          }

Answer 1

确保Windows应用程序中没有Gridview。有一个控件以行和列的形式显示数据，即DataGridView。这是从SQL Server数据库通过数据表绑定数据的最佳有用链接 。

Answer 2

尝试使用dataGridView2.DataSource = dt.DefaultView;

Answer 3

Sir, asp.net or windows? You need to add dataGridView2.DataBind(); after dataGridView2.DataSource=dt;

Hope, it helps.
