Hi,
I would suggest to create a UserControl that shows the dialog with the title, message and buttons. The user control will have a transparent/semitransparent background panel that will avoid clicking the controls below.
<UserControl
xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
x:Class="MessageBoxControl">
<Grid Background="#40000000">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25*"/>
<ColumnDefinition Width="50*"/>
<ColumnDefinition Width="25*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="25*"/>
<RowDefinition Height="50*"/>
<RowDefinition Height="25*"/>
</Grid.RowDefinitions>
<Border x:Name="dialog" Grid.Column="1" Grid.Column="1" ...>
... message dialog here
</Border>
</Grid>
</UserControl>
To show the dialog you will add the user control to a container that covers the entire screen and that is on top of any other control.
<Grid
xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005">
<Grid x:Name="LayoutRoot">
... normal controls placed here
</Grid>
<Grid x:Name="MessageBoxContainer">
... message boxes added here
</Grid>
</Grid>

Please, paste the XAML and CS here to investigate what is happening.
Thanks!

and this is how i'm using the MessageBox
var gui = GetComponent<NoesisGUIPanel>();
Grid root = (Grid)gui.GetContent();
mainWindowRoot = (Grid)root.FindName("xpGrid");
MessageBox msgBox = new MessageBox
{
Title = "Quit?",
Message = "Do you really want to quit?",
OkText = "Yes!",
CancelText = "Cancel",
};
mainWindowRoot.Children.Add(msgBox);

The problem is that the name given in the XAML and the one used in FindName does not match.
<Grid x:Name="LayoutRoot" Background="#80000000">
mainWindowRoot = (Grid)root.FindName("xpGrid");
It should be
mainWindowRoot = (Grid)root.FindName("LayoutRoot");
