in my asp.Net application, I have a parent gridview in which each cell of it has a child (nested) grid view, as shown in the attached photo.

in details, the parent gridview carries information while child carries actions, which they are implemented in LinkButton. once action is clicked, a process is done in backend and then the whole page is refreshed.

enter image description here

I need to enhance the Actions Button to show a "loading image" until the page is fully refreshed. I tried some JQuery codes but they look not working for nested linkbuttons.

appreciate your help.
