动态更改字幕文本，而无需更改字幕位置

Question

I am currently working on stock based web application and i want to display price of different stocks in marquee. Due to frequent change of stock prices i had to update text of marquee dynamically. Its easy to change text, but after updation marquee starts from initial position and thats the problem. Is there any way to change text without changing its current position???

I'm currently using update panel and timer to change its text.

    <ContentTemplate>
        <asp:Timer ID="Timer1" runat="server" Interval="1000" Enabled="True" OnTick="Timer1_Tick">
        </asp:Timer> 
        <marquee id="marque" style="width: 700px" direction="right" runat="server"></marquee>
    </ContentTemplate>

and changing text using back end .cs file marque.InnerText = dynamic_data;

The problem is, that you change the text in the code-behind file. That means a post-back is needed to change the text. A post-back is nothing else than a full reload of the page and for sure it resets your marquee.

Change the text on client side per javascript. If you need to bring the text out of the back-end, use a page method and connect from client-side to it.
