[UI] How to force Content Size Fitter Update after instantiating a prefab?
Hi everyone,
I have a quite complexe interface with scroll rect and everything. All is ok BUT, when i instantiate a prefab in a parent which contains a content size fitter component, the size is not update until i enable/disable the game object in the editor.
I've already tried some weird coroutines with WaitForEndOfFrame(), then re-enable object, and other functions like :
LayoutRebuilder.ForceRebuildLayoutImmediate(UIManager.Instance.GetComponent<RectTransform>());
Canvas.ForceUpdateCanvases();
LayoutRebuilder.MarkLayoutForRebuild(this.transform as RectTransform);
Nothing is working atm and i wonder why i can't force the UI to redraw. Any ideas?
I've had the same problem and found a tricky workaround - changing the spacing of the layout group (even by as little as 0.01) forces the content size fitter to update. Just add & subtract 0.01 alternately every time you instantiate your prefab.
there are only getters, no setters ( at least in unity 2019.1 )
