Hi All,
I was trying to build a custom filter box based on the blog https://community.sagecrm.com/partner_community/b/hints_tips_and_tricks/archive/2009/10/29/building-list-screens-with-filterboxes.aspx . Everything works fine except --All-- Option is missing. I tried with 'AllowBlank = true', Only --None-- option is showing on the list --All-- is not showing.
Any idea how I can add the --All-- option?
