Custom Modal Dialog Editor for Adapter Configuration

The code for the custom editor shows an editor derived from the System.Drawing.Design.UITypeEditor class that displays a modal pop-up dialog box for entering a password. The GetEditStyle method override returns UIEditorEditStyle.Modal to indicate a modal form subcontrol. The service method ShowDialog manages the control created with CreatePassword. ShowDialog returns a DialogResult that is handled in the usual way (for example, a switch statement) with the DialogResult.OK case changing value only.

The following code is the class definition for the custom modal editor:
