Using a Quick View Form on a record in Dynamics CRM is a good way to view information about a related record. Fields can be added to the Quick View Form and sub grid to associated records. There are times when a sub grid contains many records and to search the records you can enable the Search functionality by selecting the “Display Search Box” option when setting up the properties.
But once you view this sub grid on the form with the “Display Search Box” option enabled, the Search Box is mostly hidden. Entering text into the Search Box is possible but the text is not visible.
