Asp.net 在autopostback上停止焦点更改=true

嘿，伙计们，我有一个艰难的一个。我有一个包含复选框列表的radgrid。现在，当用户更改复选框时，复选框将进行回发并更改行的文本和颜色。现在，当它这样做时，它会将焦点拉到那一行。因此，如果我选中该框并向上滚动到页面顶部，它会将我拉回到底部。我想让它不改变任何焦点，只做一个异步回发

这里只是从网格中拉出的复选框

 <asp:CheckBox runat="server" ID="isChecked" Checked='<%# Eval("active") %>' AutoPostBack="true"
                                          OnCheckedChanged="CheckChanged" ToolTip="Activate/In-activate relationship between Event and Category" />

下面是整个网格，其中包含复选框代码。再一次，我只想停止焦点的改变。我希望用户能够取消选中一个框并滚动，而不用担心他们的焦点被拉回到他们更改的行

我非常感谢你们在这个问题上提供的任何帮助

我找到了答案

var prm=Sys.WebForms.PageRequestManager.getInstance（）；
prm.add_beginRequest（函数（）{
prm.\u scrollPosition=null；
});

<script type="text/javascript">

var prm = Sys.WebForms.PageRequestManager.getInstance();

prm.add_beginRequest(function() {
    prm._scrollPosition = null;
});
