C# 在div内保持gridview的滚动位置

我有一个包含脚本管理器的母版页。在子页中，我有一个带有复选框和一些文本框的可滚动gridview

    <div id="grdScr" style ="width:130%;  overflow:auto" align="center" >
        <asp:GridView ID="dgvBill" runat="server" AutoGenerateColumns="False"

我的gridview位于更新面板内。文本框在其TextChange事件中的gridview中进行一些数学计算，而autopostback对它们来说是真的

---

每当我按tab键将光标移动到下一个文本框时，页面将被回发，并且滚动位置不会保持。我将如何解决这个问题？

如果您的

GridView

位于

UpdatePanel

中，为什么不显示它呢？在更新面板中有许多其他控件，如TextBox，dropdownlist等。所以我忽略了这一点。你到底想做什么？当我在gridview内的文本框中输入一些值并按tab键时，我必须再次滚动到上一次滚动的位置。我不想再次滚动
