where to put the "Code Behind C#" code?

Hi. I'm using Microsoft Expression Blend to work with the ArcGIS SDK for WPF, and I'm a bit new to both. I have been trying to integrate some of the interactive samples in the "ArcGIS API for Silverlight" section into my code, and I am a bit confused about where to put the code in the "Code Behind C#" tab of those samples.

More specifically, I know how to find the code-behind files for MainWindow and App (and my various user controls), but I'm not sure in which of those I should put the code-behind from the sample.

For example, this is the code-behind for the ElementLayer sample (

[INDENT]using System.Windows;
using System.Windows.Controls;

namespace ArcGISSilverlightSDK
[INDENT] public partial class ElementLayer : UserControl
[INDENT]  public ElementLayer()

  private void RedlandsButton_Click(object sender, RoutedEventArgs e)
   [INDENT]MessageBox.Show("You found Redlands");[/INDENT]

I've found through trial and error that I don't put all of that in MainWindow.xaml.cs. Rather, it seems that I need to include just the RedlandsButton_Click method to get things to work. But does that mean I can ignore the rest of the C# code, or do I need to put it elsewhere?

Any tips, or a point toward some relevant documentation, would be appreciated. Thanks much.
