<Window x:Class="SmokeyBox2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        SizeToContent="WidthAndHeight" WindowStyle="None" AllowsTransparency="True"
        MouseLeftButtonDown="Window_MouseLeftButtonDown">
    <Border Background="#50FFFFFF" CornerRadius="5" BorderThickness="2,0,2,2"
            Padding="5 1 5 5">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"></RowDefinition>

            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"></ColumnDefinition>
                <ColumnDefinition Width="Auto"></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <Label Grid.Row="0" Grid.Column="0" Background="Transparent"  Content="SmokeyBox" 
                   MouseLeftButtonDown="Label_MouseLeftButtonDown" />
            <TextBox Grid.Row="1" Grid.Column="0" Name="searchText" Width="450" FontFamily="Arial" Foreground="DarkGray"
