TreeListNode.HasAsParent详解
TreeListNode.HasAsParent详解TreeListNode元数据：
C# Code:
//
// 摘要:
// Determines whether the current node has a DevExpress.XtraTreeList.Nodes.TreeListNode
// instance as a parent.
//
// 参数:
// node:
// The DevExpress.XtraTreeList.Nodes.TreeListNode instance to check.
//
// 返回结果:
// true if the current node has a DevExpress.XtraTreeList.Nodes.TreeListNode
// instance as a parent; otherwise, false.
public bool HasAsParent(TreeListNode node)
{
}

TreeListNode.HasAsParent(TreeListNode node)
解释：检查参数中的节点是否当前节点的父节点。若node参数是当前节点的父节点，则HasAsParent方法返回True。
使用方法：
C# Code:
//检查修改后的结点是当前结点的子结点
if (nodeNew.HasAsParent(nodeOld))
{
this.SetEditorBindingValue(txtParentGroupCode, codeOld);//还原数据
e.Cancel = true;
Msg.Warning("乱套了！不能修改为它的子结点！");
}
