I need to display a running total in a datagrid. Each row should contain a column which includes the total from the previous row +/- a value from the current row.
The grid is bound to a collectionviewsource defined in Xaml.
The items in the source come from Linq Entities.
I know one way would be to create the source as a list of custom items and hold a total column that i can calculate before binding to the grid, but I was hoping there was a better way.
Can this be done with any sort of converter? There must be a better way.
