I have a datagrid bound to a collectionviewsource. I am also binding a textbox to one of the fields in the datagrid to do editing to the data outside the datagridcontrol. This binding works fine, except I can’t edit any of the data using the textbox. When I type something in the textbox, it doesn’t populate back to the object or the datagrid and when I switch rows back and forth I lose the data changes. How do I get the changes to persist?
