I just came across scenario where we wanted to know contract details on Contract Line form and to my surprise you can not added contract look up on contract line form in CRM. Check it out you will be surprised too 🙂
Well after using IE Developer tool I found that there is hidden field which holds the contract GUID on this contract line form.
So you can use following line to get contract GUID on contract line form.
Hope this helps some one as well…
