Refresh Parent Grid List Page When Child Is Edited In Spreadsheet Mode

Hello All,

I am looking to refresh just the grid of the parent table, not the page, when I make additions or changes to a field in spreadsheet mode on the child table. I have the parent table, "Test Plan Tests" with a child table, "Test Plan Steps". I have reviewed the documents, and I just can't get this to work if it is even possible. I have a "PassFail" field that gets updated on the parent table when the field "PassFail" on the child table gets updated.

The update from child to parent is working just fine, I just have to manually refresh the page to see the results on the parent table. I don't want to refresh the whole page, just the parent grid list page. I have included an image below.

I have code to change "PassFail" on the parent table, Test Plan Tests, when one of the radio buttons is selected on the child table, "Test Plan Steps". This works great. I just want to know if I can refresh the parent table grid without whole page refresh.

Thank you in advance.
