嘿，伙计们，我遇到了一个艰难的人。我有一个包含复选框列表的 radgrid。现在，当用户更改复选框时，复选框会进行回发并更改行的文本和颜色。现在，当它执行此操作时，会将焦点拉到该行。因此，如果我选中该框并向上滚动到页面顶部，它会将我拉回底部。我想做它，所以它不会改变任何焦点，只是做一个异步回发。

这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" />

现在这是整个网格，里面有复选框代码。同样，我只想停止焦点变化。我希望用户能够取消选中一个框并滚动，而不必担心他们的焦点会拉回他们更改的行。

我在这里找到了答案

<script type="text/javascript">

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

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