Hi,

I'm using Mere Mortals .NET 3.6 (not sure if that matters here or not).

I've got an aspx page showing a header record and a gridview with child records displayed. I am using MM.Net's BOs but I think technically the gridview is bound to a dataset. When a value changes at the header level I need to recalculate some stuff in the child records and refresh the gridview. So I go through each datarow in the gridview's data set, recalculate one of the fields, then save the dataset to a session variable and do a GridView.DataBind().

This does NOT show the newly calculated values, in fact the gridview disappears from the form completely.

What am I doing wrong?
