过滤一个datagridview并保持与另一个的关系

Question

我有两个 datasets 和两个 datatables。绑定并显示在两个datagrids上：

//fill datatable
companiesDataTable = new DataTable("Companies");
scheduleDataTable = new DataTable("Schedule");
adapterCompanies.Fill(companiesDataTable);
adapterSchedule.Fill(scheduleDataTable);

//set dataset
myDataSet = new DataSet();
myDataSet.Tables.Add(companiesDataTable);
myDataSet.Tables.Add(scheduleDataTable);

//add relation
myDataSet.Relations.Add("FullSchedule",
                        myDataSet.Tables["Companies"].Columns["id"],
                        myDataSet.Tables["Schedule"].Columns["CompanyID"]);

//set binding sources
bsComp = new BindingSource(myDataSet, "Companies");
bsSched = new BindingSource(bsComp, "FullSchedule");

//fill datagrid
dataGridViewCompanies.DataSource = bsComp;
dataGridViewTimes.DataSource = bsSched;

我怎样才能过滤公司datagrid而不失去与日程安排datagrid的关系？

我试过这个，但关系似乎丢失了：

var view = myDataSet.Tables["Companies"].DefaultView;
view.RowFilter = filterString;                
dataGridViewCompanies.DataSource = view;

好吧，这太简单了：

            bsComp.Filter = filterString;
            dataGridViewCompanies.DataSource = bsComp;
