Question

I’ve a simple code, here I add a row to my a datatable which is in my dataset:

 DigiLocalDataSet dataset = new DigiLocalDataSet();

 DataRow newClientsRow = dataset.Tables["clients"].NewRow();

 newClientsRow ["clientnr"] = "123";
 newClientsRow ["name"] = "Pascal";
 newClientsRow ["city"] = "London";

 dataset.Tables["clients"].Rows.Add(newClientRow);

 clientsTableAdapter.Fill(dataset.clients);

 this.DataContext = dataset.clients.DefaultView;

But I don’t see the inserted row in my datagrid, I see only the existing rows of the ‘clients’ table.

What’s wrong?

Answer 1

Your call to TableAdapter.Fill is filling your ‘clients’ DataTable with data retrieved from your data source, so you’re losing the record you manually added to the DataTable.
