Using window.open method we can open new browser  window and close window.
window.open Method  :
1.The syntax of the window.open method is given below:
open (URL, windowName[, windowFeatures])
A> URL :The URL of the page to open in the new window. This argument could be blank.
B> windowName :A name to be given to the new window. The name can be used to refer this window again.
C> windowFeatures :A string that determines the various window features to be included in the popup window (like status bar, address bar etc)
Example 1>window.open ("http://www.google.com", "mywindow","location=1,status=1,scrollbars=1, width=100,height=100");
          A window with location bar, status bar, scroll bar and of size 100 X 100.
Example 2>window.open ("http://www.google.com","mywindow","menubar=1,resizable=1,width=350,height=250");
          A window with menu bar. The window is re-sizable and is having 350 pixels width and 250 pixels height.
Example 3>Moving the window to a desired location :
          We can use the window.moveTo function to move the popup window to a desired location.
          The code below shows positioning the popup at a desired location.
         window.open("http://www.google.com", "mywindow", "location=1,status=1,scrollbars=1,  width=100,height=100"); 
         mywindow.moveTo(0, 0); 
Example 4> On button click we can open new window using window.open method as follow:
            private void btn_Click(object sender, RoutedEventArgs e)
            {
              HtmlPage.Window.Eval("window.open('http://www.google.com');");
            }
           To pass querystring to the URL :
            public string Name;
 
            private void btn_Click(object sender, RoutedEventArgs e)
            {
              string h = "window.open('http://www.google.com/finance?q=";
              h = h + Name + "');";
              HtmlPage.Window.Eval(h);
            }

window.close Method  :
The window.close () method could be used to close a window.
The close method closes only windows opened by JavaScript using the open method.
If you attempt to close any other window, a confirm message is displayed, asking the user to choose whether the window is to be closed or not.
If you have the reference to a window, you can use the reference to the window to close.
For example:
popup_window = window.open(""); 
popup_window.close ();

Example 1> On button click close the window :
           private void btnCancel_Click(object sender, RoutedEventArgs e)
        {
            HtmlPage.Window.Eval("window.close();");

        }
