Did you get any exception or error like Dynamic generation of Sql Command is not supported when query does not have key column information IS tableView a DataAdapter?

Solution 1

From the following statements of the question
tableView.Update(dset, "Info");
tableView.UpdateCommand = cb.GetUpdateCommand();

It can be seen that UpdateCommand is assigned after calling the Update method.
Just check whether there is any problem due to this.
