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

OPC Controls TextBox 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 TextOPCSystemsSendValueOnEnter property to enable the ability to write to a Tag Parameter when the Enter key is selected with the focus of the TextBox.  If the Tag Parameter is assigned to an OPC Item as a source the OPC Item will be written to with the value entered when the OPC Controls TextBox has received the Enter key event.

Use the TextOPCSystemsDisableUpdateWithFocus property to disable automatic updates to the TextBox when the TextBox has focus.  When the focus is lost the latest received value will be updated to the Text property.

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

BackColor
