急gridview添RadioButton

急！gridview加RadioButton

HTML code

<div>            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"             BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px"             CellPadding="3" CellSpacing="1" DataKeyNames="ID"             DataSourceID="AccessDataSource1" GridLines="None">            <Columns>                <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"                     ReadOnly="True" SortExpression="ID" />                <asp:BoundField DataField="pyear" HeaderText="计划年度" SortExpression="pyear" />                <asp:BoundField DataField="pnumber" HeaderText="计划编号"                     SortExpression="pnumber" />                <asp:BoundField DataField="ptype" HeaderText="计划类型" SortExpression="ptype" />                <asp:BoundField DataField="punit" HeaderText="申报单位" SortExpression="punit" />                <asp:BoundField DataField="pwman" HeaderText="填报人" SortExpression="pwman" />                <asp:BoundField DataField="pphone" HeaderText="联系电话" SortExpression="pphone" />                <asp:BoundField DataField="pwdate" HeaderText="填报日期" SortExpression="pwdate" />                <asp:BoundField DataField="pstate" HeaderText="审核状态" SortExpression="pstate" />                <asp:BoundField DataField="premark" HeaderText="备注" SortExpression="premark" />                <asp:TemplateField HeaderText="审核">                    <ItemTemplate>                        <asp:RadioButton ID="yesBtn" runat="server" Text="通过" GroupName="shenhe"                             AutoPostBack="True" />                        <asp:RadioButton ID="noBtn" runat="server"  Text="不通过" GroupName="shenhe"                             AutoPostBack="True" />                    </ItemTemplate>                </asp:TemplateField>            </Columns>            <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />            <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />            <RowStyle BackColor="#DEDFDE" ForeColor="Black" />            <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />            <SortedAscendingCellStyle BackColor="#F1F1F1" />            <SortedAscendingHeaderStyle BackColor="#594B9C" />            <SortedDescendingCellStyle BackColor="#CAC9C9" />            <SortedDescendingHeaderStyle BackColor="#33276A" />        </asp:GridView>        <asp:AccessDataSource ID="AccessDataSource1" runat="server"             DataFile="~/App_Data/fac.accdb" SelectCommand="SELECT * FROM [fpbasic]">        </asp:AccessDataSource>        </div>    <div>        <asp:Button ID="ButSubmit" runat="server" Text="提交" />    </div>

这样应该怎么写后台代码，当我点提交的时候使RadioButton的值存入到数据库中（因为有很多行，每一行的RadioButton都会有一个选项，是一次性提交，不是每选一次RadioButton就与服务器交互一次）

------解决方案--------------------

protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{ 
RadioButton yesBtn = row.FindControl("yesBtn") as RadioButton ;
RadioButton noBtn = row.FindControl("noBtn") as RadioButton;
if (yesBtn.Checked)
{
sql 语句update
}

if (noBtn.Checked)
{
sql 语句update
}
}
}
[解决办法]
你最好使用RadioButtonList啊，直接到得到，更新数据库

protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{ 
RadioButtonList x= row.FindControl("x") as RadioButtonList ;
sql = "update x set xx = " + x.SelectedValue;
}
}
[解决办法]
前面不是给你提示了吗？
另外
你需要注意
1， <asp:ListItem>通过</asp:ListItem>内容是否与数据库中一致
2，是否需要先绑定数据库中的原有设置
3，还需要注意2个都不选的情况
