Ext.net GridPanel获取选中行的数据

1、前台页面

在button中添加ExtraParams

 

<DirectEvents>
    <Click>
           <ExtraParams>
                   <ext:Prameter Name="Values" Value="Ext.encode({#GridPanelName}.getRowsValues({selectedOnly:true}))" Mode="Raw">
            </ExtraParams>
    </Click>
</DirectEvents>

Tips：（1）Ext.encode()  将对象转换成Json字符串；Ext.decode() 将Json字符串转换成对象

2、后台代码

string json=e.ExtraParams["Values"];     //得到json格式的数据
Dictionary<string, string>[] detail = JSON.Deserialize<Dictionary<string, string>[]>(json);        //反序列化json成字典
foreach(Dictionary<string, string> row in sqlDetail  )
{
           string id=row["ID"];.....        获取数据
}

Tips：JSON序列化与反序列化

（1）字典 Dictionary

//序列化
Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add("Name", "张三");
dic.Add("Age", "");
dic.Add("Gender", "女");
string json = JSON.Serialize(dic);  

//反序列化
string json= @"[{"Name":"张三","Age":18,"Gender":"女"}]";
Dictionary<string, string> dic = JSON.Deserialize<Dictionary<string, string>>(json);

（2）集合 List

//序列化
List<Person> list = new List<Person>();
list.Add(new Person{Name="张三",Age=,Gerder="女"});
list.Add(new Person{Name="李四",Age=,Gender="男"});
string json = JSON.Serialize(list);

//反序列化
string json=@"[{"Name":"张三","Age":18,"Gender":"女"},{"Name":"李四","Age":21,"Gender":"男"}]";
List<Person> list= JSON.Deserialize<List<Person>>(json);
