Question

这是我的代码，只接受文本框中的数字：

Select Case e.KeyChar
        Case "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", ".", vbBack
            e.Handled = False
        Case Else
            e.Handled = True
End Select

我还可以在datagridview的单元格中使用这些代码吗？还有如何限制no。单元格中的字符会自动显示，这意味着没有msgbox可以提示用户。

谢谢。

您可以在datagridview的编辑控件上尝试这段编码

Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
Try

    If 'Set the column/cell

         AddHandler e.Control.KeyPress, AddressOf TextNumberKeypress

    End If

Catch ex As Exception
    '... 
End Try

End Sub

   Sub TextNumberKeypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
   'Put the validations for your cell
    End Sub
