C# - Display Dictionary In ListBox?

I've got a little problem with displaying my Dictionary in ListBox.

public static Dictionary<String, List<String>> MyDict = new Dictionary<string,
List<String>>();
...
if(MyDict[value1] == null){
List<String> Temp_List = new List<String>();
Temp_List.Items.Add(sth);
MyDict[value1] = Temp_List;
}
else if(MyDict[value1].Count < 4){
List<String> Temp_List = new List<String>();
Temp_List = MyDict[value1];
Temp_List.Add(sth);
MyDict[value1] = Temp_List;
}

and I'd like to display in Page_Load (after logging) a ListBox which will have List from MyDict for this login. Eg.
Login is : sally
And list contains of: she, no, then
And after sally logging I'd like to see result like this:

she
no
then

and I cannot use BindingSource
