Answer 1

DataItemBound事件里面编写代码不就可以了？

Answer 2

先到用findcontrol()把在gridview里面的radiobuttonlist找到，然后通过findValue与绑定的数据相比。其实绑定方法跟一般的用法一样，关键就是要用findcontrol()找到gridview里面的radiobuttonlist这控件。

Answer 3

这个如果是个显示列表的话
在sql中使用 case 不就可以了么case '字段' when (字段= 值1) then 结果
             when (字段=值2) then 结果
             else 结果
             end

Answer 4

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            RadioButtonList rd = (RadioButtonList)e.Row.FindControl("RadioButtonList1");
            HiddenField hf = (HiddenField)e.Row.FindControl("hfSex");            if (hf.Value == "1")
                rd.Items[0].Selected = true;
            else
                rd.Items[1].Selected = true;        } 

Answer 5

事实上，我在发贴之前就用过4楼的方法，
但是当我进入编辑状态，RadioButtonList1显示出来后，它并没有选中任何一个值，全部处于未选中状态

Answer 6

还有，SQL出来的bit类型要么是"True",要么是"False"

                        </ItemTemplate>
                        <ControlStyle Width="30px" />
                    </asp:TemplateField>
</asp:GridView>
不用设置RowDataBound事件。
