For those items, change their Read-Only condition to Value of Item/Column in Expression 1 is NOT NULL and set the Expression 1 field to your date column

>>this is working only for one column

Yes, because that is what you asked for in the original question. My answer was correct for what you stated initially: "where date column is there if the date column is not null"

Now you are asking about 4 columns and there's an additional requirement for a date match. In the future, please ensure to give the correct details or post a new thread with the new question.

What you probably want to do in this case is to change the Read-Only condition to PL/SQL Expression, then change the Expression 1 field to something like:
:P_COLUMN1 is not null
and :P_COLUMN2 is not null
and :P_COLUMN3 is not null
and :P_DATE_FIELD1 = :P_DATE_FIELD2  

Open in new window

The date condition his is where you need to be more specific as to what you actually have on your pages. You can add a separate validation to ensure that the date fields actually contain a correct date.
