gridview中实现checkbox的单选处理

gridView中

<asp:TemplateField HeaderText="选择">
      <ItemTemplate>
              <asp:CheckBox ID="cbId" checked="false" runat="server" />
      </ItemTemplate>
</asp:TemplateField>

gridview的RowDataBound事件

    /// <summary>
    /// 列表数据行绑定事件处理程序 
     /// </summary>
    /// <param name="sender">事件对象</param>
    /// <param name="e">事件参数</param>
    protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //为每个checkbox绑定setRadio事件
        System.Web.UI.WebControls.CheckBox cbx = e.Row.FindControl("cbId") as System.Web.UI.WebControls.CheckBox;
        try
        {
            //绑定选中CheckBox客户端ID             
            cbx.Attributes.Add("onclick", "Change(" + cbx.ClientID + ")");
            GridViewRow item = e.Row;
            if (item.RowType.Equals(DataControlRowType.DataRow))
            {
                CustomerCardInfosInfo customerCardModel = (CustomerCardInfosInfo)item.DataItem;
                //卡状态
                item.Cells[4].Text = CommonOperation.GetStatus(customerCardModel.Status);
            }
        }
        catch
        {
        }
    }

前台js实现checkbox单选效果

<script type="text/javascript">
            function Change(SCHeckBox) {
                var objs = document.getElementsByTagName("input");
                for (var i = 0; i < objs.length; i++) {
                    if (objs[i].type.toLowerCase() == "checkbox")
                        objs[i].checked = false;
                }
                var SelectCheckBoxID = SCHeckBox.id;
                document.getElementById(SelectCheckBoxID).checked = true;
            }
</script>

后台获取gridview列表值

        foreach (GridViewRow gvr in gvList.Rows)
        {
            if (((CheckBox)gvr.FindControl("cbId")).Checked)
            {
                int index = gvr.RowIndex;

                asn = gvList.Rows[index].Cells[1].Text;
                driverName = gvList.Rows[index].Cells[2].Text;
                vehicleNo = gvList.Rows[index].Cells[3].Text;
            }
        }
