Change tab color based on a cell value
 

Does anyone know what code I would use in the worksheet event to change
the tab color of all 6 worksheets in my workbook based off a value in a
cell?

I would like all 6 tabs to be red if there is any value in cell V1 of
worksheet 1. If cell V1 is empty I don't want any tab color.

I'm also not sure how to reference worksheet 1 in the code because the
name of it changes depending on what's in two other cells of the
worksheet.

This is the code I have right now in the worksheet event.


Code:
--------------------
Private Sub Worksheet_Change(ByVal Target As Range)
Dim ws As Worksheet
Dim i As Long

If InStr(Target.Address, "$A$7") < 0 Or InStr(Target.Address, "$A$8") < 0 Then
For Each ws In Worksheets
i = i + 1
On Error Resume Next
If Not IsDate(Range("A7")) Then
ws.Name = "Cert Period " & i
Else
ws.Name = Format(ws.Range("A7"), "m-dd-yy") & " THRU " & Format(ws.Range("F7"), "m-dd-yy")
End If
If Err.Number < 0 Then
MsgBox "Could not rename sheet " & ws.Name, vbCritical, "Renaming Error"
Err.Clear
End If
Next ws
End If
End Sub
--------------------


(FYI - cells A7 & F7 are merged cells.)

Any help is greatly appreciated. Thanks.

Change tab color based on a cell value
 

Could you use worksheets(1)?

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Dim ws As Worksheet
Dim i As Long

If Target.Cells.Count 1 Then Exit Sub
If Intersect(Target, Me.Range("a7:a8")) Is Nothing Then Exit Sub

For Each ws In Worksheets
i = i + 1
On Error Resume Next
'did you mean ws.range("a7")
'or me.range("a7")
If IsDate(ws.Range("A7")) Then
ws.Name = Format(ws.Range("A7"), "m-dd-yy") _
& " THRU " & Format(ws.Range("F7"), "m-dd-yy")
Else
ws.Name = "Cert Period " & i
End If
If Err.Number < 0 Then
MsgBox "Could not rename sheet " & ws.Name, vbCritical, _
"Renaming Error"
Err.Clear
End If
If Me.Parent.Worksheets(1).Range("a7") = "" Then
'do nothing
Else
ws.Tab.ColorIndex = 3
End If
Next ws

End Sub

I (arbitrarily) changed a couple of things. You can change them back if you
don't like them.

I find this more difficult to understand:
If InStr(Target.Address, "$A$7") < 0 Or InStr(Target.Address, "$A$8") < 0 Then
than:
If Intersect(Target, Me.Range("a7:a8")) Is Nothing Then Exit Sub

And instead of checking the negative, I like to check the positive. But that
means the Then portion and the Else portion have to swap locations:

If Not IsDate(Range("A7")) Then
ws.Name = "Cert Period " & i
Else
ws.Name = Format(ws.Range("A7"), "m-dd-yy") _
& " THRU " & Format(ws.Range("F7"), "m-dd-yy")
End If

becomes

If IsDate(ws.Range("A7")) Then
ws.Name = Format(ws.Range("A7"), "m-dd-yy") _
& " THRU " & Format(ws.Range("F7"), "m-dd-yy")
Else
ws.Name = "Cert Period " & i
End If

Change tab color based on a cell value
 

Thanks for your help on the code. The tab coloring isn't quite right.
No matter what I have in the cell, all the tabs are red. Any ideas?

This is the portion that does the checking/work:

If Me.Parent.Worksheets(1).Range("a7") = "" Then
'do nothing
Else
ws.Tab.ColorIndex = 3
End If

What's in the leftmost worksheet in cell A7?

As long as there's something in it, the tab color will be red.

Change tab color based on a cell value
 

I'm not sure what you mean when you ask . . . . What's in the leftmost
worksheet in cell A7?

I tried using your code but it doesn't work with the names of the
sheets with Cert Period & i when cell A7 is blank. I inserted your
part of the code with the coloring of the tabs and then I made some
changes but I keep getting the same result that all the tabs are
colored when I use your code and when I made the change.

The cell I want to base coloring or not coloring the tabs is cell V1.
FYI - if cell V1 in the first worksheet has a value in it, that value
is copied to cell V1 of the rest of the worksheets. So it doesn't
matter which worksheet is referenced, if there's a value in cell V1 of
any of the worksheets, I want all tabs to be red. If cell V1 of any of
the worksheets is empty, I want all the tabs to not be colored.


Code:
--------------------
Private Sub Worksheet_Change(ByVal Target As Range)
Dim ws As Worksheet
Dim i As Long

If InStr(Target.Address, "$A$7") < 0 Or InStr(Target.Address, "$A$8") < 0 Then
For Each ws In Worksheets
i = i + 1
On Error Resume Next
If Not IsDate(Range("A7")) Then
ws.Name = "Cert Period " & i
Else
ws.Name = Format(ws.Range("A7"), "m-dd-yy") & " THRU " & Format(ws.Range("F7"), "m-dd-yy")
End If
If Err.Number < 0 Then
MsgBox "Could not rename sheet " & ws.Name, vbCritical, "Renaming Error"
Err.Clear
End If
If Not IsDate(Range("V1")) Then
ws.Tab.ColorIndex = -xlColorIndexAutomatic
Else
ws.Tab.ColorIndex = 3
End If
Next ws

End If
End Sub
--------------------


Cell V1 is not merged. It's formatted with a date format. I'm not
sure what the problem could be.

I messed up when I used A7. It should have been V1.

If Me.Parent.Worksheets(1).Range("a7") = "" Then

I did notice you used A7 instead of V1. I changed a7 to v1 in the code
and when v1 is empty, nothing happens, when v1 has a date in it,
nothing happens.

If I leave a7 in the code instead of v1 and enter a date in a7, all the
tabs will turn red, when I remove the date from a7, all the tabs have no
color - which is really great but why can't I change the code to v1 and
have it work the way it does with a7?

It looks like you used a cross between the code I suggested and your existing
code. How about just trying the code I suggested (with the A7/V1 change) and
see what happens?

When I use your code exactly how you have it with the a7/v1 conversion,
nothing happens. The tabs don't change color with a value in v1 and
they don't change when v1 is empty.

You didn't include the code to change the .colorindex back if V1 was empty. But
this code worked fine for me:

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Dim ws As Worksheet
Dim i As Long

If Target.Cells.Count 1 Then Exit Sub
If Intersect(Target, Me.Range("a7:a8")) Is Nothing Then Exit Sub

For Each ws In Worksheets
i = i + 1
On Error Resume Next
'did you mean ws.range("a7")
'or me.range("a7")
If IsDate(ws.Range("A7")) Then
ws.Name = Format(ws.Range("A7"), "m-dd-yy") _
& " THRU " & Format(ws.Range("F7"), "m-dd-yy")
Else
ws.Name = "Cert Period " & i
End If
If Err.Number < 0 Then
MsgBox "Could not rename sheet " & ws.Name, vbCritical, _
"Renaming Error"
Err.Clear
End If
If Me.Parent.Worksheets(1).Range("v1") = "" Then
ws.Tab.ColorIndex = xlNone '<--- Added
Else
ws.Tab.ColorIndex = 3
End If
Next ws

End Sub

Are you sure you put it in the correct location--in the worksheet module that
owns the A7:A8 that you want to monitor?

If it's working fine for you then it must be something with the layout
of my spreadsheet. I un-merged v1. I copied the code how you wrote it
in your recent post and I still couldn't get it to work.

So far doing the code separately how I posted in post #9 seems to be
working.

Thanks for all your time.

Merged cells can cause many problems. I try to avoid them unless I absolutely
have to use them.
