With Quick View forms, you can simply add the related entity fields to a form and then embed that Quick View form on the other related entity. In the example below, you will see how to setup a Quick View form as well as embed it on the related record.
Step 1: Create the Quick View form
For this step, go to the related entity of the primary form you need to display the data on. In this case we are using Contact and creating a Quick View form that contains the Contact’s email address and primary phone number.
New quick view form:
Add phone number and email address to the form then Save and Close:
Step 2: Add the Quick View form to the related entity form
In this step you will place your newly created Quick View form on the related entity to display the related information. In this case we will show the Primary Contact information on the Account form.
Open the Account form and locate the Quick View Form icon within the Insert Tab
Locate the area on the Account form that you would like the information from the Quick View form to be displayed (Preferably right below the Primary Contact lookup field) then click on the Quick View Form Button. Provide a Name and Label and select the lookup field to the related entity (Primary Contact), the related entity (Contact) and the Quick View Form to display (Contact Email and Phone)
Once you have selected everything click OK and move your Quick View form to the desired location and save your form. Then publish all customizations and confirm that the newly created Quick View form has been embedded on the Account form.
Take note that information on the Quick View form is Read Only. You will also notice that your instance of CRM 2013 probably has some Quick View forms already created by Microsoft.
Hopefully this helps make the most out of the Quick View form creation feature within CRM 2013.
