在autopostback上停止焦點更改= true

Question

嗨，我有一個艱難的人。我有一個包含複選框列表的radgrid。現在，當用戶更改複選框時，複選框執行回發並更改行的文本和顏色。現在，當它這樣做時，它把焦點放在那一行上。因此，如果我選中該框並滾動到頁面頂部，它會將我拉回到底部。我想這樣做，所以它不會改變任何焦點，只是做一個異步回發。

這裏只是從電網拉

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

複選框現在，這裏是整個網格里面的複選框代碼。我再次想停止焦點改變。我希望用戶能夠取消選中一個框並進行滾動，而不用擔心他們的焦點回到他們改變的行上。
