Set Class Using Eval in Item Data Bound

Question

I have a Repeater item in which their is a tr elements like this. I want to set css class according to item index as alternating item.

My Design Code is Like This

    <ItemTemplate>
            <tr id='<%# Eval("RegNum").ToString()%>' class='<%# Eval("RowClass").ToString()%>'>

Item Data Bound like this but not working: ( Its Wrong )

        if (e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataBinder.Eval("RowClass", "bgBlack");
        }
        else
        {
            DataBinder.Eval("RowClass", "bgWhite");
        }

where bgWhite and bgBlack are css class.

Suggest Me how to achieve this.

you can see if the built-in ItemIndex property is divisible by two, and use that to set a css class:

class="<%# Container.ItemIndex % 2 == 0 ? "bgWhite" : "bgBlack" %>"

This has the benefit of being completely based in your UI code (ascx or aspx file), and doesn't rely on JavaScript.
