Hi there, i'm new to VS.NET and learning about dataviews now. Let's say i set up a dataview called dvCustOrder with many columns. I then save it and apply it to my datagrid. It works fine. But when i decide to take away some columns, i switch to design view for the dvCustOrders and uncheck those columns i don't want and save it. Then i run the project and it gives me an error. Basically my changes to the dv isn't reflected on the datagrid. What should i do next time if i want to make changes to my dv?
