Method invoked after each time the component has rendered interactively and the UI has finished updating (for example, after elements have been added to the browser DOM). Any ElementReference fields will be populated by the time this runs.

This method is not invoked during prerendering or server-side rendering, because those processes are not attached to any live browser DOM and are already complete before the DOM is updated.

protected:
 virtual void OnAfterRender(bool firstRender);
protected virtual void OnAfterRender (bool firstRender);
abstract member OnAfterRender : bool -> unit
override this.OnAfterRender : bool -> unit
Protected Overridable Sub OnAfterRender (firstRender As Boolean)

Parameters

firstRender
Boolean

Set to true if this is the first time OnAfterRender(Boolean) has been invoked on this component instance; otherwise false.

Remarks

The OnAfterRender(Boolean) and OnAfterRenderAsync(Boolean) lifecycle methods are useful for performing interop, or interacting with values received from @ref. Use the firstRender parameter to ensure that initialization work is only performed once.
