Inside repeater's itemtemplate I have a Panel server control.
I need to assign special Id for it, because I need to work with some javascript functions that use this Id.

In repeater ItemDataBound event I have this:

pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID");

But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback)

I tried to set the ID on aspx page like that:

<asp:Panel id='<%# Eval("ID") %>'

and some other variations but always get compile errors.
