Parin likes using the diagonal border on some cells to show the value as "crossed out." She would like to use diagonal borders in a conditional format, however. When she tries, she can set other types of borders, but not a diagonal border—it is not selectable in the conditional format. She wonders if there is a way to use diagonal borders with conditional formats.
There is no direct way to do this when setting up a conditional format—Excel simply won't allow you to use diagonal borders with a conditional format. That means that you may want to look for and use an acceptable workaround. Here are a few ideas for the conditional format:
If you actually want to use the diagonal borders, then the only way to do it is to apply an explicit format to the cell and not rely on a conditional format. This can be done through the use of a macro, such as the following:
Private Sub Worksheet_Change(ByVal Target As Range) Dim c As Variant Dim addr As String Set Target = Range("C12:C20") If Intersect(Target, ActiveCell) Is Nothing Then Exit Sub For Each c In Target If c = 0 And Len(c) <> 0 Then addr = c.Address With Range(addr).Borders(xlDiagonalUp) .LineStyle = xlContinuous End With ElseIf c > 0 And Len(c) > 0 Then addr = ActiveCell.Address With Range(addr).Borders(xlDiagonalUp) .LineStyle = xlNone End With End If Next End Sub
You should right-click on a worksheet tab, display the code window from the resulting Context menu, and then paste this macro into the code window. The macro is executed any time a cell is changed in the worksheet. It checks the cells in C12:C20, and if any of them contain a zero value, then the diagonal border is set for that cell.
You can easily change the macro to apply to a different range of cells or to check for a different condition when applying the borders. If you prefer, you can change the xlDiagonalUp constant to xlDiagonalDown, depending on which diagonal border you want applied.
