将数据粘贴到DataGridView vb.net

Question

所以今天早上我碰到了一堵墙：

使用此代码，我粘贴数据时会随机获得另一行显示。

它旨在接收1到99999之间的值

所以当我复制此内容时：

然后将其粘贴到程序中

下面是我的解决方案。您必须从事件中调用函数。在我的应用程序中，我需要决定是否允许PasteUnboundRecords子项粘贴，该子项由Allowed boolen

控制

Public Sub CopyRows(MyDataGridView As DataGridView)
    Dim d As DataObject = MyDataGridview.GetClipboardContent()
    Try
        Clipboard.SetDataObject(d)
    Catch
        MessageBox.Show("Text not copied, null value")
    End Try
End Sub

Sub PasteUnboundRecords(MyDataGridView As DataGridView)
    Dim Allowed As Boolean      
    Dim OriginLines As String() = Clipboard.GetText(TextDataFormat.Text).Split(New String(0) {vbCr & vbLf}, StringSplitOptions.None)
    Dim Xo As Integer = SelectedAreaMinColumn(MyDataGridview)
    Dim Yo As Integer = SelectedAreaMinRow(MyDataGridview)
    Dim X As Integer
    Dim Y As Integer
    Dim i As Integer
    Dim j As Integer
    Dim ii As Integer
    Dim jj As Integer = 0
    Dim m1 As Integer
    Dim n1 As Integer = OriginLines.Length  
    Dim m2 As Integer = SelectedAreaColumns(MyDataGridView)
    Dim n2 As Integer = SelectedAreaRows(MyDataGridview)
    Dim m2Max As Integer = MyDataGridview.Columns.Count
    Dim n2Max As Integer = MyDataGridview.Rows.Count

    For j = 0 To Math.Max(n1-1, n2-1)
        Y = Yo + j
        If Y = n2Max Then Exit For
        If j-jj*n1 = n1 Then jj = jj+1
        Dim OriginValue As String() = OriginLines(j-jj*n1).Split(New String(0) {vbTab}, StringSplitOptions.None)
        m1 = OriginValue.Length
        ii = 0
        For i = 0 To Math.Max(m1-1, m2-1)
            X = Xo + i
            If X = m2Max Then Exit For
            If i-ii*m1 = m1 Then ii = ii+1
            If X > 0 Then 'Avoid pasting in first column containing codes
                If Y = 0 Then 'Avoid first line
                    Allowed = True
                Else 'Check DataValidatios
                    If DataValidations(OriginValue(i-ii*m1), X) = "OK" Then
                        Allowed = True
                    Else
                        Allowed = False
                    End If

                If MyDataGridview.Rows(Y).Cells(X).ReadOnly Then
                    Allowed = False
