Hi.
I am using the GridGroupingControl with treeview template and exceleditlike. I want to change one cell value based on another cell in the same row when it's editting completed.
For example, i have 3 column: Quantity, UnitPrice and TotalAmount
I want to update TotalAmount cell value = Quantity * UnitPrice when enter value for Quantity and UnitPrice.
How does one do this? Thanks!
