TreeView怎么实现这个效果~
[解决办法]
this.treeView1.Nodes.AddRange(new TreeNode[] {
new TreeNode("T1201",new TreeNode[]{
new TreeNode("111"),
new TreeNode("222"),
new TreeNode("333")
}),
new TreeNode("T1202",new TreeNode[]{
new TreeNode("444"),
new TreeNode("555"),
new TreeNode("666")
}),
new TreeNode("T1203",new TreeNode[]{
new TreeNode("777"),
new TreeNode("888"),
new TreeNode("999")
})
});
this.treeView1.ExpandAll();
