How to use EmulationSetTouchEmulationEnabledRequest class of PuppeteerSharp.Messaging package

Try adding the URL/Domain to Internet Download Manager's exception list. It will ignore the download request.

Just replacing navigation with WaitUntilNavigation.Networkidle2 worked to wait until Javascript is finished to excute.

using PuppeteerSharp;

await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
Browser browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = true // false if you need to see the browser
});
var page = await browser.NewPageAsync();
page.DefaultTimeout = 5000; // or you can set this as 0
await page.GoToAsync("https://www.google.com", WaitUntilNavigation.Networkidle2);
var content = await page.GetContentAsync();

Console.WriteLine(content);

If anyone needs it, here is the code I used below :

        Base64Image img = new Base64Image();            
        using (Page page = await parentPage.Browser.NewPageAsync())
        {                
            var tcs = new TaskCompletionSource();
            page.Response += async (sender, e) =>
            {
                string contentType = null;
                string[] imageMimeTypes = { "image/jpeg", "image/png", "image/webp", "image/gif" };

                if (e.Response.Headers.ContainsKey("content-type"))
                    contentType = (string)e.Response.Headers["content-type"].ToLower();

                if (e.Response.Headers.ContainsKey("Content-Type"))
                    contentType = (string)e.Response.Headers["Content-Type"].ToLower();

                if (imageMimeTypes.Any(t => t == contentType))
                {
                    img.ContentType = contentType;
                    

                    await e.Response.BufferAsync().AsTask().ContinueWith(async (data) => img.Bytes = await data);   
                    tcs.TrySetResult();
                }
            };
            await Task.WhenAll(page.GoToAsync(uri.AbsoluteUri), tcs.Task);
            await page.CloseAsync();
        }
        return img;

The execution of the GetCookiesAsync task needs to be awaited, like this:

private async Task YourMethod()
{ 
    var result = await page.GetCookiesAsync();
}

You might need to change your callers for this.

Try to read about asynchronous programming in C#: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/async/

So what you are seeing with this:

Id = 7315, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}"

is the async task not yet completed. GetCookiesAsync returns immediately. If you want to want to wait for the result, you should await it.

This code will load www.kayak.com with no images:

using (var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = false }))
using (var page = await browser.NewPageAsync())
{
    await page.SetRequestInterceptionAsync(true);

    // disable images to download
    page.Request += (sender, e) =>
    {
        if (e.Request.ResourceType == ResourceType.Image)
            e.Request.AbortAsync();
        else
            e.Request.ContinueAsync();
    };
    await page.GoToAsync("https://www.kayak.com");
    Console.ReadLine();
}

That's an array in the browser. If you want to get that array on your site, you can use the GetPropertiesAsync method. It should be something like this:

var properties = await elements.GetPropertiesAsync().ConfigureAwait(false);
var elementsArray = properties.Values.OfType<ElementHandle>().ToArray();

I found the solution to server side rendering of js and css on DOM files with chromium. Chrome can be run as headless providing the capability to render in the backend without it's UI. There's a library than can be used to drive chromium call peppetteer for Node js and PuppeteerSharp for .Net. Under .Net u can get it as Nuget Package and as for Node js its on npm .

So, after many tries and a lot of searched, I ended up switching to Selenium, which seems to have better documentation and a lot of examples here. This is the code, that worked for me:

string locator1 = "td:Contains(\'41818397111\')";
string locator2 = "td[id = \'InvoiceDetails\']";
IWebElement webElement = driver.FindElement(Selenium.WebDriver.Extensions.By.JQuerySelector(locator1).Parent().Find(locator2));
webElement.Click();

You should an object in your map

Array.from(document.querySelectorAll('{allResultsSelector}'))
   .map(f =>{ return { patientName: f.innerText} });
