One click handler for multiple buttons in stackpanel - class

Question

I have following xaml:
<GroupBox x:Name="GroupBoxInworp" IsEnabled="True" Header="Inworp" HorizontalAlignment="Stretch" Margin="10,120,10,0" VerticalAlignment="Top" VerticalContentAlignment="Stretch">
<StackPanel x:Name="StackPanelInworp" Button.Click="button_Click">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0">
<Button x:Name="btnTweeEuro" Margin="10" MinWidth="220" Content="2" Click="btnTweeEuro_Click"></Button>
<Button x:Name="btnEenEuro" Margin="10" MinWidth="220" Content="1" Click="btnEenEuro_Click"></Button>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0">
<Button x:Name="btnVijftigEurocent" Margin="10" MinWidth="100" Content="50" Click="btnVijftigEurocent_Click"></Button>
<Button x:Name="btnTwintigEurocent" Margin="10" MinWidth="100" Content="20" Click="btnTwintigEurocent_Click"></Button>
<Button x:Name="btnTienEurocent" Margin="10" MinWidth="100" Content="10" Click="btnTienEurocent_Click"></Button>
<Button x:Name="btnVijfEurocent" Margin="10" MinWidth="100" Content="5" Click="btnVijfEurocent_Click"></Button>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5">
<Label Content="Huidige inworp:" MinWidth="160"></Label>
<Label x:Name="lblHuidigeInworp" Content="" MinWidth="300" HorizontalContentAlignment="Right"></Label>
</StackPanel>
</StackPanel>
</GroupBox>
I have following code:
private void GeldClick(decimal Inworp)
{
TotaalInworp += Inworp;
lblHuidigeInworp.Content = String.Format("€ {0}", TotaalInworp);
}
private void btnTweeEuro_Click(object sender, RoutedEventArgs e)
{
GeldClick(2.00M);
}
private void btnEenEuro_Click(object sender, RoutedEventArgs e)
{
GeldClick(1.00M);
}
private void btnVijftigEurocent_Click(object sender, RoutedEventArgs e)
{
GeldClick(0.50M);
}
private void btnTwintigEurocent_Click(object sender, RoutedEventArgs e)
{
GeldClick(0.20M);
}
private void btnTienEurocent_Click(object sender, RoutedEventArgs e)
{
GeldClick(0.10M);
}
private void btnVijfEurocent_Click(object sender, RoutedEventArgs e)
{
GeldClick(0.05M);
}
I want to create one handler for all click events with a for or a switch.
The handler would be like
StackPanelInworp.AddHandler(Button.ClickEvent, new RoutedEventHandler(button_Click));
I also want to create a class, in which i can place the event handler with the for or switch. There are 6 buttons.
How can this be accomplished? Also, it concerns decimals so a switch would be impossible i think?

I came up with this:
Xaml
<StackPanel x:Name="StackPanelInworp">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0">
<Button x:Name="btnTweeEuro" Margin="10" MinWidth="220" Content="2" Click="btnGeld_Click"></Button>
<Button x:Name="btnEenEuro" Margin="10" MinWidth="220" Content="1" Click="btnGeld_Click"></Button>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0">
<Button x:Name="btnVijftigEurocent" Margin="10" MinWidth="100" Content="50" Click="btnGeld_Click"></Button>
<Button x:Name="btnTwintigEurocent" Margin="10" MinWidth="100" Content="20" Click="btnGeld_Click"></Button>
<Button x:Name="btnTienEurocent" Margin="10" MinWidth="100" Content="10" Click="btnGeld_Click"></Button>
<Button x:Name="btnVijfEurocent" Margin="10" MinWidth="100" Content="5" Click="btnGeld_Click"></Button>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5">
<Label Content="Huidige inworp:" MinWidth="160"></Label>
<Label x:Name="lblHuidigeInworp" Content="" MinWidth="300" HorizontalContentAlignment="Right"></Label>
</StackPanel>
</StackPanel>
Code:
//Methode voor uitvoeren van alle click events mbt Geld
private void GeldClick(decimal Inworp)
{
TotaalInworp += Inworp;
lblHuidigeInworp.Content = String.Format("€ {0}", TotaalInworp);
}
//Enkel click event voor alle knoppen mbt Drank
private void btnGeld_Click(object sender, EventArgs e)
{
Button btn = sender as Button;
switch (btn.Content.ToString())
{
case "2":
GeldClick(2.00M);
break;
case "1":
GeldClick(1.00M);
break;
case "50":
GeldClick(0.50M);
break;
case "20":
GeldClick(0.20M);
break;
case "10":
GeldClick(0.10M);
break;
case "5":
GeldClick(0.05M);
break;
}
}
Anyone knows improvements? Wanted to work with the stackpanelname for the buttons but don't know how to ...
