[Gtk-sharp-list] Query all values from TreeView

[David S]

Ok sorry jumped the gun on the reply lol here is what you would want

List<string> rowData = new List<string>();
mymodel.Foreach( (model, path, iter) => {
   string data = model.GetValue( iter, 0 ) as string; // could cut this out
... but whatever
   // manipulate data
   rowData.Add( data );
   return false; // a return value of true stops the foreach
} );
string allRows = rowData.Aggregate( (current,next) => current + next );
