I have 6 arguments. The first is the only one shown in the wizard. The remaining 5 use MonitorArgument and the Evaluator (ExpressionEvaluatorValueProvider).

The input in the wizard is very slow taking a second or two after each character typed. is there a faster implementation of Evaluator or a better ValueProvider to use for simple string formatting?

Here are the specifics:

<Argument Name="ViewName" Required="true">
<Converter Type="Microsoft.Practices.GuidanceAutomation.SmartClient.Converters.TypeNameValidator, SmartClientDevelopment"/>
</Argument>
<Argument Name="ViewTargetFile">
<ValueProvider Type="Evaluator" Expression="$(ViewName)View.cs">
<MonitorArgument Name="ViewName" />
</ValueProvider>
</Argument>
<Argument Name="ViewDesignerTargetFile">
<ValueProvider Type="Evaluator" Expression="$(ViewName)View.Designer.cs">
<MonitorArgument Name="ViewName" />
</ValueProvider>
</Argument>
<Argument Name="ViewInterfaceTargetFile">
<ValueProvider Type="Evaluator" Expression="$(ViewName)ViewInterface.cs">
<MonitorArgument Name="ViewName" />
</ValueProvider>
</Argument>
<Argument Name="ViewPresenterTargetFile">
<ValueProvider Type="Evaluator" Expression="$(ViewName)Presenter.cs">
<MonitorArgument Name="ViewName" />
</ValueProvider>
</Argument>
<Argument Name="WorkItemControllerTargetFile">
<ValueProvider Type="Evaluator" Expression="$(ViewName)WorkItemController.cs">
<MonitorArgument Name="ViewName" />
</ValueProvider>
</Argument>

<Wizard xmlns="http://schemas.microsoft.com/pag/gax-wizards" SchemaVersion="1.0">
<Pages>
<Page>
<Title>Adds a new View</Title>
<Fields>
<Field ValueName="ViewName" Label="View Name:" InvalidValueMessage="Invalid name"/>
</Fields>
</Page>
</Pages>
</Wizard>

That worked. Thanks for the clarification. I had tried the Stage="OnBeforeActions" but didn't realize that I then didn't need the MonitorArgument. Makes sense now.
