C# Can I display an Attribute of an Object in a Dictionary as ListControl.DisplayMember?

Question

The aim is to see the list as a list of 'name's.

Here's the dictionary:

class Scripts
    {
        public Dictionary<int, Script> scripts = new Dictionary<int, Script>();
        ...
    }

Here's the attribute 'name' I'm after:

class Script
    {
        public string name { get; set; }
        ...
    }

And here's the problem:

public partial class MainForm : Form
{
    Scripts allScripts;

    public MainForm()
    {
        InitializeComponent();
        allScripts = new Scripts();
        setupDataSources();
    }

    private void setupDataSources()
    {
        BindingSource ketchup = new BindingSource(allScripts.scripts, null);
        //THIS LINE:
        listBoxScripts.DisplayMember = allScripts.scripts["Key"].name.ToString();
        listBoxScripts.ValueMember = "Key";
        listBoxScripts.DataSource = ketchup;
    }
    ...
}

I just can't think how to make that line work! Your advice is much appreciated!

Thanks

You can binding to Value and override ToString method in Script class.

private void setupDataSources()
{            
    BindingSource ketchup = new BindingSource(allScripts.scripts, null);
    listBoxScripts.DisplayMember = "Value";
    listBoxScripts.ValueMember = "Key";
    listBoxScripts.DataSource = ketchup;            
}

Script class:

class Script
{
    public string name { get; set; }

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