FocusOnNavigate.cs

After navigating from one page to another, sets focus to an element matching a CSS selector. This can be used to build an accessible navigation system compatible with screen readers.

Properties

Assets	Gets the ResourceAssetCollection for the application. (Inherited from ComponentBase)
AssignedRenderMode	Gets the IComponentRenderMode assigned to this component. (Inherited from ComponentBase)
RendererInfo	Gets the RendererInfo the component is running on. (Inherited from ComponentBase)
RouteData	Gets or sets the route data. This can be obtained from an enclosing Router component.
Selector	Gets or sets a CSS selector describing the element to be focused after navigation between pages.

Methods

BuildRenderTree(RenderTreeBuilder)	Renders the component to the supplied RenderTreeBuilder.
DispatchExceptionAsync(Exception)	Treats the supplied exception as being thrown by this component. This will cause the enclosing ErrorBoundary to transition into a failed state. If there is no enclosing ErrorBoundary, it will be regarded as an exception from the enclosing renderer. This is useful if an exception occurs outside the component lifecycle methods, but you wish to treat it the same as an exception from a component lifecycle method. (Inherited from ComponentBase)
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 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. (Inherited from ComponentBase)
OnAfterRenderAsync(Boolean)	Method invoked after each time the component has been 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. 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. (Inherited from ComponentBase)
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.
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)
