推荐答案
您可以使用
You can access the radio button using DataListItem.FindControl()[^]
You can do something like-
RadioButtonList rbtnlist=( RadioButtonList)DataList1.Items[0].FindControl("RadioButtonList1"));
这将使您从数据列表的第一项中获得单选按钮列表.您可以使用for或foreach循环遍历所有行以查找所有值.
希望对您有帮助:)
This will get you the radiobuttonlist from the first item of the datalist. You may iterate through all the rows using for or foreach loop to find all the values.
Hope, it helps :)
