How can I know that the user interface in unity is changed by the c# code?

I am instantiating many gameobjects in the unity by the c# code... And then make the scrollbar value 0 in order to scroll to the last object...but the scroll is landing me in the middle. Because of that there is a delay between unity and c# code. so the scrollbar changes before all the objects are shown.

How can I know that the user interface in unity is changed totally and I now can scroll to the end using a listener or something that tells me that you can now make the scroll and all objects are ready in the user interface??

MakeMessages();
Scrollbar.value = 0;

The scrollbar value is 0 before all messages are appearing in unity, so it is changing to 0.5 then.

You can detect Scrollbar value change with the Scrollbar.onValueChanged. Register the event in the OnEnable function and un-register it the OnDisable function.

public Scrollbar sb;

void OnEnable()
{
    //Register Scrollbar Event
    sb.onValueChanged.AddListener(scollBarChanged);
}

//Called when Scrollbar value changes
private void scollBarChanged(float value)
{
    Debug.Log("Input Changed");
}

void OnDisable()
{
    //Un-Register Scrollbar Event
    sb.onValueChanged.RemoveAllListeners();
}
