C# 过滤一个datagridview并保持与另一个datagridview的关系

我有两个

数据集

和两个

数据表

。绑定并显示在两个

数据网格上

：

//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;

如何筛选公司

datagrid

，而不失去与计划

datagrid

的关系

我试过这个，但似乎失去了联系：

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

---

好吧，这很简单，令人尴尬：

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