You will probably not find an Out-Of-The-Box approach for doing this. So I guess you are talking about blank properties with the WorkObject? From different classes? It might be difficult to present on a single grid.
Maybe you can call an activity to identify all properties for each WorkObject and present the result with a custom section.
My requirement is "I have a page list which is populating the date from back end. As some of the rows in a grid has null values. I just want to show the user a flag based on null values added from background while using SQL-Query to the data base.
Tried a different approach I,e. calling the when condition at the row level and the when condition is calling a decision table to return value and based on return value we setting a flag to the end user.
