The OPC Controls ComboBox component performs exactly like the standard ComboBox 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 ComboBox select the OPCControlsComboBox component from the ToolBox and place it on any Windows Form of your choice.

OPC Controls ComboBox 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 SetValueOPCSystems property to enable the ability to write to a Tag Parameter when the ComboBox is clicked.  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 ComboBox is clicked.

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