repeater question

[rouqiu]

Hello,
I want to set a unique id for each item in a repeater like this:

<asp:repeater id=__theTabStrip runat="server" DataSource='<%#
DataBinder.Eval(Container,"TabText") %>'>
<ItemTemplate>
<asp:Button Runat="server" id="<%# Container.DataItem %>" BackColor="<%#
SetTabBackColor(Container) %>" />
</ItemTemplate>
</asp:repeater>

However, the id="<%# Container.DataItem %>" generates an error:'<%#
Container.DataItem %>' is not a valid identifier.

Would someone please tell me what I did wrong?

Id's can't be determined at databound time, they must be determined earlier.
Besides, there's no reason why you'd want a unique id. You don't access a
control like this by id, but rather use a FindControl() of the individual
repeateritem.

Check out:

for an example.
