Answer 1

If your requirement is only to get content from another page (and not need to display it in a new window), then perhaps this NuGet package will do what you need: AngleSharp .

Here is example code from the GitHub page:

var config = Configuration.Default.WithDefaultLoader();
var address = "https://en.wikipedia.org/wiki/List_of_The_Big_Bang_Theory_episodes";
var context = BrowsingContext.New(config);
var document = await context.OpenAsync(address);
var cellSelector = "tr.vevent td:nth-child(3)";
var cells = document.QuerySelectorAll(cellSelector);
var titles = cells.Select(m => m.TextContent);

Answer 2

make ajax call to retrieve the html.

$.ajax({ url: "Website url", success: function(result){

  $("#dvWebsite").html(result);

  

});
