objectComponentBaseThemeBuilder
Methods
BuildRenderTree(RenderTreeBuilder)
Renders the component to the supplied Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.
protected override void BuildRenderTree(RenderTreeBuilder __builder)
Parameters
__builder
RenderTreeBuilder
OnAfterRenderAsync(bool)
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 Microsoft.AspNetCore.Components.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 System.Threading.Tasks.Task, because that would cause an infinite render loop.
protected override Task OnAfterRenderAsync(bool firstRender)
Parameters
firstRender
boolSet to
true
if this is the first time Microsoft.AspNetCore.Components.ComponentBase.OnAfterRender(bool) has been invoked on this component instance; otherwisefalse
.
Returns
- Task
A System.Threading.Tasks.Task representing any asynchronous operation.
Remarks
The Microsoft.AspNetCore.Components.ComponentBase.OnAfterRender(bool) and Microsoft.AspNetCore.Components.ComponentBase.OnAfterRenderAsync(bool) 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.
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.
