Force Immediate Layout Update

This works on my case (Unity 2021.3.10f1)

Code (CSharp):

1. IEnumerator RefreshUI()
2.     {
3.         yield return new WaitForEndOfFrame();
4.      
5.         _horizontalLayoutGroup.SetLayoutHorizontal();
6.         LayoutRebuilder.ForceRebuildLayoutImmediate((RectTransform)_horizontalLayoutGroup.transform);
7.     }

 

Chiming in, this is the only thing that worked for me (tried all the above solutions and others):

Code (CSharp):

1. private IEnumerator ForceUpdateLayout(Component panel)
2. {
3.     var layoutgroup = panel.GetComponentInChildren<LayoutGroup>();
4.     if (layoutgroup != null)
5.     {
6.         yield return null;
7.         layoutgroup.enabled = false;
8.         layoutgroup.enabled = true;
9.     }
10. }

It's baffling that this is still such an issue in a product that exists for years... (Unity 2021.3.11f1)

 

this is the only thing that worked for me

 

I encountered the same problem. I rebuilt the UI layout without using any Content Size Fitter components following Gresolio's suggestions and it now works perfectly. I highly recommend using Layout Elements to achieve the auto-sizing and responsive layout goal.

 

Real life saver here, finally got my layout groups doing what they're supposed to be doing. Don't get why this is still such a problem, given the amount of people having issues with it.
