Stop page load during navigate url in selenium

I am using selenium tool in my C# windows application,
driver.Navigate().GoToUrl(baseURL);
when the the application executing this line the page loads takes 2mins.
During that time, the followin element has found within 10 sec.
driver.FindElement(By.Id("searchTerm"))
I used driver.FindElement(By.Id("searchTerm")).SendKeys(Keys.Escape);
But it wont work properly. The problem is after complete the page load then only the control execute next line . But I need to stop the page if the element has found.
Thanks

You could try issuing the Escape press at the top level, not on the element itself:
if (driver.FindElement(By.Id("searchTerm")) != null) {
Actions action = new Actions(driver);
action.SendKeys(Keys.Escape);
}
That seems to be the most common way of issuing a page load stop.

To stop page load at any moment you can use something like this:
IJavaScriptExecutor js = Brwsr.Instance as IJavaScriptExecutor;
js.ExecuteScript("window.stop();");

WebBroswer_DocumentCompleted event is not working

I have a form with a browser control. (this control uses IE9 because I set values on registry editor)
This web browser navigates to a specific URL and fills all fields on HTML page and submit them, then result page is displayed.
My problem is that i just want to know when this reslut page is fully loaded or completed so that i can fetch some information.
I use WebBroswer_DocumentCompleted event which works fine for the first page but not for the result page as it triggers before result
page is loaded.
I tried other solution which is to check the div tag inside the result page (this tag only appears when result page is loaded completely) and it works but not always.
My code:
private void WebBroswer_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
HtmlElementCollection elc3 = this.BotBrowser.Document.GetElementsByTagName("div");
foreach (HtmlElement el in elc3)
{
if (el.GetAttribute("id").Equals("Summary_Views")) //this determine i am at the result page
{
// fetch the result
}
}}
That div id is "Summary_Views".
I can provide you the link of that website on demand which is just for BLAST tools and database website for research purpose.

Frames and IFrames will cause this event to fire multiple times. Check out this answer:
HTML - How do I know when all frames are loaded?
Or this answer:
How to use WebBrowser control DocumentCompleted event in C#?
Or ms's kb article:
http://support.microsoft.com/kb/180366

Do you know if there are frames? If so then please say so, so people can help with that. If not then say so, so people can offer alternatives.
My guess is that the content is being generated by JavaScript. If it is then the document is complete before the JavaScript executes and you need to somehow wait until the JavaScript is done. The solution depends upon the web page. So you might need to process multiple document completes for diagnostic purposes and attempt to determine if there is a way to know which one you need.

At last i have solved my problem. I put a timer control from toolbox and set its time interval to 200ms and its Autoreset property to false. I set a tick event which has a code to check every 200ms whether this Div has been loaded or not, after that, Autoreset property is set to true.This solution is working perfectly :)

Page back not working as expected on BinaryWrite

I have a home/main menu page. There's a link to the form. If you run the form with inputs, you get Excel output. If you click 'open' to open that output in the browser, the back-button takes you to the home/main menu.
Which is understandable, since if the form page is X.aspx, the binaryWrite that outputs the Excel doesn't really change that.
The problem is that if there's a postback, the back button takes you to the form page. This is inconsistent. If I run the page or a drop down causes a postback, I really want the back-button to take me to the form field, so that I can run the excel sheet again.
Things I've tried.
I tried adding a location header.
e.ContentFileName = "ELTFile.Output.xls";
Before the response.Writing ...
private void SendFileToBrowser(DownloadFileEventArgs e)
{
if (!e.Cancel && e.FileObject != null)
{
this.Page.Response.Clear();
this.Page.Response.ClearContent();
this.Page.Response.AddHeader("Content-Disposition", string.Format("inline; filename={0}", e.ContentFileName));
this.Page.Response.AddHeader("Content-Length", e.FileObject.LongLength.ToString());
this.Page.Response.AddHeader("Location", e.ContentFileName);
this.Page.Response.ContentType = e.ContentType;
this.Page.Response.BinaryWrite(e.FileObject);
this.Page.Response.End();
}
}
And I tried
Response.Cache.SetCacheability(HttpCacheability.Public);
As well as
Response.Cache.SetCacheability(HttpCacheability.Server);
But basically, depending on whether or not I post back before I click the 'Submit' button to generate the Excel, I get the main menu (don't want) or the form page (want). I want the form page every time. Basically I want to tell the browser "I know it's not really a different page, but treat it that way, will ya please?"

You cannot directly add pages to a browser history.
You could make your application such that the form is always a page ahead of the excel output.
To do this, have a separate page to output the excel.
When you have the inputs to generate the excel, Response.Redirect to the generation page.
This will keep your input form in the browser history.
Note: you could redirect to the same page too if you liked, but that would need you to track it.

C# Webbrowser navigating links in order

I'm trying to teach myself C# and to start I'm trying to convert a program I originally wrote in Autoit.
I'm using a Windows Application Form and the program is suppose to take one or two links as input. Navigate to those to pages, grab some links from a table, then visit each of those pages to grab some content.
If only one link is entered it seems to go to that page and grab the links from a table like it is suppose to. If two links are entered it seems to only grab the links from the second table.
So if two links are passed this method
private void getPageURLList(string site1, string site2)
{
getPageURLList(site1);
getPageURLList(site2);
}
Calls the same method that gets called when there is only one link
private void getPageURLList(string site)
{
webBrowser.DocumentCompleted += createList;
webBrowser.Navigate(site);
}
I'm pretty sure the issue is "Navigate" is getting called a second time before createList even starts the first time.
The reason I am using WebBrowser is because these pages use Javascript to sort the links in the table so HTTPRequests and the HTMLAgilityPack don't seem to be able to grab those links.
So I guess my question is: How can I keep my WebBrowser from navigating to a new page until after I finish what I'm doing on the current page?

You have to make a bool variable to know when the first proccess has completed. And then start the other. Application.DoEvents() will help you.
Note that all this events run in the main thread.

In your documentcompleted event you do your link processing. At the end of the link processingyou tel the browser to navigate to the next url

Opening a browser and filling in some data

i want to know how i can open a browser to a specific web page and then fill out some of the content of the boxes on that page.
My idea is for someone to be able to order a particular item from our internal ordering system. The barcodes for these items are what will populate the fields on the page i want to open.
I no i can open a new instance of ie using Process.Start("IEXPLORE.EXE", url); howver how do i get a handle on that exact ie instance window so i can begin to add the required data to the fields?
Is this even possible?
Thanks very much

WatiN should help with this. I've generally used it for acceptance testing of web apps, but the principle is the same. Open a browser instance, reference stuff in the DOM, manipulate form elements, etc.

In addition to WatiN (as was suggested in another answer), you might consider a load testing package like Web Performance Load Tester. They have a free version that lets you run up to 10 virtual users at a time, which will perform scripted actions.
Another option would be to use a standard WebBrowser object to load your website. The WebBrowser object allows you to access and alter certain web parts. Below is sample code that automatically searches Bing:
private void LoadPage()
{
WebBrowser webBrowser1 = new WebBrowser();
webBrowser1.Navigate("http://www.bing.com");
//Wait for document to load...
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
//Set the text of the search input
HtmlElement txtTextField = webBrowser1.Document.GetElementById("sb_form_q");
txtTextField.InnerText = "My test text";
//Perform a click on the search button
HtmlElement btnSubmit = webBrowser1.Document.GetElementById("sb_form_go");
btnSubmit.InvokeMember("click");
}
