绑定源过滤

Question

希望你能帮我这个忙。

我想datagridview通过使用诸如名称之类的特定关键字来过滤我的内容。我使用了一个数据集，然后将其绑定到数据源，然后再绑定到我datagridview的视图中。

当我使用时，bindingsource.filter我无法获得任何结果。

这是我的代码：

    Dim ds As New DataSet
    Dim bs As New BindingSource

    Dim sql As String = "SELECT TOP 10 * FROM dbo.DimCustomer"
    Dim connection As New SqlConnection(sqlconnectionstring)
    Dim dataadapter As New SqlDataAdapter(sql, connection)



    connection.Open()
    ds.Clear()
    dataadapter.Fill(ds, "Customer")
    connection.Close()


    bs.DataSource = ds

    dgv1.DataSource = bs
    dgv1.DataMember = "Customer"
    bs.Filter = "FirstName = 'Jon'"

谢谢大家的帮助，但是我可以通过以下代码使用它：

Dim sql As String = "select * from HumanResources.vEmployee"
Dim connection As New SqlConnection(sqlconnectionstring)
Dim dataadapter As New SqlDataAdapter(sql, connection)
Dim dsView As New DataView()

Try
  connection.Open()
  ds.Clear()
  dataadapter.Fill(ds, "test")
  dsView = ds.Tables(0).DefaultView
  bs.DataSource = dsView
  dgv1.DataSource = bs
  bs.Filter = "FirstName like 'J%'"
Catch ex As Exception
  MessageBox.Show("Error while connecting to SQL Server." & ex.Message)
Finally
  connection.Close()
End Try
