Attaching a Dynamic List Data Table to a List Box Button
Once you have created a list Box Button, and defined List Data in your NetLinx Code (with Data List
Commands), you are ready to associate the List Data Table to the List Box Button. It is this association
that allows the data in the List Data to be displayed on the List Box Button.
1. In the Design View window, select the List Box Button that you want to associate with a List Data
Table.
2. In the General tab of the Properties Control Window, click inside either the List Table Port or the
List Table Address fields. Clicking inside these fields enables the browse (...) button. Click this
button to access the Attach Table To List Box dialog.
3. This dialog lists all Static List Data Tables in your project. Select the table that you want to attach to
the selected List Box Button.
4. Enter the Table Port and Table Address of the dynamic List Table.
5. Click OK to save your changes and close the dialog.
Example NetLinx Code with List Data
The following is a NetLinx code example using Data List Commands to define a listing of music tracks
to display on the associated List Box Button.
