C# Winform 生成的两个DatagridViewTreeViewSelectColumn列该怎么进行数据联动?

R2DatagridViewTreeViewSelectColumn treAss = new R2DatagridViewTreeViewSelectColumn();

treAss.Width = 150;

treAss.HeaderText = css.FEILD_CHNAME;

treAss.Name = "col" + css.FILED_NAME;

treAss.DataPropertyName = css.FILED_NAME;

treAss.OnlySelectLeaf = true;

treAss.OnlySelectEnabled = true;

treAss.IsTextBoxEnabled = false;

treAss.FindParentMode = RFindParentNodeMode.ParentID;

treAss.NodeCodeMember = "Code";

treAss.NodeIDMember = "Id";

treAss.NodeNameMember = "Name";

treAss.NodeParentIDMember = "Parent_id";

treAss.FindParentMode = RFindParentNodeMode.ParentID;

switch (css.TABLE_ELEMENT)

{

case "GFM_ASS_ELE_CARD_PERSON":

List<Person> userDepartList = new List<Person>();

//if (css.FEILD_CHNAME == "使用人")

//{

userDepartList = AgencyManage.Instance.AllPerList.OrderBy(a => a.Code).ToList();

//}

if (css.FEILD_CHNAME == "使用人" && (Global.userRoleId.ToString().Equals("6603") || Global.userRoleId.ToString().Equals("6501")))

{

userDepartList = userDepartList.FindAll(a => a.DEPARTMENT_ID.Contains(comeDepId));

}

List<Person> personList = userDepartList.ToList();

treAss.DataList = personList;

break;

case "GFM_ASS_ELE_DEPARTMENT":

treAss.OnlySelectLeaf = false;

List<Department> dtList = AgencyManage.Instance.DepListByRole;

comeDepId = dtList[0].Id.ToString();

treAss.DataList = dtList.OrderBy(a => a.Code).ToList();

break;}

treAss.Tag = css;
