Question

我正在编写一个VBA代码，该代码通过一系列单元格检查每个单元格是否有数据验证（下拉菜单），如果没有从另一个工作表的列表中为其分配一个。

我目前在检查当前单元格是否已经有数据验证的行上遇到问题。我得到错误1004“没有找到细胞”。

Sub datavalidation()

    Dim nlp As Range
    Dim lrds As Long
    Dim wp As Double
    Dim ddrange As Range

    Sheets("DataSheet").Select

        lrds = ActiveSheet.Range("A1").Offset(ActiveSheet.rows.Count - 1, 0).End(xlUp).Row

        Set nlp = Range("I3:I" & lrds)

        For Each cell In nlp

    'error on following line

            If cell.SpecialCells(xlCellTypeSameValidation).Cells.Count < 1 Then
                wp = cell.Offset(0, -8).Value

                Set ddrange = ddrangefunc(wp)

            End If

        Next

End Sub

有什么想法吗？谢谢

Answer 1

我知道这个问题已经过时了，但是当谷歌搜索＆＃34; excel vba检查单元格是否已经验证时，它会出现＃34;我想我会添加我的盐。

如果您呼叫Range的{{1}}对象仅代表一个单元格，则会扫描整个工作表以查找匹配项。如果您的数据量非常大，以前答案中提供的方法可能会变得有点慢。

因此，这是检查单个单元格是否有验证的更有效方法：

SpecialCells

Answer 2

Dim cell As Range, v As Long

For Each cell In Selection.Cells
    v = 0
    On Error Resume Next
    v = cell.SpecialCells(xlCellTypeSameValidation).Count
    On Error GoTo 0

    If v = 0 Then
        Debug.Print "No validation"
    Else
        Debug.Print "Has validation"
    End If
Next

Answer 3

如果您只想测试activecell，那么：

Sub dural()
    Dim r As Range
    On Error GoTo noval
    Set r = Cells.SpecialCells(xlCellTypeAllValidation)
    If Intersect(r, ActiveCell) Is Nothing Then GoTo noval
    MsgBox "Active cell has validation."
    Exit Sub
noval:
    MsgBox "Active cell has no validation."
    On Error GoTo 0
End Sub

Answer 4

另外，如果您想获得验证Source，可以使用以下内容...

Dim cell as Range
Dim rng as Range
Set rng = Range("A1:A10") 'enter your range

On Error Resume Next 'will skip over the cells with no validation

For Each cell In rng
    msgbox cell.Validation.Formula1
Next cell

Answer 5

这对我有用

Sub test()
    On Error Resume Next
        If ActiveCell.SpecialCells(xlCellTypeSameValidation).Cells.Count < 1 Then
            MsgBox "validation"
        Else
            MsgBox "no Validation"
        End If
    On Error GoTo 0
End Sub

大约4年后，我也在寻找细胞验证。结合这里的答案，这就是我提出的：

Option Explicit

Public Sub ShowValidationInfo()

    Dim rngCell             As Range
    Dim lngValidation       As Long

    For Each rngCell In ActiveSheet.UsedRange

        lngValidation = 0

        On Error Resume Next
        lngValidation = rngCell.SpecialCells(xlCellTypeSameValidation).Count
        On Error GoTo 0

        If lngValidation <> 0 Then
            Debug.Print rngCell.Address
            Debug.Print rngCell.Validation.Formula1
            Debug.Print rngCell.Validation.InCellDropdown
        End If
    Next

End Sub

Answer 7

寻找一种避免这种情况的方法，避免错误再次出现，这就是我的实现方式：

Option Explicit
' https://stackoverflow.com/questions/18642930/determine-if-cell-contains-data-validation
' Use this if you want to omit doing something to the cell added: http://dailydoseofexcel.com/archives/2007/08/17/two-new-range-functions-union-and-subtract/
Sub ValidationCells()

    Dim theSheet As Worksheet
    Dim lastCell As Range
    Dim validationRange As Range
    Dim validationCell As Range

    Application.EnableEvents = False ' optional

    Set theSheet = ThisWorkbook.Worksheets(1)

    theSheet.Unprotect ' optional

    ' Add a cell with a value and some validation to bypass specialcells error
    Set lastCell = theSheet.Cells(1, theSheet.Cells.Columns.Count)
    With lastCell
        .Value2 = 1
        .Validation.Add xlValidateWholeNumber, xlValidAlertInformation, xlEqual, "1"
    End With

    ' If usedrange is greater than 1 (as we added a single cell previously)
    If theSheet.UsedRange.Rows.Count > 1 Or theSheet.UsedRange.Columns.Count > 1 Then

        Set validationRange = theSheet.UsedRange.SpecialCells(xlCellTypeAllValidation)

        MsgBox validationRange.Address

        For Each validationCell In validationRange
            If validationCell.Address <> lastCell.Address Then
                MsgBox validationCell.Address
            End If
        Next validationCell

    End If

    lastCell.Clear

    Set validationRange = Nothing
    Set lastCell = Nothing

    theSheet.Protect ' optional

    Application.EnableEvents = True ' optional


End Sub

Answer 8

HasValidation=(not rCell.SpecialCells(xlCellTypeSameValidation) 什么都不是

确定单元格是否包含数据验证
