Set a variable

[JFB]

Hi all,
My problem is to go back to desing view because I have bad format with
quotes in my onlclick.
onclick="ShowContent('btnNotes_<%#container.dataItem("ID")%>'); return
true;"
I want to set a value of a variable for <%#container.dataItem("ID")%> so I
can pass the value to the dynamic form field name.
I try this but it doesn't work.

<%Dim dataID
dataID = #container.dataItem("id") %>

Any ideas?
Tks
JFB
