Maintaining Scroll Position on Post Back ASP.net not working

[stargazer]

Im using an Ajax update panel with a c# multiline textbox which updates on a timer, but it keeps scrolling to the top, Ive tried setting maintainginscrollpositiononpostback to true and also tried various javascripts. The broswer im using is IE.This is my asp code with a c# textbox on the form. \[code\] <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" Height="390px" TextMode="MultiLine" Width="836px"></asp:TextBox> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" /> </Triggers> </asp:UpdatePanel>\[/code\]Im quite new to the updatepanel so maybe something is wrong there,, Thanks\
