Hi Sudarsanam,
Not exactly sure what you're trying to achieve. If I understand correctly, you want to display another attribute from that entity everywhere. Let's say: you have used “Name” and now you want to use “DisplayName”.
I'm afraid the answer will be: no, there is not an user friendly way to change the used path on data grids easily.
There is a way, but it can have disastrous side effects, as it replaces all usages of that attribute and it destroys existing data, so you can only apply if there is no data in your app. So you can try, but use with caution:
