tbh I think i have done something I shouldnt have done as Im a noob and it
appears to work.

1) I dropped a binding source on my form, then dropped a bindingnavigator
and linked the two together in the property editor.
private System.Windows.Forms.BindingSource _dataSource;
private System.Windows.Forms.BindingNavigator Navigator;

2) I created my StringResource class
internal class StringResource
{
private string _stringID = "";
private string _englishOriginal = "";
private string _translation = "";
public string StringID
{
get { return _stringID; }
set { _stringID = value; }
}
public string EnglishOriginal
{
get {return _englishOriginal;}
set{_englishOriginal = value;}
}
public string Translation
{
get { return _translation; }
set { _translation = value; }
}
}

3) I dropped a datagridview on the form and manually created 3 columns. I
then typed in DataPropertyName to link those to the associated properties of
the StringResource class.The following text is what vis studio autogenerated
for my "StringID" datagridview column. I set datagridview.DataSource
property in the designer to my BindingSource

this.ResourceID.DataPropertyName = "StringID";
this.ResourceID.HeaderText = "Resource ID";
this.ResourceID.Name = "ResourceID";
this.ResourceID.ReadOnly = true;
this.ResourceID.SortMode =
System.Windows.Forms.DataGridViewColumnSortMode.Automatic;

4) At run time I added new StringResource objects to the BindingSource as
follows
_dataSource.Clear();
foreach(blah blah)
{
StringResource res = new StringResource((string)de.Key, (string)de.Value);
_dataSource.Add(res);
}

So.... _dataSource.DataSource is (none)
Ive not generated any other objects eg DataView, DataTable etc etc
