Accessing DOM Elements using CEFSharp in C#

I am working on a small project based on CEFSharp in C#.

I want to know the procedure to access DOM Elements using CEFSharp in C#. I have all initial things setup already, just need to access the elements. I know how to do this with the built-in web Browser of C# but I cannot find any proper information about doing this with CEFSharp.

I am using the following line of code to access the DOM element of the webpage in a button click listener (separate class than browser class).

private void button1_Click(object sender, EventArgs e)
{brow.chromeBrowser.ExecuteScriptAsync("document.getElementsByName('q').value='Hello';");
}

where brow=CEF browser class object, chromeBrowser=browser instance

With the above code modified like ("alert('My Message')"), I can get an alert message easily with the JavaScript, no problem with that, but I want to access a specific element of DOM, and here nothing works.

Well I found the answer by myself, just a slight change. Hope it helps someone else too

brow.chromeBrowser.ExecuteScriptAsync("document.getElementsByName('q')[0].value='Hello';");

It was a small typo in javascript line . I wrote [0] in the above syntax and everything worked fine. The textfield on the webpage got filled with my text (Hello) after my button click.
