Optional base class for components that represent a layout. Alternatively, components may implement IComponent directly and declare their own parameter named Body.

Constructors
| LayoutComponentBase() |
Properties
| Assets |
Gets the ResourceAssetCollection for the application. (Inherited from ComponentBase) |
| AssignedRenderMode |
Gets the IComponentRenderMode assigned to this component. (Inherited from ComponentBase) |
| Body |
Gets the content to be rendered inside the layout. |
| RendererInfo |
Gets the RendererInfo the component is running on. (Inherited from ComponentBase) |
Methods
| BuildRenderTree(RenderTreeBuilder) |
Renders the component to the supplied RenderTreeBuilder. (Inherited from ComponentBase) |
| DispatchExceptionAsync(Exception) |
Treats the supplied 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. (Inherited from ComponentBase) |
| 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. (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. |
| 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) |
