I need to create a popup in a windows form. For example if an user tries to change anything in the windows form settings they should get a popup dialogue. In the form there are five toolbar buttons. If the user jumps into another toolbar and tries to save changes they should get a popup dialogue.
May you design a new form and use the ShowDialog() method. It will open the form as a modal window. You will not be able to focus something different until this window is closed. The advantage is that you're able to design this "Pop-up" by yourself.
If you want to show something like a short message, a MessageBox.Show() will do your job! For more information about MessageBoxes you better read the official MSDN page, especially the parts concerning the Show() method and it's overloads.
Use this
MessageBox.Show("Error message",
"Title of error");

In a WinForms app, I have a specific set of buttons inside a UserControl which I need to be intact always, even if a modal form is currently displayed.
I do not have control over the modal form appearing (can't change ShowDialog to simply Show). I wonder if there is any way to override/suppress the modality of another form.
Is there a way to do this?
I think the way to go is creating your own modal-form that will look like or share the same functionality as the uncontrolled modal form (I'm doing that a lot with message boxes for example)
Once you will do that, you will be able to call the modal form with 'Show()', and on the caller form, you will be able to determine what happen when your custom modal form will be shown (disable all controls instead of the user control that hosting the buttons you want to keep clickable).
If you cannot create your own modal-form as suggested, maybe you should consider invoking the user control and the uncontrolled modal with different executables (one can invoke the other) so it will work in parallel side by side on the screen. You can share the information between the two assemblies using named pipes for example.
I was wondering if there is a window property, for a wpf application, that disables any actions outside of the window. For example, when you open a message dialog and click outside of it, the message dialog background flashes. Kind of saying you can't do any actions outside of the message dialog untill you click the 'OK' button. I want that implemented in some windows that I open in a program i'm developing but can't seem to find any info on it. Looking for ways on how i might approach this.
Try ShowDialog() instead of Show()
Opens a window and returns only when the newly opened window is closed.
Window childWindow = new Window();
childWindow.ShowDialog();
Note that it will prevent clicks only on parent window(s). Clicks on other applications or Desktop can't be prevented by the Dialog.
I'm creating an add-in for Microsoft Excel that helps to automate some of my accounting processes. One of the pieces of the add-in is a ribbon tab with a button. Clicking this button opens a form with a list box that displays each account (worksheet) name and their respective balances.
The problem is that the rest of the controls in Excel are still tangible while the form is open. If, for example, a person were to change the name of the worksheet while the form was open, it may cause an error.
I noticed that message boxes render an application unclickable until they exit the screen. It isn't limited to just message boxes, either- I've seen the Nexus Mod Manager do the same thing when installing mods for games. I've seen it in many applications, but I haven't figured out how to do it myself.
My question is simple: how do I change the properties of a form such that the rest of the application is disabled until the form is closed?
What you need is a modal form. Opening a modal form will "block" the entire UI until it is closed, just like message boxes do.

i have a C# program that i made that uses forms to display the control for the user.
the main form open other forms on top of it, each new form is set to topmost
in the program i call for PDFCreator in order to make a new PDF file, but i can't see the dialog becouse of the form that is set to "topmost"
is there a solution to this out the
Yes, there is.
Don't set the topmost flag on your forms.
There is no way to say "Stay on top of all forms, except ...".
Stay on top really means stay on top, if you don't want that, don't use it.
You may want to use .ShowDialog() instead of .Show() without TopMost. This will basically mean that new Forms created by your app will have to be closed if you would like to get to the bottom form (I guess that's why you use TopMost - to prevent doing stuff on forms that were opened before?)
my application opens n forms and the user can freely switch back and forth among these forms.
When the user decides to confirm the operations performed on one of the forms, I would like to block the other ones until this process (which can potentially open MessageBoxes and/or other forms) comes to an end.
It is not enough to disable the forms, since the user can't do anything on them, but the Activated event is fired, and this is exactly what I want to avoid.
I tried to set ControlStyles.Selectable to false to all these forms, but it doesn't work.
Just in order to make it clearer, the forms cover the whole screen, so the users activate them clicking on the taskbar. This is the situation where opening a modal form and having the confirm code executed there does not prevent the Activated event to be fired.
Try to use Form.ShowDialog() method.
You can use Form.ShowDialog Method method to display a modal dialog box in your application. When this method is called, the code following it is not executed until after the dialog box is closed.
