1.1字段设置:
1.1字段设定
(1)Run Designer
(2)点击 Colums
(3)点击Add添加列,需设置Name(字段名),FiledName(绑定名),Caption(显示名)
1.2代码实现:
(1)初始化树
this.StructureTreeDataSource = BTProduct.Select(p=>p.FState==1 && p.KParentId==null).ToList();
foreach(TreeListNode NOde in StructreTreeNodes)
{
int sid = Convert.ToInt32(node.GetValue(StructreTree.Columns[2]));
node.HasChildren = BTProduct.Select (p=>p.KarentId==sid && p.Fstae ==1).cout()>0?true:false
}
(2)树展开事.触发BeforeExpand事件
private void StructureTree_BeforeExpand(object sender.DevExpress.XtraTreeList.BeforeExpandEventArgs e)
{
if(e.Node.NOdes.Cont==0)
{
int sid = Convert.ToInt32(e.Node.GetValue(StructureTree.Columns[2]));
List<Tproduct> list = BTproduct.Select(p=>p.KParentId==sid && p.Fstate==1).ToList();
foreach(Tproduct sr in list)
{
TreeListNode tl = StructureTree.AppenNode(null,e.Node)
tl.Setvalue(StructreTree.Columns[0],sr.FProductId&& p.Fstate==1)
.count()>0 ? true:false}
}
}
}
(3)获取树某个点的数据
ProductId = Convert.ToInt64(StructureTree.FousedNode.GetValue(ID))
