DataGrid and JavaScript

[Guest]

Can someone please tell me how I can get the following JavaScript to work
inside this datagrid!

What I'm trying to do is to have a layer that shows up with an image of an
employee when you onMouseOver an icon in the datagrid!

Some how I need each icon to have a different id that relates to an image
record in a database... At the moment I'm using Active Directory to pull the
users details from...

I would be really grateful if anyone could give me a hand with this or point
me in the right direction!

Thanks

<asp: Datagrid>
<Columns>
<asp:HyperLinkColumn HeaderText="" Text="<a href='#'
onMouseOver=MM_showHideLayers('Layer1','','show')
onMouseOut=MM_showHideLayers('Layer1','','hide')><img
src='../images/user.gif' border='0'></a>"></asp:HyperLinkColumn>
<asp:HyperLinkColumn HeaderText="Name" DataNavigateUrlField="Name"
DataNavigateUrlFormatString="{0}"
DataTextField="Name"></asp:HyperLinkColumn>
