Dialog

Dialog objects are dispatched by page via the Page.Dialog event.

An example of using Dialog class:

using Microsoft.Playwright;
using System.Threading.Tasks;

class DialogExample
{
    public static async Task Run()
    {
        using var playwright = await Playwright.CreateAsync();
        await using var browser = await playwright.Chromium.LaunchAsync();
        var page = await browser.NewPageAsync();

        page.Dialog += async (_, dialog) =>
        {
            System.Console.WriteLine(dialog.Message);
            await dialog.DismissAsync();
        };

        await page.EvaluateAsync("alert('1');");
    }
}
note

Dialogs are dismissed automatically, unless there is a Page.Dialog listener. When listener is present, it must either Dialog.AcceptAsync() or Dialog.DismissAsync() the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.
