Methods
BuildRenderTree(RenderTreeBuilder)
Dummy method required to allow Blazor's compiler to generate C# from .razor files.
protected virtual void BuildRenderTree(RenderTreeBuilder builder)Parameters
builderRenderTreeBuilder
CreateTestRenderer()
Creates the renderer.
protected override ITestRenderer CreateTestRenderer()Returns
Render(RenderFragment)
Renders the renderFragment and returns it as a IRenderedFragment.
public virtual IRenderedFragment Render(RenderFragment renderFragment)Parameters
renderFragmentRenderFragmentThe render fragment to render.
Returns
RenderComponent<TComponent>(params ComponentParameter[])
Instantiates and performs a first render of a component of type TComponent.
public virtual IRenderedComponent<TComponent> RenderComponent<TComponent>(params ComponentParameter[] parameters) where TComponent : IComponentParameters
parametersComponentParameter[]Parameters to pass to the component when it is rendered.
Returns
- IRenderedComponent<TComponent>
The rendered
TComponent.
Type Parameters
TComponentType of the component to render.
RenderComponent<TComponent>(Action<ComponentParameterCollectionBuilder<TComponent>>?)
Instantiates and performs a first render of a component of type TComponent.
public virtual IRenderedComponent<TComponent> RenderComponent<TComponent>(Action<ComponentParameterCollectionBuilder<TComponent>>? parameterBuilder = null) where TComponent : IComponentParameters
parameterBuilderAction<ComponentParameterCollectionBuilder<TComponent>>The ComponentParameterBuilder action to add type safe parameters to pass to the component when it is rendered.
Returns
- IRenderedComponent<TComponent>
The rendered
TComponent.
Type Parameters
TComponentType of the component to render.
Render<TComponent>(RenderFragment)
Renders the renderFragment and returns the first TComponent in the resulting render tree.
public virtual IRenderedComponent<TComponent> Render<TComponent>(RenderFragment renderFragment) where TComponent : IComponentParameters
renderFragmentRenderFragmentThe render fragment to render.
Returns
- IRenderedComponent<TComponent>
Type Parameters
TComponentThe type of component to find in the render tree.
Remarks
Calling this method is equivalent to calling Render(renderFragment).FindComponent<TComponent>().
