Class EventUtil

Namespace

MudBlazor

Assembly

MudBlazor.dll

Utility class for opting out of rerendering in Blazor when an EventCallback is invoked. By default, components inherit from ComponentBase, which automatically invokes StateHasChanged after the component's event handlers are invoked. In some cases, it might be unnecessary or undesirable to trigger a rerender after an event handler is invoked. For example, an event handler might not modify the component state. https://learn.microsoft.com/en-us/aspnet/core/blazor/performance?view=aspnetcore-6.0#avoid-rerendering-after-handling-events-without-state-changes
