I'm using WatiN testing tool and i'm writing c#.net scripts. I've a scenario where i need to change the theme of my web page, so to do this i need to click on a image button which opens a ajax popup with the image and "Apply Theme" button which is below the image now i need to click on the button so how to do this please suggest some solution.
So first click your button that throws up the popup, and .WaitUntilExists() for the button inside the popup.
IE.Button("ShowPopup").click()
IE.Button("PopupButtonID").WaitUntilExists()
IE.Button("PopupButtonID").click()
This may not work in the case the button on the popup exists but is hidden from view. In that case you could try the .WaitUntil() and specify an attribute to look for.
IE.Button("ButtonID").WaitUntil("display","")
The Ajax pop-up itself shouldn't pose a problem if you handle the timing of the control loading asynchronously. If you are using the ajax control toolkit, you can solve it like this
int timeout = 20;
for (i=0; i < timeout; i++)
{
bool blocked = Convert.ToBoolean(ie.Eval("Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack();"));
if (blocked)
{
System.Threading.Thread.Sleep(200);
}
else
{
break;
}
}
With the control visible you then should be able to access it normally.
Watin 1.1.4 added support for WaitUntil on controls as well, but I haven't used it personally.
// Wait until some textfield is enabled
textfield.WaitUntil("disable", false.ToSting, 10);
I'm not using any ajax control toolkit and in the popup there is no text field as i've mentioned there is only a image and a button below it, which i need to click in order to apply that image as theme.
I wrote a post about how I do ajax synchronization, since I was having problems with WaitUntilExists: http://lebobitz.wordpress.com/2011/03/06/synchronizing-watin-and-ajax-with-jquery/

i am facing an issue in winform app, i am using webbrowser control. At one point i am using for loop and in the loop i have to invoke the Enter button event programatically. It is something like below:
for (int i = 1; i <= 4; i++)
{
htmlElement = webBrowser1.Document.GetElementById(PagerTxtBoxID);
htmlElement.InnerText = i.ToString();
SendKeys.Send("{ENTER}");
}
now every time at SendKeys.Send("{ENTER}"); the page should gets refreshed with new values (inside webbrowser control).
However it is not working and the page is not refreshing and when i am trying ti debug, it shows changes are not allowed while code is running.
Requesting you folks to please guide me from here.
SendKeys.Send(...) actually send the keyboard signals as when you are hitting keys on whatever is focused now. If you are on debug, it probably tries to send enter key to visual studio, modifying the C# code. You have to figure out another way of interacting with the webbrowser. One method is to programatically click a html button.
I will try my best to express what I do not understand about WebForms. Maybe somone can explain it to me....
I work in 'quite big' WebForms (website) Application.
Application already has a PopUp (which I HAVE TO USE, because I dont have time to make a new one) like MessageBox in Winforms, but:
it's place is in MasterPage.master (I use it like ((MasterPage)Poup.Show("blablabla", yes_no));
I can add buttons to it and change style etc.
it doenst stop application (like .ShowDialog() in WinForms), so I have to assign onClick events dynamicly and assign/catch them on Page_Load to go to the wanted method depending on users input on form. At the moment i can't to anything about it.
And here is the problem:
Depending on form validation, if users press a button (on a form) - then form realods it's TextBox.Text's values and changes DropDownLists's SelectedIndexes and SelectedValues.
BUT IF YOU GO TO THE SAME METHOD WITH MY POPUP WINDOW:
ex: Do you confirm? YES/NO
If you press You press ANY button, then: CHANGES ARE VISIBLE BY CODEBEHIND BUT TEXTBOXES ARE STILL VISIBLE WITH PREVIOUS DATA ON THE SCREEN, ALSO DROPDOWNLISTS HAVE OLD VALUES SELECTED
BUT IF YOU PRESS A FORM BUTTON (WHATEVER WHICH), EVEN IF IT'S METHOD DOES NOTHING - ALL FORM WILL "RELOAD" AND HAVE PROPER DATA ON THE SCREEN.
(it's not about Runat="server" or AutoPostBack, I checked it)
I dont event know what to do about it :(
Update panels are used to partial refresh of some fields inside him, caused by certain triggers, like buttons, textchanged, etc.

(Haven't worked with web forms events in a while, just answering in case nobody else does.)
Out of curiosity, what happens if, in your javascript handler for your popop button, you getElementById one of the form buttons on the main page and call ".click()" on it?
The basic problem sounds like there's a runat/server form on the main page, with certain behaviors associated with it, which is submitted by the main page runat server buttons but not by your popup JS.
Easy enough to test with the above approach. If that works, take a step further and try to figure out why it worked, based on what those buttons are doing.
(If you're not using JS at all for the popup, then View Source the output HTML, because I'm sure it is. Backtracking those calls should help you understand the trace from popup button press to form submission.)
I probably mislead you by "OnClick", it's NOT javascript OnClick="method()" issue.
I mean ClickEvent on a button (in codebehind). For Ex. If form is validated I have to do:
ViewState["PopUpSelection"] = "yes_no";
(MasterPage)PopUp.Show("blabla",yes_no) //loads popup from MasterPage;
return;
then on Page_Load I have:
**if (string)ViewState["PopUpSelection"] == "yes_no"
{
ButtonConfirmYes.Click += new EventHandler(MyMethod);
}**
And if method "MyMethod" is called from a FORM button, everything "will go ok".
If you call the same method from PopUp button: changes are visible by codebehind, but on the screen nothing happens, unless i press ANY FORM BUTTON, whatever it does
Windows Form Application – Manipulating input-elements in WinForm WebBrowser
Although I am familiar with HttpWebResponse/HttpWebRequest to login to a website, I was trying it now via using the mshtml library and found some weird behavior and I would like to see if someone else might be able to help me out here..
I have an HTML login page with a java backend with a Username field, a Password field and a Button.
The logic is very basic, I have a built a winform app with a built in webbrowser.
At the Document_Completed event I use the following code to enter my settings and to click the button.
private void webBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (webBrowser.Url.ToString() == #"MyWebPage/signin")
{
HTMLDocument hdc = new HTMLDocumentClass();
hdc = (HTMLDocument)webBrowser.Document.DomDocument;
IHTMLElement elb = hdc.getElementById("login_button");
IHTMLInputElement elu = (IHTMLInputElement)hdc.getElementById("username");
IHTMLInputElement elp = (IHTMLInputElement)hdc.getElementById("password");
try
{
elu.value = "MyID";
elp.value = "MyPwd";
elb.click();
}
catch { }
}
}
Apart for this code being very quick and without error handling, it should do the trick and it does, partially..
There are two scenario's:
I launch the tool, it loads the webpage.
The tool populates the UserID field and the Password field correctly
The tool fails to click the button
I click the button manually, I am logged in, I click logout, I am back at login page
I immediatly logged in again, the tool enters the information
The tool immediatly clicks the button as well.
Is there anyone who might be able to explain me why this happens and how I could get around this with the current setup (hence not using HttpWebRequest). I don't see the difference between loading the page at startup or being redirected after logout, but apparently there is a difference in there or I am doing something wrong.
Any feedback on this matter is very much appreciated.
Thanks,
Kevin
EDIT:
I added a Button to my Windows Form that bas the same backend Code as below in order to click the button on the webpage, this works perfectly.
I triggered clicking this button in the webBrowser_Completed event but it doesn't work.
For some reason, everything I add to the webBrowser_DocumentCompleted event does not allow me to trigger the click event for the button in my WebBrowser control. Once that entire event has completed, if I then try to trigger it it works but I would like to automate this.. Any advice?
This might be a long shot and not the most elegant workaround but how about letting a backgroundworker run for a second in your DocumentCompleted event that then triggers the button that you clicked from it's seperate thread. This might just get this automated.
As this will run from a different thread, keep in mind that you might have to invoke certain controls so this might be another downside to this workaround..
If this doesn't work then, as Regfor previously suggested, Watin.org can help you out.
how about this :
HtmlElement button = webBrowser.HtmlDocument.GetElementById("login_button");
button.InvokeMember("click");
it works in my program.
I want to print a html file, though i do not want the browser to be visible, but i want the print dialog to be visible.
Thanks,
Horea
found the problem.
i have to wait for the event DocumentLoaded (or smt like that) to be fired, and then try the print.
thanks
So, just hide the WebBrowser control on your form:
myWebBrowser.Visible = false;
Of course, you can also set this property in the Designer if you never want the control to be visible.
I am using an AJAX CollapsiblePanelExtender for several sections of a form. I can collapse a panel programatically using the following 2 lines:
ajaxCollapsiblePanelExtender1.Collapsed = true;
ajaxCollapsiblePanelExtender1.ClientState = "true";
However, the expand/collapse animation does not play as when the Expand/CollapseControlID is clicked. It simply appears in the collapsed state. Is it possible to trigger this animation programatically?
You could open it by clicking the object with javascript/jQuery when you return from the server
I think this may be the only way to get what you want
