问题 My project contains a form which allows the entering of orders, using an UltraGrid . One column is a checkbox style column, to represent whether or not the order has been delivered. When the order reaches 'Stage 4 - Awaiting Goods Delivery', the user can set the column value to True , which in turn prompts a new window, to allow the user to enter the volume and value of the delivery.
