Hi,

I use a repeater that displays images.
I need to add dynamically a jscript function on each image that use the
index value of the repeater

<asp:Repeater ID="ph" runat="server" DataSourceID="myDataSource">
<ItemTemplate>
<asp:HyperLink runat="server" ID="link"
NavigateUrl="javascript:Slides(INDEXREPEATER)">
<asp:Image runat="server" ID="img" ImageUrl='<%#
Eval("myPic") %>' />
</ItemTemplate>
</asp:Repeater>

How to replace the INDEXREPEATER by the current index ?

Thanks in advance

Stan

Great.. it works..
I thank you
but now, I have a little problem :(
When I use
<asp:HyperLink id="link" runat="server"
NavigateUrl='javascript:Slides(<%=Container.ItemIndex%>);' >bla
bla</asp:Hyperlink> it doesn't eval the Container.ItemIndex

So when I look at my source, I get
<a href="javascript:Slides(<%=Container.ItemIndex%>);">bla bla</a>


Any idea ??

Try:

<asp:HyperLink id="link" runat="server"
NavigateUrl='<%# "javascript:Slides(" + Container.ItemIndex + ");" %>' >bla
bla</asp:Hyperlink>
