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
