如何得到模版列里面的数据

就我使用到的情况先总结一下：
1、把模版列绑定的字段放在gridview的DataKeyNames里面，如DataKeyNames="id,is_used"
然后在后台的代码里面这样处理：
在行绑定的时候
   protected void sgvList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
            if (e.Row.RowType == DataControlRowType.DataRow)
        {
           string strIsued = this.sgvList.DataKeys[e.Row.RowIndex][2].ToString());
         }
   }
2、在后台写个方法绑定到前台的html代码中
 protected string ChangeIDtoName(object data)
    {
        string strIsUse = data.ToString();
        string strUse="";
        if (strID == "True")
        {
            strUse="使用";
        }
        else if (strID == "False")
        {
           strUse= "不使用";
        }
        return strName;
    }
前台代码：
  <%#ChangeIDtoName(DataBinder.Eval(Container, "DataItem.is_used"))%>
3、使用控件
 <asp:HyperLink ID="hlkCustomer" runat="server" NavigateUrl='<%#"~/Customer/EditCustomer.aspx?id="+Eval("Customer") %>' Text='<%# Eval("Customer") %>'></asp:HyperLink>
  protected void sgvList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {       
             HyperLink hlkCustomer = (HyperLink)e.Row.FindControl("hlkCustomer");
            objEntity = getEntity(this.sgvList.DataKeys[e.Row.RowIndex][3].ToString());//一个获取名字的方法
            if (objEntity != null)
            {
                hlkCustomer.Text = objEntity.Name;
          }
            else
            {
                hlkCustomer.Text = "";
            }
