In CRM we are often faced with the requirement of disabling the view picker of a lookup view.
Say we a have a lookup field called customerid on the form of another entity and on click of the lookup, we need to disable the view selector of the lookup view window.
In Crm 2011 this could be achieved with the following code
However in CRM 2013, you might find the code above not working as expected. To do the same in CRM 2013, the trick is not find the image of the particular lookup field and apply the code to the image tag.
Hope this helps!
