What if the component ref/instance is not working? Or the component ref is undefined?

Platform: Blazor| Category : Components, Troubleshooting

The component instance filed is populated along with the component after rendering completion. You must access the component instance in the OnAfterRenderAsync or OnAfterRender methods of the Blazor lifecycle.

@page "/"
 <Counter IncrementValue="10" @ref="counter"></Counter>
 @code {
     private Counter counter;    
     protected override void OnAfterRender()
         counter.increase(); //access counter instance here
