I am trying to change the id of certain div/divs inside of repeater is there any psefic way to do it and can you be please explain basicaly.
<ItemTemplate>
<li id="11">
<img src="../<%#Eval("MediumPath")%>"class="items"alt='<%#Eval("Alt") %>'>
<br clear="all" />
<div><%# Eval("ProductName")%></div>
</li>
</ItemTemplate>
You can use container.ItemIndex, which gets the item index from the repeater. Just a note that it's 0 indexed so the actual code will be:
<li id="<%# Container.ItemIndex + 1 %>">
