The visual designer uses the RouteValueExpressionEditor class together with the RouteValueExpressionEditorSheet class to select the individual properties of a RouteValue expression, and to combine the selected expression property values into a RouteValue expression.

The RouteValueExpressionEditor.GetExpressionEditorSheet method returns a RouteValueExpressionEditorSheet object. In the expressions dialog box, when you select a control property and bind it to a RouteValue expression, the visual designer calls the GetExpressionEditorSheet method. The visual designer uses the returned RouteValueExpressionEditorSheet object to prompt for the RouteValue property. Once the property is selected, the visual designer calls the GetExpression method to create a RouteValue expression string.

The P:System.Web.UI.Design.RouteUrlExpressionEditorSheet.RouteValue property must be specified in order to create a RouteValue expression string.
