Parameters
- target
The object containing the expression.
- entry
The object that represents information about the property bound to by the expression.
- parsedData
The object containing parsed data as returned by ParseExpression.
- context
Contextual information for the evaluation of the expression.
Return Value
An object that represents the evaluated expression; otherwise, a null reference (Nothing in Visual Basic) if the inheritor does not implement EvaluateExpression.If you want your ExpressionBuilder object to be active on a page that supports the no-compile feature, you can override the EvaluateExpression method and the SupportsEvaluate property. The EvaluateExpression method should return the evaluation of the current expression.
Notes to Inheritors: If you override the EvaluateExpression method, you must also override the SupportsEvaluate property.Windows 98, Windows Server 2000 SP4, Windows Millennium Edition, Windows Server 2003, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP SP2, Windows XP Starter Edition
