I don't think what you are doing is going to work I get an error when I try and set the DataSource as you are trying to do; however, in the code behind you do this:

Assuming you added a listener to your parent repeater's ItemDataBoundEvent, then you will need to change your linq query slightly to not use an anonymous type (Create a protected class that has your properties) In mjy case I am using dto as the class name.

void rep1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{

    Repeater rep2 = (Repeater)e.Item.FindControl("rep2");
    rep2.DataSource = ((dto)e.Item.DataItem).y;
    rep2.DataBind();
}

I'd love to learn why you think you can't solve this in the code behind.
