Methods

BuildRenderTree(RenderTreeBuilder)	Renders the component to the supplied RenderTreeBuilder.
InvokeAsync(Action)	Executes the supplied work item on the associated renderer's synchronization context. (Inherited from ComponentBase)
InvokeAsync(Func<Task>)	Executes the supplied work item on the associated renderer's synchronization context. (Inherited from ComponentBase)
OnAfterRender(Boolean)	Method invoked after each time the component has been rendered. (Inherited from ComponentBase)
OnAfterRenderAsync(Boolean)	Method invoked after each time the component has been rendered. Note that the component does not automatically re-render after the completion of any returned Task, because that would cause an infinite render loop.
OnInitialized()	Method invoked when the component is ready to start, having received its initial parameters from its parent in the render tree.
OnInitializedAsync()	Method invoked when the component is ready to start, having received its initial parameters from its parent in the render tree. Override this method if you will perform an asynchronous operation and want the component to refresh when that operation is completed. (Inherited from ComponentBase)
OnParametersSet()	Method invoked when the component has received parameters from its parent in the render tree, and the incoming values have been assigned to properties. (Inherited from ComponentBase)
OnParametersSetAsync()	Method invoked when the component has received parameters from its parent in the render tree, and the incoming values have been assigned to properties. (Inherited from ComponentBase)
SetParametersAsync(ParameterView)	Sets parameters supplied by the component's parent in the render tree. (Inherited from ComponentBase)
ShouldRender()	Returns a flag to indicate whether the component should render. (Inherited from ComponentBase)
StateHasChanged()	Notifies the component that its state has changed. When applicable, this will cause the component to be re-rendered. (Inherited from ComponentBase)
