The OPC Controls VScrollBar component performs exactly like the standard VScrollBar component with additional properties to automatically update from any OPC Systems Tag Parameter.  For programmatic help refer to the OPCControls Help file.

To add an OPC Controls VScrollBar select the OPCControlsVScrollBar component from the ToolBox and place it on any Windows Form of your choice.

OPC Controls VScrollBar Properties

Refer to OPCControls help for all properties and members of the OPC Controls.NET components.  All properties can be assigned in code; however no programming is required to use the properties.

Use the ValueOPCSystemsSetValue property to enable the ability to write to a Tag Parameter when the VScrollBar is scrolled.  If the Tag Parameter is assigned to an OPC Item as a source the OPC Item will be written to with the value specified when the OPC Controls VScrollBar is scrolled.

The following properties can automatically be set by OPC Systems Tag values.
