How do I invoke a modal window from a wpf page? Window.showDialog() makes the window modal when it is invoked from a parent Window, however when invoked from a Page, the modal behaviour disappears. I tried using a PopUp control, but it doesnt appear to be as customizable as a window.
I am not sure how are you calling the window, but calling new Window().ShowDialog() from within a page inside frame, makes the new window modal to the whole application.

As my form includes many actions I want to call a popup window to do some actions.
But after the submission of the popup window. I have to replace a div in parent window.
1)How can I call a popup window which is modal?
2)How can the parent window know the child window is closed? (so that I can replace the div with new data)
Please help me...
You can use the jquery modal window shown in this link
While using the modal window in the link you can see that there is an event function called beforeClose. In this event, you can use callback function to update the div in the parent window.
I have a main window in Which I have a button. When i click that button i want to show a dialog box which i have made using a page. I am using
Page1 P = new Page(); //Page which i want to show over my main window
this.P.Visibility = Visibility.Visible;
when i used Window to make dialog box it is working fine but with pages there is no Show property associated. Does anyone know Of any method to display page over Mainwindow.
A Page cannot be shown as a window. For this you need to use Window, both can host the same XAML content, you just need to use the right container!
See this question:
Page vs Window in WPF?
New Thought, Maybe I am looking at this totally incorrectly. So Here is exactly what I am trying to do in case there is another option I am not aware of.
I have a WPF app, the main window shows a smaller dialog window using ShowDialog(), when a user clicks on the parent window that showed the dialog, I need to make the dialog window, flash, shake or blink.
AresAvatar posted a link that looks like it might be able to use, but is there another option I am not aware of?
My original Question.
Mouse click event when Modal window's parent is clicked in WPF app?
I have a wpf app that shows a modal window using ShowDialog().
I would like to fire an event when the user tries to click the parent window that is now disabled.
Is it possible on the parent to receive a click event when it has shown a modal window?
When I attempted this using an interaction trigger, the events never fired on parent window.
Otherwise, what suggestions / options are there.
Thanks
No WPF events are sent under these conditions. The only Windows message I can see that gets sent is WM_WINDOWPOSCHANGING. You could check for that message, and check if the window was disabled when it occurred. Here's a good article on checking WM_WINDOWPOSCHANGING.
Edit: that link seems to be dead. Here's an example on StackOverflow of checking window messages.
I know this is an old question but I'll post my solution in case any one needs it.
Set the dialog.owner prior to calling ShowDialog().
var dialog = new DialogWindow();
dialog.owner = MainWindow;
dialog.ShowDialog();
The result is that clicking on the main window, brings the dialog window to the front and makes the dialog window flash.
Suppose multiple Modal Windows shown above each other.
All of those have ShowInTaskbar = false, which means that in the TaskBar you only see the MainForm and all Modal Windows are hidden.
Now you press ALT+ TAB and the most upper modal Windows disappears. But you cannot get it back in front.
How should be this done correctly in your opinion?
If a modal window is getting stuck behind the main form, it sounds like you are not setting its owner. When you call showDialog(), you need to pass in the main form like this:
modalWin.showDialog(mainForm);
Any time you call showDialog(), and your program has another form that should be underneath, it is best to pass it as the owner. If you show modal window when there is already a modal window up, then pass the first modal window as the owner.
OK Just to complete it:
This is how to set an Owner to be a Winform for a Winform:
form.ShowDialog(ownerInstance);
This is how to set an Owner to be a Winform for a WPF Window:
MyWpfDialog dialog = new MyWpfDialog();
new System.Windows.Interop.WindowInteropHelper(dialog).Owner = ownerInstance.Handle;
dialog.ShowDialog();
This is how to set an Ownder to be a Wpf Window for a Wpf Window:
.Owner = Window.GetWindow(ownerInstance)
I have a WPF-window, in this you can click a button to see a new window. Now I want to disable, that you can click the main-window. It should be like a MessageBox.
You want to use dialog.ShowDialog().
Modeless dialogs (via dialog.Show) are ones that you can interact with the background window. Modal dialogs (via dialog.ShowDialog() are ones that don't allow you to interact with the parent window.
You're looking for Window.ShowDialog()
Try this:
dialogYouNeedToShow.Owner = App.Current.MainWindow;
dialogYouNeedToShow.ShowDialog();
ShowDialog will always show your dialog as a modal one, so you won't have access to background form.
Do you mean
MessageBox.Show()
or
myWindowName.ShowDialog()
?
