“Type” text in HTML textfield/textarea component with .NET

Question

I am trying to fill a web form from my .NET app using this code:

currElement.SetAttribute("Value", "some value");

But this just pastes the text in the web browser without firing any events. I need to fire three events in the appropriate order:

Keydown, KeyUp, Keypress

I already have these.

currElement.RaiseEvent("onChange");
currElement.RaiseEvent("onClick");

But I need more help on those mentioned events. Can anyone help me please?

If you want to capture key stokes in IE then use Javascript like this one.

Hello, Am trying to simulate typing in the webbrowser control input and textarea, so a normal typing will fire the events i have just mentioned at the onset, instead of just settting the value of the control to the text thanks

Hi Oghenez,

If you want to simulate typing in the webbrowser control, you can try use getElementsByTagName method and HtmlElement.InvokeMember Method. You can try the sample below.

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            HtmlElementCollection col = webBrowser1.Document.GetElementsByTagName("a");
            foreach (HtmlElement el in col)
            {
                if (el.InnerText == "Sign in")
                {
                    el.InvokeMember("click");
                }
            }

        }

Have a nice day.

Hi Oghenez,

If you want to populate fields in the webbrowser control, you can use the Document property of the WebBrowser control to access HTML DOM. You can try the sample below.

        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            mshtml.IHTMLDocument2 doc = (IHTMLDocument2)webBrowser1.Document.DomDocument;
            mshtml.HTMLInputElement ele1 = (mshtml.HTMLInputElement)doc.all.item("username", 0);
            ele1.value = "test value";
         }

Hope it can help you.

Answer 12

To simulate keyboard events use the SendKeys class.

Answer 13

Hello,

I found out that Sendkeys does not always work, it works some times , and at other times, does not do anything, so i quite using it
