Windows Forms datagrid do have internal DataGridRows property and get_DataGridRows method is the get accessor for this property. It's recomended to retrieve property value by obtaining a PropertyInfo object first and calling GetValue method on that object. Best regards, ----------- Igor Sukhovhttp://sukhov.net

I saw many problems with that implementation. In VS2005 they exposed the "OwnerDraw" of the ListView control so it is relatively simple to do your own.

Searching for DataGrid ComboBox[^] gives several results. I think one of those should match your needs.

Yes satish, Dataset has this kind of build in methods. Am looking at similar methods for custom classes. Well one alternative is using of XMLSerialization as disussed before Regards Kais
