ExpressionBuilder.GetCodeExpression Method

When overridden in a derived class, returns code that is used during page execution to obtain the evaluated expression.

Namespace: System.Web.Compilation
Assembly: System.Web (in system.web.dll)

public:
virtual CodeExpression^ GetCodeExpression (
	BoundPropertyEntry^ entry, 
	Object^ parsedData, 
	ExpressionBuilderContext^ context
) abstract
public abstract CodeExpression GetCodeExpression (
	BoundPropertyEntry entry, 
	Object parsedData, 
	ExpressionBuilderContext context
)
public abstract function GetCodeExpression (
	entry : BoundPropertyEntry, 
	parsedData : Object, 
	context : ExpressionBuilderContext
) : CodeExpression
Not applicable.

Parameters

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

A 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.

No code example is currently available or this language may not be supported.
