Setting local variable through repeater and anchor or label

I have a repeater which fetches data from a database and shows some labels (or anchors). I have a local variable on this class which must be updated by the value retrieved from database. To cut the matter short, there is a list of labels shown by repeater, when user clicks one of them, a variable on the form (which is called swfFilename) is fetched and is passed to the flash object on the page. My code is shown below:

<ItemTemplate>
     <开发者_StackOverflow;a onclick="<%#swfFileName = DataBinder.Eval(Container.DataItem, "MediaFile").ToString() %>" href="Index.aspx"> <%#DataBinder.Eval(Container.DataItem, "Text") %></a>
</ItemTemplate>

My code is not working properly and it seems that it is not assigning new value to the variable. Any help to assign the fetched value to the swfFilename? BTW, Index.aspx is the same page that we are currently over.

Would creating a javascript function ousdide of the repeater that takes the mediaFile string as a parameter and then manipulates the swf object work?

So something along these lines ...

<script>
    function manipulateFlash(mediaFile) {
        // set do stuff to flash object
        // assign mediaFile to flash object etc.
    }
</script>

<asp:Repeater>
    ...
    <ItemTemplate>
        <a onclick="manipulateFlash('<%#DataBinder.Eval(Container.DataItem, "MediaFile").ToString() %>')" href="Index.aspx"> <%#DataBinder.Eval(Container.DataItem, "Text") %></a>
    </ItemTemplate>
    ...
</asp:Repeater>
