PI-ServerPickList Control



A PI-ServerPickList control consists of a dropdown list of all PI servers in the Known Servers Table. All servers displayed above the line are connected; all servers displayed below the line are disconnected. If there is only one server in the list, the line is not displayed. You may configure the control to establish a connection to the server when it is selected.

When to Use This Control

This control allows a user to select and optionally connect to a PI Server using a minimum amount of screen real estate. It is a fundamental component of most forms that require the user to specify which PI server to access.


How to Use This Control

Site this control on a form. The SelectedServer property should be initialized otherwise the default server will be used. Also use the SelectedServer property to retrieve the selection. The Click event is fired when a new selection is made.


Configuration Options

Automatic Login

You may set the ConnectOnSelection property to automatically establish a connection to a server when it is selected. The default user name and no password is used to establish the connection; if it fails, the PI-Login dialog is displayed to allow the user to enter a user name and password.
