控件id引用不到的问题

<asp:label ID="pageIndex" Runat="server" Font-Size="12px"></asp:label>页/共
<asp:label ID="pageCount" Runat="server" Font-Size="12px"></asp:label>页  
这是页面定义的控件
if(this.dataGrid1.PageCount<10)
{
this.pageCount.Text="1";
this.pageIndex.Text="1";
}
//this.Cpage1.Text=this.dataGrid1.CurrentPageIndex.ToString();
int count=0;
count=this.dataGrid1.PageCount-1;
this.pageIndex.Text=count.ToString();
this.pageIndex.Text=this.dataGrid1.CurrentPageIndex.ToString();
这样引用却说控件；E:\infosys_wz\JZTD\zbxx\Main.aspx.cs(71): “infosys.JZTD.zbxx.Main”并不包含对“pageIndex　和pageCount”的定义不知道怎么会事，是不是保存的编码问题？？？

注意page_load里面使用
Page.IsPostback()
错了，你的这两个控件外面有没有容器啊？比如说有没有PAN或者其他服务器控件？
这个时候要this.objcet(那个容器).pageIndex.....
我放在一个表里面的:
<table height="28" cellSpacing="0" cellPadding="0" width="100%">
<tr>
<td class="table_bottom" align="right"><asp:linkbutton id="Linkbutton1" onclick="PagerButtonClick" runat="server" CommandArgument="0">首  页</asp:linkbutton>  |  
<asp:linkbutton id="Linkbutton2" onclick="PagerButtonClick" runat="server" CommandArgument="prev">上一页</asp:linkbutton>  |  
<asp:linkbutton id="Linkbutton3" onclick="PagerButtonClick" runat="server" CommandArgument="next">下一页</asp:linkbutton>  |  
<asp:linkbutton id="Linkbutton4" onclick="PagerButtonClick" runat="server" CommandArgument="last">尾  页</asp:linkbutton>  |  
第<asp:label id="lblCurrentIndex" runat="server"></asp:label>页/总<asp:label id="lblPageCount" runat="server"></asp:label>页  
跳转
<asp:dropdownlist id="tz" runat="server" AutoPostBack="True"></asp:dropdownlist>  </FONT>      </td>
</tr>
</table>
我保存的时候提示：有写字符不会被保存，要保存请选择另存为字符为unicode字符，
还问个问题:
function selectAll(ckbox)
{
          var thebox = ckbox;
          xState = thebox.checked;
          elem = thebox.form.elements;
          for(var i=0;i<elem.length;i++)
          {
           if(elem[i].type=="checkbox" && elem[i].id!=thebox.id)
           {
            if(elem[i].checked!=xState)
              elem[i].click();
           }
          }
}
<input id="ckbox" type="checkbox" runat="server" onclick="selectAll(this)">
为什么这样调用无效？？？？

如果是在DataGrid中的，那就不能只用用，要用FindControl，如果没在DataGrid中，将两个Label删了，重新拖两个上去看看。

这是web的代码！
在CS代码中手动把这两个Label的声明加上去嘛
这2个控件是不是包含在类似于panel控件里
如是的话.this.panel1.Pageindex.text
