MessageDialog Style

[estradege]

Hi everyone,
I would like to use the ShowMessageAsync function to display a confirmation for delete an item. The window is a small popup and the MessageDialog is not completely display :

Is there a way to style the message dialog window and reduce the padding ?

I tried to add a ResourceDictionary but it doesn't work:

App.xaml :

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml" />
            <ResourceDictionary Source="/Styles/MessageDialog.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

MessageDialog.xaml :

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:Dialogs="clr-namespace:MahApps.Metro.Controls.Dialogs;assembly=MahApps.Metro">
    <Style x:Key="CustomMessageDialog"
        BasedOn="{StaticResource {x:Type Dialogs:BaseMetroDialog}}"
        TargetType="{x:Type Dialogs:MessageDialog}">
        <Setter Property="Background" Value="Red"></Setter>
        <Setter Property="Opacity" Value=".2"></Setter>
        <Setter Property="Margin" Value="0"></Setter>
        <Setter Property="Padding" Value="0"></Setter>
    </Style>
</ResourceDictionary>

Thanks for your help,

I think you can just set these properties:

MahApps.Metro/src/MahApps.Metro/Themes/Dialogs/MessageDialog.xaml

Lines 23 to 27 in 509c9d7

	<Grid.ColumnDefinitions>
	<ColumnDefinition Width="{TemplateBinding DialogContentMargin}" />
	<ColumnDefinition Width="{TemplateBinding DialogContentWidth}" />
	<ColumnDefinition Width="{TemplateBinding DialogContentMargin}" />
	</Grid.ColumnDefinitions>

Thanks,
how can I set the DialogContentMargin property? The MessageDialog is open via the function ShowMessageAsync of MetroWindow class.
