LIstbox Selected Item content to textblock

I am sure there is a simple solution to this, but I can't seem to find it at the moment.

I am trying to disaply the content of the selection listbox in a textblock as text using the below code.

private void SelectionToText(object sender, EventArgs e)
{
    ListBoxItem selection = (ListBoxItem)TextListBox.SelectedItem;

    selectionText.Text = "This is the " + selection;

}

For some reason the textblock just displays

"This is the System.Windows.Controls.ListBoxItem "

I initial thought it was because I hasn't converted to a string, but that didn't work either.

Any suggestions?

Or you can do it without code behind, in silverlight, by binding the text property of the textblock to the selecteditem.content property of the listbox.

<TextBlock Text="{Binding SelectedItem.Content, ElementName=list}"/>

Where list is the name of my ListBox.

Please write as this:

private void SelectionToText(object sender, EventArgs e)
{
    MyListBoxItem selection = (MyListBoxItem)TextListBox.SelectedItem;

    selectionText.Text = "This is the " + selection.Content.ToString();

}

You can reference the Content property of the ListBoxItem

selectionText.Text= "This is the " + selection.Content.ToString();

If I am not wrong, you need to do the following code

Convert.ToString(TextListBox.SelectedItem);

This will return the value of SelectedItem

You can create a custom class

public class MyListBoxItem
{
    public MyListBoxItem(string value, string text)
    {
        Value = value;
        Text = text;
    }

    public string Value { get; set; }
    public string Text { get; set; }

    public override string ToString()
    {
        return Text;
    }
}

Add items to your ListBox like:

listBox1.Items.Add(new MyListBoxItem("1", "Text"));

And this will work

private void SelectionToText(object sender, EventArgs e)
{
    MyListBoxItem selection = (MyListBoxItem)TextListBox.SelectedItem;

    selectionText.Text = "This is the " + selection;

}
