使用 2 个文本框过滤绑定源

Question

我正在使用 Visual Studio 10，使用 Oracle 数据库在 VB 中编程。我需要使用 2 个变量对 DataGridView 进行筛选。到目前为止的代码如下所示：

TableBindingSource1.Filter = "[FIELD1] = '" & TextBox1.Text & "'"
DataGridView1.Refresh()

如何在此示例中插入 FIELD2 和 Textbox2，使两个过滤器一起工作？非常感谢。

可能是这样的：

Me.BindingSource.Filter = "FIELD1= '" & txt1.Text & "' AND FIELD2 >= " & txt2.Text

'例子

       ' Get a DataView of the table contained in the dataset.

  Dim tables As DataTableCollection = set1.Tables
  Dim view1 As New DataView(tables(0))

' Create a DataGridView control and add it to the form.

  Dim datagridview1 As New DataGridView()
  datagridview1.AutoGenerateColumns = True
  Me.Controls.Add(datagridview1)

' Create a BindingSource and set its DataSource property to
' the DataView.
  Dim source1 As New BindingSource()
  source1.DataSource = view1

' Set the data source for the DataGridView.
datagridview1.DataSource = source1

' The Filter string can include Boolean expressions.
source1.Filter = "artist = 'Dave Matthews' OR cd = 'Tigerlily'"
