我建立了一个datagrid，取了名字叫dg1，写了代码，跑了程序不显示是怎么回事，用的ODBC连接的数据库，求大佬帮忙
private void DataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
string sql = "select* from s;";
string constructorString = "Dsn=学生信息;uid=root";
using (OdbcConnection conn = new OdbcConnection(constructorString))
{
OdbcDataAdapter oda = new OdbcDataAdapter(sql, conn);
DataSet ds = new DataSet();
oda.Fill(ds);
dg1.ItemsSource = ds.Tables[0].DefaultView;
}
}
是不是我哪里少了什么东西？？？
