Ternary operation in asp.net in vb.net

Am trying to add an 'odd' class to a table row in a repeater control..

    <tr class="<%# If((Container.ItemIndex % 2 == 0), "even", "odd") %>">

I have verified that Container.ItemIndex returns the index number.

This causes it to throw this error.. First operand in a binary 'If' expression must be nullable or a reference type.

I also tried replacing the % with Mod keyword but it throws an "Expression expected" error..

Am new to coding asp.net in vb, tried searching for a solution but failed to get a working solution..

If your target audience have browsers that implement the right CSS3 features, you can also accomplish this task purely with CSS:

Try

<tr class="<%# If((Container.ItemIndex Mod 2 = 0), "even", "odd") %>">

To add to Amritpal answer, you should use Mod not %.

you should use only = instead of == and use mod
