使用sql数据源在转发器的项模板中绑定下拉列表

We are having some performance issues with a page and I wanted to ask about this. If I have a repeater and in the itemtemplate of the repeater I have a dropdownlist bound to an sql datasource, will that selectcommand be called once per each item even though the same result is returned each time? If so, as a quick fix, would enable caching set to true and a cache duration specified ensure that that query is run only once per page life cycle? I know I should be using object datasource, but I want to try to fix this quickly for now. Thanks in advance.We are having some performance issues with a pa
