Create Hyperlink column inside attachment loop and add it in control collection like this:

SPWeb web = SPContext.Current.Web;
SPList list = web.Lists.TryGetList(DropDownListSelectCategory.SelectedItem.Value);
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
    SPListItemCollection oListItems = list.Items;
    foreach (SPListItem item in oListItems)
    {       
        SPAttachmentCollection collAttachments = item.Attachments;
        foreach (var attachment in collAttachments)
        {
            HyperLink hp = new HyperLink();
            hp.NavigateUrl = collAttachments.UrlPrefix + attachment;
            hp.Text = collAttachments.UrlPrefix + attachment;
            hp.ID = e.Item.ItemIndex.ToString(CultureInfo.InvariantCulture); 
            e.Item.Controls.Add(hp); 
        }
    }
}
