How to get the clicked element using webview2 in windows forms

I have a query in windows. forms I am new to this.
I have developed a form where users can open any website from it and upon right click of any element I am displaying the element name, id, and few attribute values in a data grid. For this, I have used webbrowser control.
However, I was facing some errors for a few of the sites so I tried to move to webview2. But here comes the issue
Earlier I used to get the element using the below code
HtmlElement element = webbrowser1.Document.GetElementFromPoint(e.ClientMousePosition);
But now I am unable to retrieve an element by using webview2.
Can someone please help me with this?

You will need to use JavaScript. You will need async methods.
Then, you can get the element by passing a javeScript string.
Point p = e.ClientMousePosition;
string jElement = await webBrowser1.ExecuteScriptAsync($"document.elementFromPoint({p.X},{p.Y})");
The result is JSON. You will need to parse the result to get the element name.
I am trying to figure out the same thing.

Not able to get all child elements from a modal window

I am trying to get access to a checkbox present in the modal window.
And check- uncheck it by using UI-automation/uiacomwrapper.
I am able to do it, but in some application, it is failing.
For example, say Team Viewer. I am not able to get access to the checkbox present in the modal window.
var testi = win.GetWindowByName("TeamViewer");
var child_win = win.GetChildWindow();
var window = (AutomationElement)child_win.Element;
var cb = window.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Start TeamViewer with Windows"));
it should return some value in cb, but it is returning null.
The same code is running fine with other windows form and WPF applications.
Only in case of Team Viewer, it is returning null.enter image description here

I am not 100% sure here as I do not use Team Viewer.
NameProperty would find elements whose Name matches your input. Usually the name is something that makes sense to the programmer. You might have to iterate over the elements and pick one whose caption matches your query.

How to get page name with webBrowser

Try to code with WPF. Currently I want to implement a simple webBrowser, and now I'm stuck. I want to get name of opened page (Every tab has name according to opened page), but I can't find the solution. In C# I can use this code:
TabControl.SelectedTab.Text = webBrowser.Url.Host.ToString();
But with WPF it doesn't work.
What is solution to find page name with WPF?

Please try like this,
TabControl.SelectedTab.Text = webBrowser1.Url.AbsoluteUri;

Getting TextBox data from a control hosted in Winforms

I've created textboxes to use them in winforms - the textbox is done in wpf and integrated in the form. The problem is when I input some text in it, it doesn't really "read" it. The name of the textbox is elementHost1, and if I go like this:
string input1 = elementHost1.Text;
and I write something in the textbox, it's not shown in the string. Is there something wrong in the WPF code? I checked for something saying "IsReadOnly" but there wasn't anything like that.

No, the name of the ElementHost is elementHost1. The text box is hosted inside of that. You'll need to get at the actual object inside the element host in order to get at the text.
To do that, access the .Child property to get at the textbox hosted inside the ElementHost:
var elementHost = this.elementHost1;
var wpfTextBox = (System.Windows.Controls.TextBox)elementHost.Child;
var text = wpfTextBox.Text;

Have a look at http://msdn.microsoft.com/en-us/library/ms742215.aspx, which describes how to send data back to the WinForms host application.

C# jumping some textfields like searchboxes

I'm just using watin to fill some textfields but sometimes it writes in the wrong textfield because the textfields name is not clear here's my code
IE browser = new IE(site);
browser.TextField(Find.By("type","text")).TypeTextQuickly(username.ToString());
browser.TextField(Find.By("type", //"password")).TypeTextQuickly(pass.ToString());
browser.Button(Find.By("type", "submit")).Click();

Edit your HTML code and setup ID´s for your input elements. Then use Find.ById

One option could be to see if there is an outer element (such as a Div) you can find first, and afterwards get the text fields from that element instead of from the browser variable. That could for instance look like this:
Div div = browser.Div(Find.ById("divId"));
//Div div = browser.Div(Find.ByClass("divClass")); // or like this for instance...
TextField text = div.TextField(Find.By("type", "text"));
TextField password = div.TextField(Find.By("type", "password"));
Button submit = div.Button(Find.By("type", "submit"));

I am unclear as to your knowledge of WatiN and testing so I will start from the begginging. First you need to go on the webpage you want to test and (in IE) go to tools -> Developer tools. Click the white arrow in the menu then proceed to click the box you wish to utilize. Once you do this the developer tools will give you the code for the textbox including many ways you can reference it in your code. For example, using dev tools in IE I can automate logging into my gmail like this:
IE browser = new IE("https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=http://mail.google.com/mail/&scc=1&ltmpl=default&ltmplcache=2");
browser.TextField(Find.ByID("Email")).TypeText("myemail#email.com");
browser.TextField(Find.ByID("Passwd")).TypeText("mypassword");
browser.Button(Find.ByID("signIn")).Click();
There are many Find.By commands so there is no reason you can't acess ANY textfield you wish. You just need the html and to be specific to which one you want to write into. I hope this helps :)
