I'm not sure how to ask this as I'm a newby at ADO.Net, so this is a bit long.

I created a DataTable with:

// Create a DB factory
DbProviderFactory oDataFactory = 
	DbProviderFactories.GetFactory(this._sProviderType);

// Get a connection object from the factory
DbConnection oConnection = oDataFactory.CreateConnection();
oConnection.ConnectionString = sConnectionString;

// Get a command object from the factory
DbCommand oCommand = oDataFactory.CreateCommand();
oCommand.CommandText = sQuery;
oCommand.Connection = oConnection;

// Get a data adapter from the factory
DbDataAdapter oDataAdapter = oDataFactory.CreateDataAdapter();
oDataAdapter.SelectCommand = oCommand;

// Create the data table and fill it
DataTable oDataTable = new DataTable(sCursorName);
oDataAdapter.Fill(oDataTable);

// Copy the table to the return variable
oRetVal = oDataTable;

This works really well with no problems. I have then bound the instance of the DataTable
to a DataGrid. Again, all is well so far.

Now that I can modify data, how do I send changes back to the data source. So far I have:

public bool UpdateData(DataTable oDataTable)
{
    // Declare variables
    bool bRetVal = true;

    // Create a dataset of changes
    DataTable oChanges = oDataTable.GetChanges(DataRowState.Modified);

    // If any rows exist in the changes cursor...
    if (oChanges.Rows.Count > 0)
    {

        // WHAT GOES HERE???
    }

    return bRetVal;
}
