Other Runtime - SetActive(false) or enabled = false will lose event binding

I discovered that if you make a game object containing a UIDocument inactive or you disable the UIDocument. Then any event bindings will be lost.

If you need to hide the document, use root visibility instead.

For example:

Code (CSharp):

1. public class MyClass : Monobehaviour
2. {
3.     [SerializeField]
4.     private UIDocument document; // set in inspector
5.  
6.     private void Start()
7.     {
8.         var myButton = document.rootVisualElement.Q<Button>("nameOfMyButton");
9.         myButton.clicked += () => Debug.Log("Button is clicked");
10.  
11.         document.enabled = false; // Don't do this! Event binding lost!
12.         gameObject.SetActive(false); // Don't do this! Event binding lost!
13.  
14.         document.rootVisualElement.visible = false; // DO THIS!
15.     }
16. }

In my case it was the "escape" menu that I was trying to create and then hide.

I used the UI Toolkit Event Debugger to see that the events were being fired on the buttons but no methods were called.

Posting here because it drove me mad for 3 hours.

 

Oh man, thank you. I also got this problem. You are genius
