how to get a combination name using Eval()

Question

I'm wondering how to get a combination name like "test1" by using <%# Eval("id") %>

I want to name a div by the id field from a datatable, I can get the id in frontend by using <%# Eval("id") %>, I want the div name to be something like test1, test2.

Is this right?

<div id="<%# test+Eval("id") %>"></div>

This code is supposed to write in frontend page of an asp.net website project.

I thought that JavaScript was only available in classic ASP, not ASP.NET? — Quentin, Jan 25 '12 at 16:35

If the div is in a databound control use:

 <div id='<%# "test"+Eval("id") %>'></div>

Eval() method works only in a databound control

Single-Value Databinding
or if the id is a protected/public variable

 <div id="<%# "test"+id %>"></div>

or even call your own method (protected/public)

<div id= "<%# "test"+Counter() %>"></div>

Then in the page load event call this method

 DataBind()
