Helo!

My goal is to retreive data from HPE Service Manager (HPSM). I use webBrowser component as it's seems the easyest way to me. At least I had no problem with authorization and opening search page but the things turned strange as I proceeded.

I need to find element with id "X13" on the page but

wb.document.getElementById("X13");

returns null although executing getElementById in IE and Chrome dev consoles still does the trick.

How can I find the element I need using C# and webBrowser component?

Are you waiting for the page to finish loading? – The Scrum Meister Jul 11 '18 at 08:27
Use htmlagilitypack lib, see [How to use HTML Agility pack](https://stackoverflow.com/questions/846994/how-to-use-html-agility-pack) – Nien Nguyen Jul 11 '18 at 08:32
are you sure your syntax is correct? your doing this in c# code correct? – Josh Stevens Jul 11 '18 at 08:32
Of course! To be sure here I event place my code in a button click handler. – Jhon Doe Jul 11 '18 at 08:33
what about wb.Document.GetElementDyId("X13"); In your c# code! the code you have above is JavaScript, your saying you are doing this in c# – Josh Stevens Jul 11 '18 at 08:34
HtmlElement he = webBrowser1.Document.GetElementById("X13"); – Jhon Doe Jul 11 '18 at 08:41
did that work?? – Josh Stevens Jul 11 '18 at 08:41
No GetElementById returns null in C# – Jhon Doe Jul 11 '18 at 08:42
The syntax was correct I just mistaked when retyping code here so the point is not about the syntax. Still thanks for trying to help. I even think it's some kind of protections HP uses to prevent robots to operate the application. – Jhon Doe Jul 11 '18 at 09:03
