ExpressionBuilder::GetCodeExpression Method
When overridden in a derived class, returns code that is used during page execution to obtain the evaluated expression.
Assembly: System.Web (in System.Web.dll)
public: virtual CodeExpression^ GetCodeExpression( BoundPropertyEntry^ entry, Object^ parsedData, ExpressionBuilderContext^ context ) abstract
Parameters
- entry
- Type: System.Web.UI::BoundPropertyEntry
The object that represents information about the property bound to by the expression.
- parsedData
- Type: System::Object
The object containing parsed data as returned by ParseExpression.
- context
- Type: System.Web.Compilation::ExpressionBuilderContext
Contextual information for the evaluation of the expression.
Return Value
Type: System.CodeDom::CodeExpressionA CodeExpression that is used for property assignment.
Classes that inherit from the ExpressionBuilder class must implement the GetCodeExpression abstract method.
Notes to Inheritors:If you implement a custom expression builder, you must perform the proper type casting for the control property and return the cast operation in the CodeExpression object.
The following code example demonstrates how to return a CodeExpression object by overriding the GetCodeExpression method.
