我有个问题 . 我正在使用 BrightIdeasSoftware.TreeListView 在我的窗体中创建树视图，我也参考了How to create a MultiColumn treeview like this in C# Winforms app但是我没有成功创建它 . 你能告诉我，我在创建树视图时犯了什么错误 . 完整的描述如下 .
-
我想添加动态可折叠面板，并在此处想要添加树 .
-
数据将根据可折叠面板 Headers id显示在面板中 .
-
我有一个父ID，可以有多个孩子 .
-
状态列将显示一个图像
下面是我用于创建树视图的代码

public string Name { get; private set; }

public string Column2 { get; private set; }

this.Name = name;
this.Column1 = col1;
this.Column2 = col2;

}
