4 . . Right-click in the middle of the Handler Mappings page, and click Add Managed Handler . 5 . . Type in an extension you d like to have mapped to the custom handler, as shown in the following graphic . Then, assign a handler . IIS will look at all the handlers available to your

In the ComposeEmailVew class, an interaction request trigger is defined, and data is bound to the ConfirmExitInteractionRequest property on the view model. When the interaction request is made, a simple pop-up window will be displayed to the user, as shown in the following example.

application (including the ones local to your application) . Select the handler from the drop-down list, give the handler an alias, and you ll be able to surf to that file type to invoke the handler .

The value injected into the placeholder tokens, and the number of tokens used, depends on the type of validator although there are three tokens that are common to all validators The token {0} will be replaced by the value of the object being validated (ensure that you escape this value before you display or use it in order to guard against injection attacks) The token {1} will contain the name of the member that was being validated, if available, and is equivalent to the Key property of the validator The token {2) will contain the value of the Tag property of the validator The remaining tokens depend the on the individual validator type For example, in the case of the Contains Characters validator, the tokens {3} and {4} will contain the characters to check for and the ContainsCharacters value (All or Any).

6 . . Finally, add a blank text file named CustomHandler.cstm to your project . You can use the file with that extension to surf to the handler . 7 . . Surf to the customhandler .cstm resource, and ASP .NET will invoke the custom handler you just created, as shown in this graphic:

XAML <UserControl.Resources> <DataTemplate x:Name="ConfirmExitDialogTemplate"> <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding}"/> </DataTemplate> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <ei:Interaction.Triggers> <prism:InteractionRequestTrigger SourceObject="{Binding ConfirmExitInteractionRequest}"> <prism:PopupChildWindowAction ContentTemplate="{StaticResource ConfirmExitDialogTemplate}"/> </prism:InteractionRequestTrigger> </ei:Interaction.Triggers> ...

Of course, most of this processing could be handled more easily by setting up a Web Form . However, this example shows the flexibility of the ASP .NET handler architecture . It should also give you more appreciation for the Web Form and custom controls machinery in ASP .NET .

In the case of a range validator, such as the String Length validator, the tokens {3} to {6} will contain the values and bound types (Inclusive, Exclusive, or Ignore) for the lower and upper bounds you specify for the validator For example, you may define a String Length validator like this:.

14, Session State, discusses, as its title implies, session state . Session state works automatically in the context of System.Web.UI.Page . However, custom handlers need to turn on the ability to use session state deliberately . The .NET architecture uses an interesting idiom known as marker interfaces . Marker interfaces are empty interfaces (without any methods or properties defined) . Their sole purpose is to signal the runtime about various aspects of the application . For example, the ASP .NET runtime often uses them to turn on and off various features . When the runtime detects a marker interface as part of an object s class hierarchy, the runtime can bring into play certain features . For a handler to use session state, it must have the System.Web.SessionState.IRequiresSessionState interface in its inheritance list . That way the runtime will know to load and store session state at the beginning and end of each request . Listing 19-3 shows a handler with session state enabled .

The ConfirmNavigationRequest method on the ComposeEmailVewModel class is called if the user attempts to navigate while an email is being composed. The implementation of this method invokes the interaction request defined earlier so that the user can confirm or cancel the navigation operation. The following example shows the use of the ConfirmNavigationRequest method.

using using using using using System; System.Collections.Generic; System.Text; System.Web; System.Web.SessionState;

[StringLengthValidator(5, RangeBoundaryType.Inclusive, 20, RangeBoundaryType.Inclusive, MessageTemplate = "{1} must be between {3} and {5} characters.")]

public class HandlerWithSessionState : IHttpHandler, IRequiresSessionState { public void ProcessRequest(HttpContext ctx) { string strData = (string)ctx.Session["SomeSessionData"]; if (String.IsNullOrEmpty(strData)) { strData = "This goes in session state"; ctx.Session["SomeSessionData"] = strData; } ctx.Response.Write("This was in session state: " + strData);
