歌颂祖国的朗诵词:.net中datagrid的问题

.net的winform格式的datagrid是没有办法设定最后一行是否可见的。但是，可以通过设定dataview的AllowNew属性来去除消息最后空白行。例如：
string connString = @"Provider=Microsoft.JET.OLEDB.4.0;data source=C:\northwind.mdb";

string sqlString = "SELECT * FROM customers";

// Connection object

OleDbConnection connection = new OleDbConnection(connString);

// Create data adapter object

OleDbDataAdapter dataAdapter = new OleDbDataAdapter(sqlString, connection);

// Create a dataset object and fill with data using data adapter's Fill method

DataSet dataSet = new DataSet();

dataAdapter.Fill(dataSet, "customers");

// Attach dataset's DefaultView to the datagrid control

dataGrid1.DataSource = dataSet.Tables["customers"];

//no adding of new rows thru dataview...

CurrencyManager cm = (CurrencyManager)this.BindingContext[dataGrid1.DataSource, dataGrid1.DataMember];

((DataView)cm.List).AllowNew = false;
