I have a grid with a Total column. Each time an entry the Total needs to be updated.

In the Bofore Row Column change. I have the code:
replace Total with A + B + C + D
This.Refresh

When I move to a new cell, no visual update occurs.
If I return to the same cell and move off of it a second time, the update does occur.

Does anyone know how to make the update occur the first time?
