HxMessageBox #

Component to display message-boxes.
Usually used via HxMessageBoxService and HxMessageBoxHost.

HxMessageBox is a implementation component you use directly only in rare specific cases.
Usually you use the message box by using the IHxMessageBoxService injected service and its ShowAsync method (or derived extension methods).

Basic usage #

Inject the IHxMessageBoxService to your code and use one of it's methods to raise the message box:

Task<MessageBoxButtons> ShowAsync(MessageBoxRequest request) - original method
Task<MessageBoxButtons> ShowAsync(string title, string text, MessageBoxButtons buttons = MessageBoxButtons.Ok, MessageBoxButtons? primaryButton = null, string customButtonText = null) - extension method
Task<bool> ConfirmAsync(string title, string text) - extension method
...or you can add your own extension method

ShowAsync result: None
Confirm result:

@* <HxMessageBoxHost /> is in MainLayout.razor *@

<p>
	<HxButton Text="MessageBox.ShowAsync()..." OnClick="OpenMessageBox" Color="ThemeColor.Primary" />
	<HxButton Text="MessageBox.Confirm()..." OnClick="OpenConfirm" Color="ThemeColor.Primary" />
</p>

<p>
	ShowAsync result: @showResult.ToString("g")<br />
	Confirm result: @confirmResult
</p>

@code
{
	[Inject] protected IHxMessageBoxService MessageBox { get; set; }

	private MessageBoxButtons showResult;
	private bool? confirmResult;

	private async Task OpenMessageBox()
	{
		showResult = await MessageBox.ShowAsync("Info", "This is the text", MessageBoxButtons.OkCancel);
	}

	private async Task OpenConfirm()
	{
		confirmResult = await MessageBox.ConfirmAsync("Confirm", "Do you really want to ...?");
	}
}

Required setup #

You should place the HxMessageBoxHost component to MainLayout.razor (or App.razor) to make it work!

@inherits LayoutComponentBase

<HxMessageBoxHost />

@Body

Register required services using services.AddHxMessageBoxHost() from Startup.cs (Blazor Server) or Program.cs (Blazor WebAssembly).

public void ConfigureServices(IServiceCollection services)
{
	// ...
	services.AddHxMessageBoxHost();
	// ...
}

No heading #

If you clear the Title, HeaderTemplate and set ShowCloseButton="false", the header won't show up.
