gridview.row.count 问题 在线等

Question

我想遍历radiobutton，先都设置为未选中，然后选中某一个，因为启用了分页，如果总数据3条的话，每页显示2条的情况下，我选中第一页的rb时gvSelectSection.Rows.Count为2，我选中第二页的rb时gvSelectSection.Rows.Count为1。不启用分页gvSelectSection.Rows.Count就是3没问题的。为什么一分页count就只是当前页数的count了，我想遍历所有页的rb时该怎么写？？  for (int i = 0; i < gvSelectSection.Rows.Count; i++)
            {
                RadioButton rb = (RadioButton)gvSelectSection.Rows[i].FindControl("rbSelectSection");
                rb.Checked = false;
            }
            for (int i = 0; i < gvSelectSection.Rows.Count; i++)
            {
                RadioButton rb = (RadioButton)gvSelectSection.Rows[i].FindControl("rbSelectSection");
                if (rb == (RadioButton)sender)
                {
                    rb.Checked = false;
                }
<asp:GridView ID="gvSelectSection" runat="server" AutoGenerateColumns="False" AllowPaging="true"

你看生成的html就知道为什么分面以后就不显示全部的rb了
