Why not
public class BoundCellRendererText : CellRendererText
{
string fieldName;
public BoundCellRendererText(string _fieldName) : CellRendererText()
{
this.fieldName = _fieldName
}
public string FieldName { get { return this.fieldName; } }
}
And use that in place of CellRendererText.
BoundCellRendererText colr = new BoundCellRendererText(fieldname);
colr.Editable = true; //Make every single Cell editable
colr.Edited += CellEdit;
...
treeview.AppendColumn(col); //Add the Column to the Treeview
And then in the EditedHandler your "o" would be your
BoundCellRendererText that knows about the field name.
