Why don't you just use two different events for the save and the cancel buttons on the main form?

Don't use delegates - use events: you have three forms:
main -> second ->third
When you press the button in the third form, it signals an event which is handled in the second form.
This event handler raises an event which is handled by the main form which then refreshes it's own grid.

This is very simple to arrange: A Simple Code Snippet to Add an Event[^] shows you how (as well as adding a snippet to Visual Studio to make it easier later)
And Transferring information between two forms, Part 2: Child to Parent[^] shows an example of using events to do something similar.

Yeah, you can use delegates.
In my opinion events are delegates too. See my code below, it is not relevant to your answer, but you will certainly have an idea how it works

C#

Form_Load(...)
{
    addBtn.Click += delegate
    {
        // do your operations
    };
}

Let me know, if anything is not clear to you :)
