Show or Hide the icons in a report column in APEX

Question

Hi All,
I have a requirement to show or Hide a Delete Icon in my report.
Condition is whenever the transfer is completed, then the user should not see the Delete Icon for that particular row of the report. I.E. for example if there are 5 rows in the report, and for 2 rows the value of the Transfer is NULL, then the Delete icon should be appear to the user. If the value for the column transfer is Not Null for remaining 3 rows, then the user should not be able to see the Delete Icon.
For this I did like below,
In the report, I edited the Del_Icon and Selected 'Value of the Item/Column in Expression1 is NULL' and entered 'Transferred' in Expression1 in Conditional Display area. But even if the value for Transfer column is 'Transferred', the Delete Icon is still appearing for that row.
Can someone please let me know where can be the mistake is?
Please let me know if you require more info.
Actually in the application if we go to Transfer Page, there is an option to create a row for Transfer page. There is a column Transfer, If we do not enter any value for the column Transfer and submit the page, the record will be created and the Delete Icon should be appear. If I update the row in the application and provide some value, and click submit button, then the Delete Icon should not appear.

Answer 1

You can do one thing, check the condition in the report sql itself and display the image
select case
            when transfer is null then '<a onclick="f_func()"><img src="#APP_IMAGES#img"></a>'
            else null
            end col1,
         col2
from tableI have used "APP_IMAGES" you can changes it accordingly.
and the <a> tag should be like this *<a onclick="f_func()"*
in the javascript function you can submit the page using apex.submit('REQUEST') and condition your delete process on the REQUEST.
