As well stocked as the five command classes (ApplicationCommands, NavigationCommands, EditingCommands, ComponentCommands, and MediaCommands) are, they obviously can t provide everything your application might need. Fortunately, it s easy to define your own custom commands. All you need to do is instantiate a new RoutedUICommand object. The RoutedUICommand class provides several constructors. You can create a RoutedUICommand with no additional information, but you ll almost always want to supply the command name, the command text, and the owning type. In addition, you may want to supply a keyboard shortcut for the InputGestures collection. The best design is to follow the example of the WPF libraries and expose your custom commands through static properties. Here s an example with a command named Requery: public class DataCommands { private static RoutedUICommand requery; static DataCommands() { // Initialize the command. InputGestureCollection inputs = new InputGestureCollection(); inputs.Add(new KeyGesture(Key.R, ModifierKeys.Control, "Ctrl+R")); requery = new RoutedUICommand( "Requery", "Requery", typeof(DataCommands), inputs); } public static RoutedUICommand Requery { get { return requery; } } }

Tip You can also modify the RoutedCommand.InputGestures collection of an existing command for example,

by removing existing key bindings or adding new ones. You can even add mouse bindings, so a command is triggered when a combination of a mouse button and modifier key is pressed (although, in this case, you ll want to place the command binding on just the element where the mouse handling should come into effect).

With the data contracts defined, you can now define the service contracts. Place these service contracts in a new project titled ServiceContracts: 1. Right-click the solution, and select Add New Project. 2. Select Class Library, and name the library ServiceContracts. 3. Right-click the project, and select Add Reference. 4. On the Browse tab, navigate to RSS.DLL, and click OK. 5. Right-click the project, and select Add Reference.

Once you ve defined a command, you can use it in your command bindings in the same way as any of the ready-made commands that are provided by WPF. However, there s one twist. If you want to use your command in XAML, you need to first map your .NET namespace to an XML namespace. For example, if your class is in a namespace named Commands (the default for a project named Commands), you would add this namespace mapping: xmlns:local="clr-namespace:Commands" In this example, local is chosen as the namespace alias. You can use any alias you want, as long as you are consistent in your XAML file. Now you can access your command through the local namespace: <CommandBinding Command="local:DataCommands.Requery" Executed="RequeryCommand_Executed"></CommandBinding> Here s a complete example of a simple window that includes a button that triggers the Requery command: <Window x:Class="Commands.CustomCommand" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="CustomCommand" Height="300" Width="300"> <Window.CommandBindings> <CommandBinding Command="local:DataCommands.Requery" Executed="RequeryCommand_Executed"></CommandBinding> </Window.CommandBindings> <Button Margin="5" Command="local:DataCommands.Requery">Requery</Button> </Window> To complete this example, you simply need to implement the RequeryCommand_Executed() event handler in your code. Optionally, you can also use the CanExecute event to selectively enable or disable this command.

Tip When using custom commands, you may need to call the static CommandManager.InvalidateRequerySuggested()

method to tell WPF to reevaluate the state of your command. WPF will then trigger the CanExecute event and update any command sources that use that command.

6. On the Browse tab, navigate to OPML.DLL, and click OK. 7. Right-click the project, and select Add Reference. 8. On the .NET tab, select System.ServiceModel, and click OK.

One of the key ideas in the WPF command model is scope. Although there is exactly one copy of every command, the effect of using the command varies depending on where it s triggered. For example, if you have two text boxes, they both support the Cut, Copy, and Paste commands, but the operation happens only in the text box that currently has focus. You haven t yet learned how to do this with the commands that you wire up yourself. For example, imagine you create a window with space for two documents, as shown in Figure 9-7.
