Examples

The following XAML snippet shows how to use the ArgumentToExpressionConverter in a custom activity designer that uses an ExpressionTextBox.

<sapv:ExpressionTextBox   
    Expression="{Binding Path=ModelItem.SampleValue,   
                         Mode=TwoWay,   
                         Converter={StaticResource ArgumentToExpressionConverter},   
                         ConverterParameter=In }"  
    ExpressionType="s:String"  
    OwnerActivity="{Binding Path=ModelItem}"  
   />

This converter can also be used imperatively; however, this usage is not recommended.
