问题描述

大家好，
我有一个数据列表.里面的数据列表我有表.内表我有tr
即默认情况下不显示的表格行.如何在下拉列表中找到该行，然后选择要更改的索引块和样式.

Hello All,
I have a data list. Inside data list i have table. Inside table i have tr
i.e.table row whose display is by default none. How to find that row at drop down select index change and style to be done block.

推荐答案

您需要迭代DataList 中的所有项目以找到并操纵它们.假设您要查找ID为ddlcountry的DropdownList，则可以使用下面的代码

You need to iterate all items in DataList to find the DropdownList and manipulate them. Say you want to find the DropdownList to which id is ddlcountry, then you can use the code below

foreach(DataListItem dlistItem in DataList1.Items)
{
   DropDownList ddlcountry=  dlistItem.item[i].
                findControl("ddlcountry") as DropDownList;
   if(ddlcountry!=null)
   {
     int id=Convert.ToInt32(ddlcountry.SelectedValue);
   }
}

希望这会有所帮助.

Hope this will help.
