ConnectionStringsExpressionEditor Class

Provides properties and methods for selecting a data connection expression that is associated with a control property at design time.


Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

public class ConnectionStringsExpressionEditor : ExpressionEditor

The ConnectionStringsExpressionEditor type exposes the following members.

Public methodConnectionStringsExpressionEditorInitializes a new instance of the ConnectionStringsExpressionEditor class.

Public propertyExpressionPrefixGets the expression prefix that identifies expression strings that are supported by the expression editor implementation. (Inherited from ExpressionEditor.)

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodEvaluateExpressionEvaluates a connection string expression and provides the design-time value for a control property. (Overrides ExpressionEditor.EvaluateExpression(String, Object, Type, IServiceProvider).)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetExpressionEditorSheetReturns an expression editor sheet for a connection string expression. (Overrides ExpressionEditor.GetExpressionEditorSheet(String, IServiceProvider).)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

A visual designer host, such as Visual Studio 2005, uses the ConnectionStringsExpressionEditor class to select a connection string from the connectionStrings configuration section.

The ConnectionStringsExpressionEditor class is derived from the ExpressionEditor class, and although it is public for technical reasons, there is no advantage in deriving from it.
