The OPC Web Controls DropDownList component performs exactly like the standard WebForms DropDownList component with additional properties to automatically update from any OPC Systems Tag Parameter, and to set any OPC Systems Tag Parameter with a click without any programming.  The OPC Systems Properties are design mode accessible and allow for browsing any local or remote OPC Systems Service.  For additional description of all properties and methods refer to the OPCWebControls Help file.
