Question

我有TabControl和1个TabPages并包含DataGridView。我使用代码：

从TabPages1创建TabPages2

    Dim Frm As New TabFormPage
    Dim MoreTabs As TabPage = Frm.TabPage1
    Dim i As Integer
    For i = 1 To TabControl1.TabPages.Count
        MoreTabs.Text = "TabPage" & i + 1
    Next i
    TabControl1.Controls.Add(MoreTabs)
    Frm.Dispose()

TabPages2控件与TabPages1相同

如果我在TabPages1中使用BackgroundWorker填充DataGridView，它就可以了。但是如果我在不同来源的每个新TabPages（例如TabPages2）中填充DataGridView，它就无法工作（TabPages2中的DataGridView /每个New TabPages都是空的/什么都没有）。它总是填充Tabpages1 DataGridView

如何使用相同的控件填充每个New TabPages中的每个DataGridView？这是我填写DataGridview的代码：

    Private Sub BackgroundWorker1_DoWork(sender As Object, e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
        MyConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FPathTab + ";Extended Properties=Excel 12.0;")
        MyCommand = New System.Data.OleDb.OleDbDataAdapter("select * from [" & CSheetTab1 & "]'", MyConnection)

        DtSet = New System.Data.DataSet
        DtSet.Clear()
        MyCommand.Fill(DtSet)
    End Sub
    Private Sub BackgroundWorker1_RunWorkerCompleted(sender As Object, e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted
        DataGridView1.DataSource = DtSet.Tables(0)
        dv = DtSet.Tables(0).DefaultView
        MaxRecords = DtSet.Tables(0).Rows.Count
        MyConnection.Close()
        DataGridView1.Columns("F20").Visible = False
        DataGridView1.Columns("F21").Visible = False
        DataGridView1.Columns("F22").Visible = False
    End Sub

感谢您的帮助
