Soenneker.Blazor.Extensions.EventCallback

Small Blazor extensions that invoke an EventCallback only when its consumer assigned a delegate.

Installation

dotnet add package Soenneker.Blazor.Extensions.EventCallback

Usage

The extension removes repeated HasDelegate checks from reusable components:

@using Soenneker.Blazor.Extensions.EventCallback

<button @onclick="Save">Save</button>

@code {
    [Parameter]
    public EventCallback<Order> OnSaved { get; set; }

    private async Task Save()
    {
        Order order = await SaveOrder();
        await OnSaved.InvokeIfHasDelegate(order);
    }
}

The non-generic overload works the same way:

[Parameter]
public EventCallback OnClosed { get; set; }

await OnClosed.InvokeIfHasDelegate();

When no delegate is assigned, both overloads return Task.CompletedTask. When a delegate is assigned, invocation follows normal Blazor EventCallback.InvokeAsync behavior, including renderer dispatch and exception propagation. Await the returned task when subsequent work depends on the callback completing.
