Assembly:  System.Design (in System.Design.dll)

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public class SqlDataSourceConnectionStringEditor : ConnectionStringEditor

The SqlDataSourceConnectionStringEditor class is a UITypeEditor object that can be used at design time to select and edit a connection string expression and to assign the expression to a control property. The SqlDataSource object uses the SqlDataSourceConnectionStringEditor class at design time to set the value of the ConnectionString property.

If an IDataEnvironment interface is available, connection strings are retrieved from the data services of the visual designer. If an IDataEnvironment interface is not available, a modal dialog box is shown to allow editing of the connection string.

Use the EditorAttribute attribute to associate the SqlDataSourceConnectionStringEditor with a property. When the associated property is edited on the design surface, the designer host calls the EditValue method. The EditValue method displays a user interface for building the connection string expression and returns the connection string that is selected by the user. The GetEditStyle method indicates the display style of the user interface.
