 ## Initialize form data with static SSR
 
 When a component adopts static SSR, the [`OnInitialized{Async}` lifecycle method](xref:blazor/components/lifecycle#component-initialization-oninitializedasync) and the [`OnParametersSet{Async}` lifecycle method](xref:blazor/components/lifecycle#after-parameters-are-set-onparameterssetasync) fire when the component is initially rendered and on every form POST to the server. To initialize form model values, confirm if the model already has data before assigning new model values in `OnParametersSet{Async}`, as the following example demonstrates.
