    "Confirm Delete",
    MessageBoxButton.YesNo,
    MessageBoxImage.Warning,
    MessageBoxResult.No);  // Default button

switch (result)
{
    case MessageBoxResult.Yes:

        break;
    case MessageBoxResult.No:
        // Cancelled

}

3. Custom Modal Dialog

3.1 Dialog Window XAML

<Window x:Class="MyApp.Dialogs.SettingsDialog"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Settings"
        Width="400" Height="300"
        WindowStartupLocation="CenterOwner"
        ResizeMode="NoResize"
        ShowInTaskbar="False">
    <Grid Margin="20">
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>

        <!-- Content -->
        <StackPanel Grid.Row="0">
            <Label Content="User Name:"/>
            <TextBox x:Name="UserNameTextBox" Margin="0,5,0,15"/>
            <CheckBox x:Name="EnableNotificationsCheckBox"
                      Content="Enable notifications"/>
        </StackPanel>

        <!-- Dialog buttons -->
        <StackPanel Grid.Row="1" Orientation="Horizontal" HorizontalAlignment="Right">
            <Button Content="OK" Width="80" Margin="0,0,10,0"
                    Click="OkButton_Click" IsDefault="True"/>
            <Button Content="Cancel" Width="80"
                    Click="CancelButton_Click" IsCancel="True"/>
        </StackPanel>
    </Grid>
</Window>
