[ModernDialog][MessageBoxResult] Cancel Button on second win

Hi,

I'm using the ModernDialog that contains a UserControl, it has a custom button:

Button customButtonClose = new Button() { Content = "Close" };

customButtonClose.Click += (ss, ee) =>

{

CheckPendingChanges();

dialog.Close();

};

dialog.Buttons = new Button[] { customButtonSave, customButtonClose };

In CheckPendingChanges():

var rsltDialog = Utils.ShowMessageYesNoClose("Are there a pending changes, save?");

if (rsltDialog == MessageBoxResult.Yes)

{

result = customFunction();

}

where Utils.ShowMessageYesNoClose() is:

public static MessageBoxResult ShowMessageYesNoClose(string text)

{

var dlg = new ModernDialog

{

Title = (string)Application.Current.FindResource("mdAppTitle"),

Content = new BBCodeBlock { BBCode = text, Margin = new Thickness(0, 0, 0, 8) },

MinHeight = 0,

MinWidth = 0,

MaxHeight = 480,

MaxWidth = 640,

};

dlg.YesButton.Content = (string)Application.Current.FindResource("msgBoxResultYes");

dlg.NoButton.Content = (string)Application.Current.FindResource("msgBoxResultNo");

dlg.Buttons = new[] { dlg.YesButton, dlg.NoButton, customCancelClose, dlg.CancelButton };

dlg.ShowDialog();

return dlg.MessageBoxResult;

}

I have this problem: when I click on CancelButton, the two windows are closing together, but I would close only second window, the one with the application.

Where is the error?
