Trying to add two states to a button, first click opens a canvas, the second closes the canvas.
<ToggleButton x:Name="retailButton" Content="Button" Canvas.Left="203" Canvas.Top="107" Width="327" Height="83" RenderTransformOrigin="0.49,0.398" Visibility="Visible" Opacity="0" Click="retailButton_Click" IsEnabled="True" >
not sure about the code behind?
