Click event not working for Firefox but is for chrome

The click event is not firing in firefox but works ok in chrome.
The test fails with the error: "Element not found on page."
Below is the code and HTML for the button I want to click.
Browser.ElementClickById("ctl00_ContentPlaceHolderBody_lvProducts_ctrl0_ctrl1_btnAddProductToCart_input");
and inside the elementclickbyid i have:
driver.FindElement(By.Id(elementID)).Click();
HTML code is:
event

You could try working around with a Javascript click.
// declare JS executor
var executor = (IJavaScriptExecutor)Driver;
// locate the input
var input = Driver.FindElement(By.XPath("//input[#type='submit']"));
// execute JS to click
executor.ExecuteScript("arguments[0].click();", input);
I've seen cases where regular Click(); does not work across browsers -- these cases are rare, but using JS click usually works across multiple browsers when I run into this issue.

driver.findElement(By.xpath("//input[#type='submit']")).click();
i am sure you are trying to use browser class to keep your methods there, but try to use xpath not id. just use this code to click what you need. don't use page object model or anything else. don't save it in your browser class under click method. just in your main code use this code to click. and before to run it make sure that you have only one type submit. if its gonna show to you 2 types then use this code
driver.findElement(By.xpath("//input[#type='submit'][1]")).click();
number 1 says click to first submit if the button which you need second then follow the logic and change the number to 2
driver.findElement(By.xpath("//input[#type='submit'][2]")).click();
for better answer share your code class and also URL where you are trying to click button and also which element you are trying to click

C# write in textbox in a web from url

I'm working on a project in c# .net where I have a website, on the page is a textbox
I have some qr codes that link to this page
when a particular qr code must fill in a text box.
it is possible to write a ULR that can automatically fill in the textbox
ex page.com(insert to tbxOne:"123")

How are you getting the QR codes?
Without code I can't be too much help but you could try come if the following things.
Document.getelementbyid(#id).innerhtml("text");
This will allow you to set the text of an element on the webpage.

Check extension of choosing picture in SP 2013 Picture Library

I need to check pictures extension when user has chosen picture and try to upload it into picture library.
I've found the way to edit master page with js script, but i haven't to edit master page. Then i try to use event receiver Adding, but it can't get the name of file or file path. I used:
var file = properties.ListItem.File.Name; //properties.ListItem - returns null
AfterProperties also returns null.
The another way i see is to edit Adding Picture form with js:
I think is's simplest way but i can't found information about it.
Problem: how to set js script to the form (see picture) or how to do such actions with another way

It can be realized with event receiver ItemAdding and with
properties.AfterUrl
The same answered question with code in:
Customizing upload file functionality in SharePoint picture library

In your case, a simple JS form validation will do.
First I would prevent default action of the submit button.
Then, I would analyze the contents of the filename textbox and check the extention. If it's not one of the listed in the validation script, return false + alert "THis file extention is not supported".
Why would you want to use event receiver? It catches the event on server side.

Selenium Webdriver: can't submit text into textbox area

I've been stuck trying to do some automating tests with AOL mail service (sending text messages). I want to insert text into a textbox and submit it but it fails all the time. In AOL web interface, I have to type the message, then hit "Enter" to submit or send it.
Here's how the textbox looks like:
<div id="dijit__Widget_66" class="inputContainer" layoutalign="bottom" data-dojo-type="ws/widget/Pane" widgetid="dijit__Widget_66">
<textarea class="wsInput" tabindex="201" data-dojo-attach-event="onkeyup: onKeyUp, onkeypress: onKeyPress, onblur: onBlurTextarea" data-dojo-attach-point="messageInput" style="width: 316px;"></textarea></div>
My code of selecting and inserting text into textbox area works fine:
IWebElement ele = driver.FindElement(By.CssSelector("div[id*='dijit__Widget'].inputContainer>textarea.wsInput"));
ele.Clear();
ele.SendKeys("Hello");
But thing turns to be complex when I want to submit the text, neither of these work:
ele.Submit();
ele.SendKeys(Keys.Enter);
SendKeys(Keys.Enter) only adds a new line into the textbox instead of submitting and sending the message.
I'm desperately looking for help!
**I've discovered that the command Keypress - Value: "013" (Enter key) in Selenium IDE works. But it only works with Selenium IDE, when exporting to Webdriver, I receive this error:
// ERROR: Caught exception [ERROR: Unsupported command [keyPress | css=div[id*='dijit__Widget'].inputContainer>textarea.wsInput | 013]]

Way too late for this post but for anyone else looking to solve this. Check and see if there is a function or event that is triggered when you submit text to that specific field. If there is, see if you can remove it by executing a script on the IDE.
It will look something like the image below:
Here's how you can remove events using JS:
document.getElementsByTagName('input')[input_index].attributes.removeNamedItem("eventname");

Have you tried using TAB, not sure if this will work but you can give it a try :
ele.SendKeys(Keys.Tab);

How to stop users from manually editing file path in HTML file input control?

I have a asp.net form with 5 HTML file input controls with runat=server and a submit button. after user selects the files and clicks the submit button, the files are upload in the server.
Problem is the HTML file input controls are editable, and user can edit the path after he has already selected the file from the browse button.
If he enters a invalid file path, the file is not uploaded because it does not exist.
How can I stop users from manually changing the file path? I have tried to make the controls read only, but it disables the browse button also.

You can't. Write your server side logic to cope with missing uploads.

you could try something like having a hidden field and when the user selects the file from browse, it populates to the hidden field as well. Then when they upload, you either read from the hidden field for your upload or using JS replace the values back to the original control and read from that.

Is this what you want to have...
You can do like that hiding the control when user select the file
and showing only the path to the user
in a div
if he disagree, let him click on a link called Choose Another next to the path div, so when user click Choose another toggle the same div with flushing the previous value
see this fiddle : http://jsfiddle.net/T2D3X/

While brian's suggestion works (Thank you brian for this), finally we decided to follow the server side handling approach. since in case of invalid file, the file size would be zero, so the response is instant and we do not need to wait till the file is uploaded because in this case there is not file in the first place.
//check if file exists
if (uploadCtrl.PostedFile.ContentLength > 0)
{
uploadCtrl.PostedFile.SaveAs(fileNameWithPath);
uploadCtrl.Dispose();
}
else
{
fileNameWithPath = "invalid";
}

You can also use these methods:
One before validating: http://jsfiddle.net/T2D3X/1/
One After validating: http://jsfiddle.net/T2D3X/2/
Friend of mine posted the same answer before I have re-modified it.
There are some internal jsfiddle error on second link you can ignore that, i have just added more functionally to check on submit what value exactly you are sending.
Let us know if you find the it helpful ;)
Thank!
