偶尔使用,简单的记录下过程
1.下载Newtonsoft.Json.Net20.dll后,放入Asp.net项目Bin文件夹中.
Newtonsoft.Json.Net20,是一个Object/Json转换工具,这里用来把对象转换成Json格式字符串.
2.树节点Model对象,
public class TreeModel{
private string _id,_parentid, _text;
private bool _leaf;
private List<TreeModel> _children = new List<TreeModel>();//子节点集合
public string id{
get { return _id; }
set { _id = value;}
}
public string parentid{
get { return _parentid; }
set { _parentid = value; }
}
public string text{
get { return _text; }
set { _text = value; }
}
public bool leaf{
get { return _leaf; }
set { _leaf = value; }
}
public List<TreeModel> children{
get { return _children; }
&nb
设置下拉框的初始值：
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Text="小学" Value="1"></asp:ListItem>
<asp:ListItem Text="中学" Value="2"></asp:ListItem& ......
