vb中的datagridview不显示数据了！

Question

Public Class 图书信息查询

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Me.Hide()
    主窗口.Show()
End Sub

Private Sub 图书信息查询_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    'TODO:  这行代码将数据加载到表“DataSet1.图书”中。您可以根据需要移动或删除它。
    Me.图书TableAdapter.Fill(Me.DataSet1.图书)

Private Sub DataGridView1_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

End Sub

End Class

预览数据没有问题，但是就是显示不出数据。
