C# WPF WebBrowser button click

I'm messing around with a WebBrowser in Visual Studio. I would like to create a button inside my main window that, when clicked, it clicks a button inside the WebBrowser. So basically I would just like to know how to press a button automatically using C#.
I have found several pages that tell me how to do this in WinForms, but I really want to do it in WPF and it seems like these things don't work there.

I don't really understand what you are trying to achieve (maybe you can try using another web browser or library for accessing html).
Anyway you can try to call javascript from WPF:
object[] codeString = {"alert('Replace this alert with javascript code you need');"};
object result = webBrowser.Document.InvokeScript("eval", codeString);

How can I open a webpage first and then fill in text boxes and click a button and visibly view the results?

[edit] It is a requirement that the webpage spawn and open in IE and allow user manual interaction after the programmatic actions have completed.[/edit]
I've seen a lot of code examples online about opening webpages or filling in webpage textboxes and getting a return value without ever opening them visibly.
I would like to open a webpage in IE, fill in a few textbox buttons
and then click the submit button and view the results visibly.
I am able to do this with a dll called Selenium, but I do not want to use a 3rd party application and it seems that WebBrowser() should be able to do this?
I can post my failed code examples if that would help.
Thanks.

Maybe this qould fit better as a comment, but I don't have enoigh reputation.
Do you know how HTTP-Forms work?
It would probably be easier to send a HTTP-Request to the target of the form you want to fill, including the parameters you would like to fill into the form.
So you don't need any WebBrowser or similar, just a simple HttpWebRequest object, where you specity the target, the method (very likely POST) and the data you'd like to send.

You can use the webbrowser control in Winforms. It is possible to access every DOM object of the website using the control. No need to open the IE externally.
You just need to specify the webbrowser URL as your link.
Then, fill the textboxes with code,
BrowserID.Document.GetElementById("TextboxID").SetAttribute("Value", "NewVaue")
Also, you can click on the button using InvokeMember("click").
There are lots of stuff using WebBrowser. You can learn it here.

Window not found exception comes when switchTO().Window("windowname") is used

I am using Selenium webdriver for Automation in c#, In the web page I have a button,when that is click new IE pop up gets opened, now i want the webdriver to continue the clicks for that new IE window pop up;
[Note:- The Child IE pop up is complete new .aspx page the window name of that i Checked by doing View Page source after right click and that is window.open("../Reports/MidWayReport.aspx");]
after a button click i tried following code.
webDriver.SwithTO().Window("windowname");
but that is generating "No window found exception.

It's likely a timing issue - try waiting a couple of seconds before trying to switch to the window.

It's either a timing issue or you haven't named the window. I think by default all new windows that aren't specifically named get the name _Blank. That may have changed as it's been years since I've looked at that across multiple browsers. However, there is an easier solution just name the window.
window.open("../Reports/MidWayReport.aspx", "MyWindowName");
Then you can do something like this
webDriver.SwitchTo().Window("MyWindowName");
This used to be set by a link that opened a popup like this
Open Window
However since you are doing this via javascript I provided the way to do that first. Here is a link to explain: http://www.infimum.dk/HTML/JSwindows.html

WPF WebBrowser control. need to prevent it from closing within an app

I have a WPF where I am implementing a WebBrowser control and I have a list of objects that when i select them it changes the url binding for the webBrowser control and all is well.
However, if the web page I am on tries to close the Webpage, a dialog pops up where you can hit yes or no to close the "window" (the WebBrowser control)
If the user hits "yes" then the web browser control is closed and exceptions are thrown when you try to select something else in the list because the window doesn't exist anymore.
The webbrowser control does not have a method for closing exposed where i can get to it and I was able to override the "Window.Close()" method but that also prevented me from closing the main app window.
I have tried inheriting from the WebBrowser class but it is sealed so I can't inherit to add event handlers or override methods such as "Close()" or events such as "OnClosing()"
I have no control over the website because it is a third party product.
Also, the WebBrowser control is not cancelling navigation when exiting.
so my question is
A. Is it possible to intercept the dialog and always answer "no"?
or
B. Is there another way to prevent the WebBrowser control from closing even if the person says "yes" to the dialog?

So, I ended up putting the control in it's separate view and then constructing and destroying the view as a dialogue

Once I had to solve a similar situation. It was a Delphi application, with an embedded TWebBrowser component, which is essentially the same thing as the WebBrowser of .NET. The software automatically clicked on elements of the webpage, and there was a case when after the click a confirm dialog popped up. The simplest way to press the OK button automatically was to call FindWindow with the parameters of the confirm dialog, and use the window handle to send it an Enter key press by calling SendInput. I think in your case an Escape key press is needed.

How do I create a Popup Dialog box in Silverlight?

I'd like to create a popup dialog box in silverlight in which i can manipulate controls, enter data, and return a value. I want it to be modal, so that when it is open, the page "Below" is inaccessible. I havent found an easy way to do this yet. Any suggestions?

I know the question asked for a Silverlight 2 solution but in Silverlight 3 (Beta now, RTW in July 2009) there is a built-in ChildWindow that can do everything you're looking for.

I haven't found a perfect solution either. The closest I have seen is this:
Using Popup to create a Dialog class
If it is ok to be non-modal, you can try this tip using HtmlPage.PopupWindow().
How to Popup a Browser Window

I'm new to the Sliverlight framework and am just starting to figure it out, but I have a similar need for a popup modal dialog box. I just tried an idea that looks promising:
I created a Rectangle (named "Shield") that covers my entire application area. It exists on top of everything in the main app. I set the fill-brush to White, and the opacity-brush to 81% so that the main app contents show through, but lightly (as in disabled). Then make sure the "Shield" is hit-testable. Now, when the "Shield" is visible, it will also, in effect, block all input to the controls below (at least from the mouse, haven't tried keyboard yet). When the app initializes, set the "Shield" visibility to Collapsed. In that state it won't block input to the main app.
The dialog box is then constructed on another canvas element that exists in the z-order on top of the shield. Normally the dialog box will be invisible, but when I need it, I just set the "Shield" to visible, and the dialog to visible. Since the dialog is on top of the "Shield" I get a very modal-like behavior. When the dialog box is closed, make both the dialog canvas and "Shield" canvas invisible again and the main app is again active.
I'm sure this the most brute-force way of doing it and that I will eventually zero in on a more elegant construct, but it works for now.

A more elegant solution is here:

I had the same requirement and ScottGu's Building a Basic Modal Dialog Using a User Control was the best solution that fit my requirement.

Here's a free library that provides one: http://www.vectorlight.net/demos/popup_dialogs.aspx
