You have error in two lines:

var selectionDisplay = new SelectionDisplay(button.Label as string, button.Tag as string);

and

var selectionDisplay = new SelectionDisplay(button.Label, button.Background); 

and you define the constructor as

public SelectionDisplay(string itemId)
    {
        this.InitializeComponent();

        this.messageTextBlock.Text = string.Format(CultureInfo.CurrentCulture,Properties.Resources.SelectedMessage,itemId);

    }

if you need to define with some default value then you need to do like this

public SelectionDisplay(string itemId, string nextParam="default value")
    {
        this.InitializeComponent();

        this.messageTextBlock.Text = string.Format(CultureInfo.CurrentCulture,Properties.Resources.SelectedMessage,itemId);

    }

In this case you can either pass next argument or ignore it
