TreeView 树节点的处理 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using WinForm_CRUD.B
TreeView设置节点图标 没子节点的设置其图标为 0 有节点的设置其图标为 1 procedure TForm1.Button1Click(Sender: TObject);var i:Integer;begin with TreeView1 do begin for i:= 0 to Items.Count -1 do begin if Items[i].HasChildren then begin
功能:获取当前选中节点的子节点id集合. 步骤:1.获取当前节点 2.用ztree的方法transformToArray()获取当前选中节点(含选中节点)的子节点对象集合. 3.遍历集合,取出需要的值. treeNode:当前选中节点对象 function getChildNodes(treeNode) { var childNodes = ztree.transformToArray(treeNode); var nodes = new Array(); for(i = 0; i < chil
