IDialogService

The IDialogService provides methods for displaying modal dialogs to the user, including confirmation prompts, error messages, informational notices, success notifications, and warnings.

Injecting the Service

Inject IDialogService into any Blazor component via property injection. Note that this is the PowerPortalsPro dialog service (PowerPortalsPro.Web.Blazor.Services.IDialogService), not the FluentUI dialog service.

using IDialogService = PowerPortalsPro.Web.Blazor.Services.IDialogService;

[Inject]
private IDialogService _dialogService { get; set; } = null!;

Confirmation Dialogs

Use ShowConfirmationAsync to prompt the user with a yes/no question. The returned DialogResult.Cancelled property is true when the user selects the secondary (negative) option.

var result = await _dialogService.ShowConfirmationAsync(
    "Are you sure you want to delete this record?",
    title: "Confirm Delete",
    primaryText: "Yes",
    secondaryText: "No");

if (!result.Cancelled)
{
    // User confirmed — proceed with deletion
}

Message Dialogs

Use the following methods to show single-button message dialogs with different visual styles:

• ShowInfoAsync — Informational message with a neutral icon.
• ShowSuccessAsync — Success message with a green checkmark icon.
• ShowWarningAsync — Warning message with a yellow warning icon.
• ShowErrorAsync — Error message with a red error icon.

await _dialogService.ShowInfoAsync("The operation completed.", "Information");

await _dialogService.ShowSuccessAsync("Record saved successfully.", "Success");

await _dialogService.ShowWarningAsync("This action cannot be undone.", "Warning");

await _dialogService.ShowErrorAsync("An error occurred while saving.", "Error");

Common Parameters

All dialog methods accept optional title and primaryText parameters. If omitted, localized default values are used. The confirmation dialog also accepts a secondaryText parameter for the cancel button label.

Dialog Result

All methods return a DialogResult object. For confirmation dialogs, check the Cancelled property to determine the user's choice. For message dialogs, the result indicates the dialog was dismissed.
