You’ll need to create a Command (subclass of ICommand) and set your button command attribute to it.

You are using a click event, so i doubt the command parameter will be available when you handle the event.

if you are only interested in this UserId field and not other features of Command (like CanExecute etc), you can just use the Tag property of the button as you can get this via the code behind.

 <Button Height="23" Name="button1" Tag="{Binding Path=UserId }" Click="button1_Click" Width="75">Button</Button>

In your button1_click event you can just access

var UserID = ((Button)sender).Tag; //cast the actual button in the grid
