Hi Vasudha,
There is another way you can do this, you can write a c# mothod that returns a bolean value whether to show/hide section and call this method in the conditional formatting of the field using xdExtension.
Note: In one of your previous posts I have given links which give info on xdExtension.
Sorry I will not be able to provide an example because it takes time build all of that.
But we do paid service if you want, you can talk to Patrick if you need any paid service.
