2-Way Data Binding in UpdatePanel

This works perfectly... until I try to Insert a record. I get an error 'Can not insert value NULL into column because column does not allow nulls.'

I don't think you are getting a NULL error because of the update panel, but rather the value you insert into the textbox isn't getting used in the INSERT statement. Do you have any code-behind and what does your markup code look like?
