I have a wpf button like this:

<Button Click="button1_Click" Height="23" Margin="0,0,5,0" Name="button1" Width="75">Initiate</Button>

And I want to pass {Binding Code} passed as parameter to the button1_click handler.
How do I go about this?

Simple solution:

<Button Tag="{Binding Code}" ...>

In your handler, cast the sender object to Button and access the Tag property:

var myValue = ((Button)sender).Tag;

A more elegant solution would be to use the Command pattern of WPF: Create a Command for the functionality you want the button to perform, bind the Command to the Button's Command property and bind the CommandParameter to your value.
