實作
雙擊事件系結
treeList.MouseDoubleClick += treeList_MouseDoubleClick_InOne;
雙擊事件中
將sender作為treeList，再將treeList的資料源取出，是一個節點的List，
然后獲取當前選中的樹形節點的Id屬性
通過linq運算式獲取與Id想對應的節點，進而獲取節點物件，
示例代碼：
private static void treeList_MouseDoubleClick_InOne(object sender, System.Windows.Forms.MouseEventArgs e) { if (e.Button == System.Windows.Forms.MouseButtons.Left) { DevExpress.XtraTreeList.TreeList treeList = sender as DevExpress.XtraTreeList.TreeList; if (treeList != null && treeList.Selection.Count == 1) { object idValue = https://www.cnblogs.com/badaoliumangqizhi/p/null; string strIdValue =https://www.cnblogs.com/badaoliumangqizhi/p/ String.Empty; DataTreeNode nodeData = null; List<DataTreeNode> datasource = treeList.DataSource as List<DataTreeNode>; if (datasource != null) { idValue = treeList.Selection[0].GetValue("Id"); strIdValue = idValue.ToString(); nodeData = datasource.Where<DataTreeNode>(p => p.Id == strIdValue).FirstOrDefault<DataTreeNode>(); if (nodeData != null) { } } } } }
其中DataTreeNode參考上面博客，
