I am using Webview to displays an html page that contains 2 inputs of type text and a submit button.I want the app user to be able to fill these fields on the app before launching the webview.Therefore taking the user directly to the result of the search.
Apparently the webview.Document is no longer available.
Any suggestion ?
Once the HTML is loaded into WebView, you can call a method called InvokeScriptAsync through which you can invoke some kind of Javascript.
await myWebView.InvokeScriptAsync("eval", new string[] { "var elem = document.forms[0].submit();"});
This way you can fill the input field, click a button or whatever you need.

I am making use of the GeckoWebbrowser control in a C# Windows forms app environment.
I am wanting to call the click event on a button on the browser page, from a code event behind.
When I try an access a specific button I can find it by making use of the GetElementById command, however after assigning this information to the GeckoInputElement to call the click event, there is a null reference exception visible with this.
My code call to get the element looks like this:
GeckoInputElement betbt = new GeckoInputElement(wBrowser.Document.GetElementById("bet-bt").DomObject);
If I assign it like this I can access the element but still cannot click it with the GeckoElement object:
GeckoElement g1 = (GeckoElement)wBrowser.Document.GetElementById("bet-bt");
The HTML for the button looks as follows:
<button data-action="bet" id="bet-bt" class="action">Bet</button>
GeckoInputElement's are for Html Input elements.
Just use GeckoHtmlElement:
GeckoHtmlElement g1 = (GeckoHtmlElement)wBrowser.Document.GetElementById("bet-bt");
GeckoElement and GeckoHtmlElement exist to differentiate when the browser is displaying non html.
For Html documents always use GeckoHtmlElement.
I have an HTML page with this script:
<Script>
function Run()
{
alert("The Content Here");
return true;
}
</script>
<button onclick="Run();">I Want It Now</button>
Lets say that I opened this page with firefox or Chrome. And lets say that I clicked on the button "I Want It Now" and the page shows me the alert:
The Content Here
How can I insert the alert content into a string in my VB.NET project? I know that I can use the alert window handle to get the label handle and then extract (grab) the text of the alert, but I don't think that this is the best way to do it. Is there another way to pass (or get) information from the page (not from webbrowser control or by using webClient.DownloadString) into my VB.NET (or C#) project?
i don't this it will easy to use js without the webbrowser control by the way if you changed your mind and want to use a web browser control , you can do it like this :)
WebBrowser1.Document.GetElementById("NAME").InvokeMember("click");
I'm creating a web browser. On the "mainpage" it has a button that takes you to the homepage, i'd like to give the user the option of changing the home page on "page1" (settings). on page1 I have "textBox1"(where the user enter desired homepage) and "button1" (set). Could you help me set this up? Is there a way where doing that action can change the source of webBrowser1?
First I would suggest you to download this Programming Windows Phone 7 ebook and explore it to learn Windows phone programming before asking StackOverflow.
Coming to your question,
Create a Settings class in the project and Add a static string property named something like "HomePageUri". Then in your Page1, add the source uri to that "HomePageUri".
Then in your main page, in the OnNavigatedTo event update the WebBrowser's source or you can bind the WebBrowser's source directly to the "HomePageUri" property
Good luck
I need help with connecting to a certain website via my username & password.
With WebClient I can fill the username field and the password field, but how do I invoke the click method of the button?
And How can I fill a specific textBox that doesn't have an ID?
I tried doing this with webBrowser, but every time I navigate I have to use a new function every time, which makes the work much harder.
Thanks.
What you're trying to do is wrong. If you want to Post some data to a web address (a URL), simply create a web form (a simple HTML form), fill it, and then send it. Just consider these notes:
Your HTML's form action should be the exact URL of the form you're imitating.
Your input controls should have the same name attribute value.
For more information, see Form Spoofing
Look at the web browser control and see if you can use that inside your windows form to perform the task that you are doing. Once you are satisfied with the results, you can make the web browser control invisible, and it'll work just like you do with web response and request calls.
View the source code and find the id of the button (say "Login").
Then use:
HtmlElement elem = webBrowser1.Document.GetElementById("Login");
if (elem != null)
elem.InvokeMember("click");
I am designing a winforms based testing app (which is based upon WatiN). I specify a page to test and the value to insert into a textbox, and then click the corresponding button.
Is it possible to add a query string to the request I make (when clicking button) and then get the URL of the next page? Based on this, I need to screen scrape it.
Not sure about Watin syntax, but in Watir (Ruby version) you can get URL of the page displayed in browser with
browser.url
Or do you need to get URL of the next page before you open it?
Based on your comment to AmitK, Ċ½eljko's answer is right.
In WatiN (and C#), the syntax is:
Console.WriteLine("The current page is:" + ie.Url.ToString());
(just in case: 'ie' is the browser reference, use whatever object you use to enter text and click buttons)
What exactly do you mean by "next page" ? Does the form when submitted redirect to another page? If so, you will receive a HTTP 302/303 status code with the URL of the next page.
