gridview中实现radiobutton的单选

c# 代码[csharp]
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                RadioButton rb = (RadioButton)e.Row.FindControl("rbtSelect");
                if (rb != null)
                    rb.Attributes.Add("onclick", "onClientClick('" + rb.ClientID + "','" + e.Row.RowIndex + "')"); //把选中行的RowIndex也传过去，提交后在服务器端取值时用
            }
        }

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                RadioButton rb = (RadioButton)e.Row.FindControl("rbtSelect");
                if (rb != null)
                    rb.Attributes.Add("onclick", "onClientClick('" + rb.ClientID + "','" + e.Row.RowIndex + "')"); //把选中行的RowIndex也传过去，提交后在服务器端取值时用
            }
        }
javascript代码
[javascript]
<script type="text/javascript">
       function onClientClick(selectedId, rowIndex)
       {
            //用隐藏控件记录下选中的行号
            var hidden = document.getElementById("Hidden1").value=rowIndex;

            var inputs = document.getElementById("<%=GridView1.ClientID%>").getElementsByTagName("input");
            for(var i=0; i <inputs.length; i++)
            {
                if(inputs[i].type=="radio")
                {
                    if(inputs[i].id==selectedId)
                        inputs[i].checked = true;
                    else
                        inputs[i].checked = false;

                }
            }
       }
     </script>

hmtl代码：
[html]
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
                    Width="648px" Font-Size="9pt" onrowcommand="GridView1_RowCommand"
                    DataKeyNames="id" onrowdatabound="GridView1_RowDataBound">
                    <Columns>
                    <asp:TemplateField>
                    <ItemTemplate>
                &nbs
