Unbound Columns
The GridControl can display not only data from the specified data source, but also unbound columns with values calculated according to a formula based on other column values. Note that unbound columns are treated by the grid in the same way as regular columns, so they can be used to sort, group, filter and summarize data.
In this demo, the grid contains an unbound ‘Total with Discount’ column. Its values are calculated according to the “[Total]* (1-[Discount])” expression.
