After an item is scanned or entered into collected data, remove that item from a list that has been filled from a Validation file.  The list will then display only the remaining items.

There are two methods:

1. Override script in the grid – The Override script may affect performance on the mobile device as the collected data records grow, as this script must search through each record.  This Override script is best used where collected data records are few, or where the communications license is a PC-based Runtime license; and can also be used with with a device-based device license.
   
2. SQL CE -  this option uses Microsoft’s SQL CE on the device to store both the validation file and the collected data, and to query the data.  This option may provide better performance where numerous records are collected.  The SQL CE is a free software download from Microsoft, and the 3 needed files must be installed to each device.  In addition, an ITScriptNet device license is required on the device (the PC-based Runtime license cannot be used when running SQL CE on a mobile device).
