Not a question. Help with what? Why do you think you need to add a row to a data-bound grid view? what to do with that row?

The error means exactly what is says. You are trying to add a new row to a databound grid. Either remove the binding or add the object to your database and re-query the data.

Yes and? YOU CAN"T DO THAT! How many times do you have to be told? Either remove the binding or add the object to your database and re-query the data.

Dont you just need to add a new object to the DataGrid DataSource

Person Bob = new Person();
//Assumption PersonList is DataSource to DataGrid
PersonsList.Add(Bob);
