@ -158,7 +158,7 @@ Razor attribute binding is case-sensitive:
:::moniker range=">= aspnetcore-7.0"
To execute asynchronous logic after binding, use `@bind:after="{EVENT}"` with a DOM event for the `{EVENT}` placeholder. An assigned C# method isn't executed until the bound value is assigned synchronously.
To execute asynchronous logic after binding, use `@bind:after="{DELEGATE}"`, where the `{DELEGATE}` placeholder is a C# delegate (method). An assigned C# delegate isn't executed until the bound value is assigned synchronously.
Using an [event callback parameter (`EventCallback`/`EventCallback<T>`)](xref:blazor/components/event-handling#eventcallback) with `@bind:after` isn't supported. Instead, pass a method that returns an <xref:System.Action> or <xref:System.Threading.Tasks.Task> to `@bind:after`.
