求教！如何获取GridView中ItemTemplate中的控件值？

Question

页面代码如下：<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    AllowPaging="True" PageSize="1" DataSourceID="SqlDataSource1" onpageindexchanged="GridView1_PageIndexChanged">
        <Columns>
             <asp:TemplateField>
                  <ItemTemplate>
                       <table style="width: 100%; height: 358px">
                           <tr>
                              <td colspan="2">
                                 <asp:Label ID="Label11" runat="server" Text="作答："></asp:Label>
                                 <asp:RadioButton ID="RadioButton1" runat="server" ForeColor="Red" 
                                            GroupName="as" Text="A" />
                                 <asp:RadioButton ID="RadioButton2" runat="server" ForeColor="Red" 
                                            GroupName="as" Text="B" />
                                 <asp:RadioButton ID="RadioButton3" runat="server" ForeColor="Red" 
                                            GroupName="as" Text="C" />
                                 <asp:RadioButton ID="RadioButton4" runat="server" ForeColor="Red" 
                                            GroupName="as" Text="D" />
                              </td>
                            </tr>
                       </table>
                   </ItemTemplate>
            </asp:TemplateField>
         </Columns>
</asp:GridView>  我想获取GridView中ItemTemplate中table中用户选了哪个RadioButton。我在cs文件中如何获取?

Answer 1

RadioButton RB= e.Row.findControl("RadioButton") as RadioButton;

Answer 2

看我的代码：onpageindexchanged="GridView1_PageIndexChanged" 这个事件。当页码变化以后才获取这个值。
这个事件的EventArgs参数根本没有Row这个属性。

Answer 3

楼主，你不要用GridView的PageIndexChanged事件，你换成PageIndexChanging事件，然后再用一楼的代码两个事件参数的不同：
1、PageIndexChanged
        protected void GridView1_PageIndexChanged(object sender, EventArgs e)
        {        }
2、PageIndexChanging
        protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {        }

Answer 4

你想在那个事件获取呢？
gridview外面就foreach (GridViewRow gr in GridView1.Rows)
        {            RadioButton chk = (RadioButton)gr.Cells[列数].FindControl("RadioButton1");
            if (chk.Checked)
            {                          }
        }

Answer 5

PageIndexChanging 索引改变时触发
PageIndexChanged 改变之后才触发

Answer 6

foreach (GridViewRow gvr in GridView1.Rows)
  {
    RadioButton rb= ((RadioButtonList)gvr.FindControl("RadioButton1"));}
