将GridView里面选中的主键作为参数传递另外一个页面的办法？
将GridView里面选中的主键作为参数传递另外一个页面的办法？
这个用post怎么实现？

A页面代码：
  <script language="javascript" type="text/javascript">
  function SelectAll() {
  var cbList = document.getElementsByTagName("input");
  for (var i = 0; i < cbList.length; i++) {
  if (cbList[i].type == "checkbox") {
  cbList[i].checked = true;
  }
  }
  }

  function Post() {
  document.forms[0].submit();
  }
  </script>

  <form id="form1" runat="server" method="post" action="B.aspx">
  <div>
  <input id="BTN_POST" type="button" value="button" onclick="Post();" />
  <br />
  <input id="CB_SELECT_ALL" type="checkbox" onclick="SelectAll();" />全选<br />
  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
  DataKeyNames="DIC_ID">
  <Columns>
  <asp:TemplateField HeaderText="操作">
  <ItemTemplate>
  <asp:CheckBox ID="CB_SELECT" runat="server" />
  </ItemTemplate>
  </asp:TemplateField>
  <asp:BoundField DataField="DIC_ID" HeaderText="DIC_ID" SortExpression="DIC_ID" />
  <asp:BoundField DataField="DIC_CODE" HeaderText="DIC_CODE" SortExpression="DIC_CODE" />
  <asp:BoundField DataField="DIC_NAME" HeaderText="DIC_NAME" SortExpression="DIC_NAME" />
  <asp:BoundField DataField="PARENT_CODE" HeaderText="PARENT_CODE" SortExpression="PARENT_CODE" />
  </Columns>
  </asp:GridView>
  <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:JYJYConnectionString %>"
  SelectCommand="SELECT [DIC_ID], [DIC_CODE], [DIC_NAME], [PARENT_CODE],FROM [DICTIONARY_INFO] ORDER BY [DIC_ID]">
  </asp:SqlDataSource>
  </div>
  </form>
B页面接收：
  protected void Page_Load(object sender, EventArgs e)
  {
  StringBuilder sb = new StringBuilder();
  if(!IsPostBack)
  {
  if (Request["DIC_ID"] != null)
  {
  sb.Append(Request["DIC_ID"]);
  }
  Response.Write(sb.ToString());
  }
  }
但是B页面接收不到值
请问一下哪里有误？
请高手指点

------解决方案--------------------
Request["DIC_ID"] 名字不对,
------解决方案--------------------
沒看到在A頁面有傳入參數到B
------解决方案--------------------
A页面后台事件呢

HTML code

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="newsID,Us_ID"
        DataSourceID=&quo
