[b]
注意两点：
[/b]1.要将gridview的AllowSorting属性置为true，同时设置OnSorting事件
2.在OnSorting事件中对排序的列设定SortExpression属性
[url=../UserLogin.aspx] }
ViewState["sortExpression"] = "Isdistribution";
ViewState["sort"] = " ASC";
}
//绑定信息
BindNodeInfo();

this.NodeGridView.DataSource = myview;
NodeGridView.DataKeyNames = new string[] { "node_id" }; //设置主键字段
NodeGridView.DataBind(); //绑定GridView控件
}
