I have a "Total" column which uses a formula to summarize 7 other columns in my webgrid. The 7 input columns update just fine but the "Total" column won't update properly when I have the grid AJAX enabled;  only when I disable AJAX will the page truly postback and update the entire grid.

Can anyone recommend a way to keep AJAX enabled and have a formula column update properly using 2-way binding? Thank you in advance.
