使用CheckBox过滤DataGridView

Question

单击Button1时，使用CheckBox的My Filter DataGridView不起作用。请给我解决方案。我在下面附上我的代码：

Public Class Form1

    Private Sub Table1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Table1BindingNavigatorSaveItem.Click
        Me.Validate()
        Me.Table1BindingSource.EndEdit()
        Me.TableAdapterManager.UpdateAll(Me.EmployeeTBDataSet)

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'EmployeeTBDataSet.Table1' table. You can move, or remove it, as needed.
        Me.Table1TableAdapter.Fill(Me.EmployeeTBDataSet.Table1)

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim query As String = ""
        Dim c1check As Boolean

        Dim myList As New List(Of String)
        For Each cb As CheckBox In GroupBox1.Controls.OfType(Of CheckBox)()
            ' we can know if checkbox in GroupBox1 is checked or not
            If CheckBox1.Checked Then
                c1check = True
                ' get the text of checkbox that checked by user
                myList.Add(cb.Text)
            End If
        Next

        If c1check Then
            ' if checkbox in groupbox1 is checked, we will create this query to our database
            query = "SELECT ID FROM Table1 WHERE Status='" & String.Join("' or Status=" + "'", myList) + "'"
        End If

    End Sub
End Class
