C# database application

Hi I'm working on a c# windows mdi application. But I'm stuck. I've created a datagrid filled with a dataset as its datasource. The datagrid has full row select and a contextmenu with the add/edit/delete options for each row. To add/edit a row I use a seperate form. I have some trouble updating this datagrid, can anyone please help me. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
