可以通过处理dropdownlist选择更改事件来完成.首先，将dropdownlist的autopostback属性从false更改为true.然后
< asp:dropdownlist id ="ddl1" runat ="server" autopostback ="true" onselectionindexchaged ="ddl1_onselectonindexchnaged">



在
后面的代码中
受保护的void ddl1_onselectionindexchanged(onject发件人，eventargs e)
{
sqldatadapter da =新sqldataadapter(从t_name选择*，其中co_name =" + ddl1.selectedvalue，cn);
....


}

ya you can do by handling dropdownlist selection changed event.First you change autopostback property of dropdownlist false to true.and
<asp:dropdownlist id="ddl1" runat="server" autopostback="true" onselectionindexchaged="ddl1_onselectonindexchnaged" >



in code behind

protected void ddl1_onselectionindexchanged(onject sender,eventargs e)
{
sqldatadapter da=new sqldataadapter("select * from t_name where co_name="+ddl1.selectedvalue,cn);
....


}

打开自动自动回传并绑定dropdownlist的gridview OnSelectedIndexChanged事件

Put auto autopostback on and bind gridview OnSelectedIndexChanged event of dropdownlist
