需要的3个电话号码之一.Validator

Question

我正在尝试动态创建一个用于联系信息的表。我知道你输入你的名字，选择与客户的关系，然后填写3个电话号码。添加新行时，我正在制作它，以便至少填写其中一个数字。完成后，您可以添加新的联系人。

我在VB.Net中这样做，并希望有人能够提供帮助。

在查看代码之前，我想提一下我已经注释掉了很多行。仅仅为了代码背后的一些背景，我尝试了很多方法，并不确定我是否在正确的道路上。无论如何，这里是我进行动态验证的代码块。

        tCell = New TableCell
        tCell.CssClass = "dynamicTCell"
        tCell.Controls.Add(tDrop)
        tRow.Cells.Add(tCell)
        tCell.Controls.Add(conRowRequired)

        tBoxHome = New TextBox
        tBoxHome.ID = "con" + conRows.ToString + "HomePhone"
        'tBoxHome.ValidationGroup = "conPhoneNumbers" + conRows.ToString
        'tBoxHome.CausesValidation = True

        conRowRequiredHome = New RequiredFieldValidator
        'conRowRequiredHome = New CustomValidator
        'conRowRequiredHome.ClientValidationFunction = "ServerValidation"
        conRowRequiredHome.ID = "conHomePhoneRequired" + conRows.ToString
        'AddHandler conRowRequiredHome.ServerValidate, AddressOf ServerValidation

        'tBoxHome = conTable.FindControl("con" + conRows.ToString + "HomePhone")
        conRowRequiredHome.ControlToValidate = tBoxHome.ID
        'conRowRequiredHome.ValidationGroup = "conPhoneNumbers"
        conRowRequiredHome.Display = ValidatorDisplay.Dynamic
        conRowRequiredHome.ErrorMessage = "*"

        tCell = New TableCell
        tCell.CssClass = "dynamicTCell"
        tCell.Controls.Add(tBoxHome)
        tCell.Controls.Add(conRowRequiredHome)

        tRow.Cells.Add(tCell)
        'conRowRequiredHome.IsValid = False

        tBoxWork = New TextBox
        tBoxWork.ID = "con" + conRows.ToString + "WorkPhone"
        'tBoxWork.ValidationGroup = "conPhoneNumbers" + conRows.ToString
        'tBoxWork.CausesValidation = True

        'conRowRequiredWork = New CustomValidator
        conRowRequiredWork = New RequiredFieldValidator
        'conRowRequiredWork.ClientValidationFunction = "ServerValidation"
        conRowRequiredWork.ID = "conWorkPhoneRequired" + conRows.ToString
        'tBoxWork = conTable.FindControl("con" + conRows.ToString + "WorkPhone")
        conRowRequiredWork.ControlToValidate = tBoxWork.ID
        'conRowRequiredWork.ValidationGroup = "conPhoneNumbers"
        conRowRequiredWork.Display = ValidatorDisplay.Dynamic
        conRowRequiredWork.ErrorMessage = "*"

        tCell = New TableCell
        tCell.CssClass = "dynamicTCell"
        tCell.Controls.Add(tBoxWork)
        tRow.Cells.Add(tCell)
        'conRowRequiredWork.IsValid = False
        tCell.Controls.Add(conRowRequiredWork)

        tBoxCell = New TextBox
        tBoxCell.ID = "con" + conRows.ToString + "CellPhone"
        'tBoxCell.ValidationGroup = "conPhoneNumbers" + conRows.ToString
        ' tBoxCell.CausesValidation = True


        conRowRequiredCell = New RequiredFieldValidator
        'conRowRequiredCell = New CustomValidator
        'conRowRequiredCell.ClientValidationFunction = "ServerValidation"
        conRowRequiredCell.ID = "conCellPhoneRequired" + conRows.ToString
        'tBoxCell = conTable.FindControl("con" + conRows.ToString + "CellPhone")
        conRowRequiredCell.ControlToValidate = tBoxCell.ID
        'conRowRequiredCell.OnServerValidate = "ServerValidation"
        'conRowRequiredCell.ValidationGroup = "conPhoneNumbers"
        conRowRequiredCell.Display = ValidatorDisplay.Dynamic
        conRowRequiredCell.ErrorMessage = "*"


        tCell = New TableCell
        tCell.CssClass = "dynamicTextBoxBRRounded"
        tCell.Controls.Add(tBoxCell)
        tRow.Cells.Add(tCell)
        tCell.Controls.Add(conRowRequiredCell)

        'Dim flag As Boolean
        'If tBoxWork IsNot Nothing AndAlso tBoxCell IsNot Nothing AndAlso tBoxHome IsNot Nothing Then
        '    'If (tBoxHome.Text = "" And tBoxWork.Text = "" And tBoxCell.Text = "") Then
        '    'args.IsValid = False
        '    If (tBoxHome.Text <> "" OrElse tBoxCell.Text <> "" OrElse tBoxWork.Text <> "") Then
        '        flag = True
        '    End If
        'End If

我用于尝试conRoeRequiredCell.ClientValidationFunction =“ServerValidation”的函数如下所示。我知道它说Sub Class，但我也试过它作为一个功能，没有优势。

    'Protected Sub ServerValidation(ByVal source As Object, ByVal args As ServerValidateEventArgs)
'    args.IsValid = False

'    Dim conTable As Table = DirectCast(PlaceHolderSiblings.FindControl("conTable"), Table)

'    Dim tBoxWork As TextBox = conTable.FindControl("cony" + Session("conRows").ToString + "WorkPhone")
'    Dim tBoxCell As TextBox = conTable.FindControl("con" + Session("conRows").ToString + "CellPhone")
'    Dim tBoxHome As TextBox = conTable.FindControl("con" + Session("conRows").ToString + "HomePhone")

'    If tBoxWork IsNot Nothing AndAlso tBoxCell IsNot Nothing AndAlso tBoxHome IsNot Nothing Then
'        'If (tBoxHome.Text = "" And tBoxWork.Text = "" And tBoxCell.Text = "") Then
'        'args.IsValid = False
'        If (tBoxHome.Text <> "" OrElse tBoxCell.Text <> "" OrElse tBoxWork.Text <> "") Then
'            args.IsValid = True
'        End If
'    End If
'End Sub

如果这是草率的，请告诉我如何/如何解决它，我会。在Visual Basic和StackOverFlow中，我仍然是一个新手，看到这是我的第一篇文章。我希望我错过了一些有助于理解这一点的代码，所以任何问题都要求离开，我会尽快回复。
