NET-Connetor Exclude Filed for Update/Insert

i try to update a Table, with an calculated field. There must be a option to exclude that field.
Any Hints?

I’ll try it with
connector.BeforeUpdate += new EventHandler(connector_BeforeProcessing);

e.DataAction.Data.Remove … but i cant find the correct syntax

try the followingvoid connector_BeforeUpdate(object sender, DataActionProcessingEventArgs e) { e.DataAction.Data.Remove((TableField)"column_name"); }
