Display Friendly Name in CheckedListBox

Question

I'm adding items from a List to a CheckedListBox. I want that box to display the friendly name of the item to the user but have a "secret" actual value to use when the user selects it.

foreach (string s in x)
{
    checkedlistBox1.Items.Add(friendlyValue);
    //Now how do I get this to have the real value?
}

With drop down menus I can set the DisplayName and ValueName to something and use something like:

combobox1.Items.Add(new ComboBoxItem { friendlyValue = x, realValue = y });

I can't seem to do this with a CheckedListBox.

Answer 1

Set the DisplayMember and ValueMember properties on the CheckedListBox.

Those are functionally equivalent to the DisplayName and ValueName properties of the ComboBox.

public class MyClass
{
    public string FriendlyValue { get; set; }
    public string RealValue { get; set; }
}

public class YourForm : Form
{
    public YourForm()
    {
        var friendlyList
            = new List<string>();  // imagine it's populated with friendly values

        foreach (var fv in friendlyList)
        {
            checkedListBox1.Items.Add(
                new MyClass { FriendlyValue = fv, RealValue = ??? });
        }

        checkedListBox1.DisplayMember = "FriendlyValue";
        checkedListBox1.ValueMember = "RealValue";        
    }
}
