I want to capture events generated by control tabs from library.

You probably want to capture the Deactivated event of the Window.

We are using the windows form application on a tough pad (touchscreen device).
want to show the on screen key board when user click the text box or any input control , rather then handling this event is there any way to handle this on the application level to show and hide the windows on screen keyboard
DevExpress editors, as well as regular .NET editors, do not affect OnScreenKeyboard's behavior. I suggest that you use one of the approaches described here to display it - Automatically pop up tablet touch keyboard on WinForms input focus.
I'm trying to programmaticly (from my own application) press a button that is located on another running windows (WPF) application.
Todo so, a handle to the button would be needed. There are plenty of posts about how to get such a handle.
However, it seem that WPF applications don't present handles for their graphical components:

Any clues on how to achieve an automated press on a button in such an application?
I don't have control of the source code for the application with the button.
I believe you'll need to look into UI Automation https://learn.microsoft.com/en-us/dotnet/framework/ui-automation/ui-automation-overview
I need to disable a button from a third-party winforms application.
I got the buttons handle using Windows API and WinSpy++, and i have no problem disabling it.
That button is in a DialogBox control. My application is also a winforms app.
How can i be notified when the dialog box appear, so i can disable that button?
Is there an event that can fire when it appears or any workaround?
Thanks guys!
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.
i have application with one form, which i developed in c#. I would like to hide the form when a user clicks somewhere else then on the form or on the notification icon (in system tray). How could i do that?
I am not 100% sure you can do it with the standard event exposed by Visual Studio in the designer but if you could attach to the DeActivate event, or form lost focus, then you can call form.Hide
