IDtsDesignerUtilitiesService.EditPropertyExpression Method

Displays the Expression Builder dialog box that lets the end user use the Integration Services expression language to create and test a property expression.

Namespace:  Microsoft.SqlServer.Dts.Design
Assembly:  Microsoft.SqlServer.Dts.Design (in Microsoft.SqlServer.Dts.Design.dll)

bool EditPropertyExpression(
	IWin32Window parentWindow,
	DtsContainer dtsContainer,
	IDTSPropertiesProvider property,
	string propertyName
)

Parameters

parentWindow
Type: IWin32Window
The IWin32Window handle to the Windows form from which the Expression Builder dialog box is invoked.
dtsContainer
Type: Microsoft.SqlServer.Dts.Runtime.DtsContainer
The DtsContainer that defines the scope for package variables that can be used in the expression.
property
Type: Microsoft.SqlServer.Dts.Runtime.IDTSPropertiesProvider
The IDTSPropertiesProvider that represents the property to which the expression is assigned.
propertyName
Type: String
The name of the property to which the expression is assigned.

Return Value

Type: Boolean
true if the expression has changed; otherwise, false.

When the expression is a property expression, the EditPropertyExpression method is simpler to use than the EditExpression method. The EditPropertyExpression method determines the return type of the expression from the data type of the property and assigns the expression to the property for you. However, you can also use the EditExpression method whenever you want to let the user create or modify an expression.
