Datagridview未显示表中的所有记录

Question

你好我的datagridvw显示表中的所有记录减1。所以我的表有11行，而我的datagridvw显示10. 10是限制吗？

我使用VB 2010作为一个工作项目。我绑定了列：PartNbr，Qty（数量）和Price。我还有另外两列，但我希望它们隐藏起来。这是代码。希望你能帮助天才

Dim cmd As OleDbCommand = New OleDbCommand("SELECT PartNbr, Qty, Price FROM CompBOM  WHERE HeaderCounter LIKE '" & frmHeader.txtAutoNumber.Text & "' AND LabelName LIKE '" & mbLabel & "'", conn)
    adapter = New OleDbDataAdapter(cmd)

    'automatically generates Delete Update Insert Commands for dataadapter object
    Dim builder As OleDbCommandBuilder = New OleDbCommandBuilder(adapter)
    Me.DGView.DataSource = Me.bindingSource
    dataSet = New DataSet()
    adapter.Fill(dataSet, "CompBOMTable")
    DGView.DataSource = dataSet.Tables("CompBOMTable").DefaultView
    conn.Close()

End Sub

还有太多其他代码要包含这个就足够了
