page code: <form id="form1" runat="server"> <div> <asp:WebPartManager runat="server" ID="MyPartManager" /> <table width="100%"> ... </table> </div> </form> The WebPartManager also throws events you can catch in your application to perform actions when the user adds or deletes a WebPart or when a WebPart communicates with another WebPart. (You will learn more about WebPart communication later in the Connecting WebParts section.) After you have added the WebPartManager to the page, you can add customizable sections to your WebPart. These sections are called WebPartZones, and every zone can contain as much WebParts as the user wants. With the WebPartZone controls added, the complete code looks as follows: <form id="form1" runat="server"> <div> <asp:WebPartManager runat="server" ID="MyPartManager" /> <table width="100%"> <tr valign="middle" bgcolor="#00ccff"> <td colspan="2">

You can get a sense of some of the things that are possible by opening the XAML editor for your window and changing the definition of your ComboBox so it contains a set of <StackPanel> elements, each of which contains an <Ellipse> and a <Label> (notice that the Width of the ComboBox is 200): <ComboBox x:Name="comboColors" Width="200" SelectionChanged="ColorChanged"> <StackPanel Orientation ="Horizontal" Tag="Red"> <Ellipse Fill ="Red" Height ="50" Width ="50"/> <Label FontSize ="20" HorizontalAlignment="Center" VerticalAlignment="Center" Content="Red"/> </StackPanel> <StackPanel Orientation ="Horizontal" Tag="Green"> <Ellipse Fill ="Green" Height ="50" Width ="50"/> <Label FontSize ="20" HorizontalAlignment="Center" VerticalAlignment="Center" Content="Green"/> </StackPanel> <StackPanel Orientation ="Horizontal" Tag="Blue"> <Ellipse Fill ="Blue" Height ="50" Width ="50"/> <Label FontSize ="20" HorizontalAlignment="Center" VerticalAlignment="Center" Content="Blue"/> </StackPanel> </ComboBox> Notice that each StackPanel assigns a value to its Tag property, which is a simple, fast, and convenient way to discover which stack of items has been selected by the user (there are better ways to do this, but this will do for now).
