DevExpress TreeListLookupEdit常用技巧

//设定为CheckBox可用            

this.treeListLookUpEdit1.Properties.TreeList.OptionsView.ShowCheckBoxes = true;

//设定默认显示值            

this.treeListLookUpEdit1.EditValue = "http://www.mamicode.com/请选择";

 

//获取CheckBox选中项的

List<TreeListNode> aa=treeListLookUpEdit1TreeList.GetAllCheckedNodes();

 

//数据绑定(3种方法,不推荐直接绑定List<T>类型)

方法1:DataTable

//设置父子递归关系字段            

this.treeListLookUpEdit1.Properties.TreeList.KeyFieldName = "DepartmentID";            

this.treeListLookUpEdit1.Properties.TreeList.ParentFieldName = "ParentID";

//设置绑定字段和显示字段            

this.treeListLookUpEdit1.Properties.ValueMember = "DepartmentID";            

this.treeListLookUpEdit1.Properties.DisplayMember = "DepartmentName";

//绑定数据源            

this.treeListLookUpEdit1.Properties.DataSource = dtSource;

★说明  如果不需要获取节点值的情况下可以绑定DataTable,List<T>,BindingList<T> 三种数据源

其中后两种可以通过构造函数进行简单转换。区别在于数据源绑定BindingList的时候可以方便的获取节点值(该问题TreeList,GridControl同样存在)

List<DepartmentInfo> lstDepartment=new List<DepartmentInfo>();

BindingList<DepartmentInfo> aa=new BindingList<DepartmentInfo>(lstDepartment);

 

获取节点值方法(对应上述绑定的泛型方法):

DepartmentInfo tt = this.treeListLookUpEdit1TreeList.GetDataRecordByNode(tln) as DepartmentInfo;  //数据源绑定BindingList<DepartmentInfo>

DataRowView drv = this.treeListLookUpEdit1TreeList.GetDataRecordByNode(tln) as DataRowView;  //数据源绑定DataTable
