当我关闭WPF中的主窗口时Excel关闭

Question

I have a Excel AddIn project which parses excel workbook and pops a wpf window from excel ribbon when clicked on a button. the problem is that when I close the window (UI control of type window)pop up. closing action on Window closes the Excel too.

the code is something like this to show the window.

MainWindow main= new MainWindow();
main.ShowDialog();

can someone tell what's wrong here?

Answer 1

I have to question why you are creating a new instance of MainWindow?

What you should be doing is ( http://msdn.microsoft.com/en-us/library/system.windows.window.showdialog.aspx ):

// Instantiate window
DialogBox dialogBox = new DialogBox();

// Show window modally 
// NOTE: Returns only when window is closed
Nullable<bool> dialogResult = dialogBox.ShowDialog();
