Question

FormatConditions

Asked by: ohgee

Hi
Need help please, with the following code.
Am trying to change datasheet cell colors when certain conditions are true. The code runs ok but cells do not change color.
When I step thru the debugger, under conditions where C2 = 1, I can see that 1 is passed to C2 and I can see that color 9553390 is passed to
the .BackColor property. So not sure why the datasheet cells are not changing color.
Is it because I need an array or loop statement to step thru all the records.
Need some guidance please
Thanks

Private Sub Form_Load()
 
Dim Compulsory As Integer
Dim c2 As Integer
Dim BColor
 
BColor = 9553390
 
Compulsory = IIf(DLookup("RxTypeID", "RxType", "Compulsory = False"), 0, DLookup("RxTypeID", "RxType", "Compulsory = True"))
 
c2 = IIf(IsNull(Me.Requirement) Or (Compulsory = 0), 1, 0)
 
With Me.Requirement
    .FormatConditions.Add acExpression, acEqual, "c2 = 1"
    .BackColor = BColor
End With
 
End Sub

Are you talking about the data grid cells ?

I am using an Access form, in datasheet mode; I think I should be using FormatConditions to conditionally modify cell properties. Not sure about datagrids. Thanks  

 

by: ohgeePosted on 2009-02-04 at 16:04:49ID: 23555217

Read in Access 2000 Programming for Dummies that FormatConditions requires a form control as the third parameter; have created an unbound text box called Status; the code runs but still cell does not change color. When testing the code the correct values appear to be passing so really should work ... 

Private Sub Form_Load()
 
Dim Compulsory As Integer
Dim c2 As Integer
Dim BColor
 
BColor = 9553390
Compulsory = IIf(DLookup("RxTypeID", "RxType", "Compulsory = False"), 0, DLookup("RxTypeID", "RxType", "Compulsory = True"))
c2 = IIf(IsNull(Me.Requirement) Or (Compulsory = 0), 1, 0)
 
With Me.Status
    .Value = c2
    .Visible = False
End With
 
With Me.Requirement
    .FormatConditions.Add acExpression, acEqual, "[Status] = 1"
    .BackColor = BColor
End With
 
End Sub

ohgee,

A few notes:
1. You did not give BColor a datatype when you declard it
2. Why not use conditional formatting from the menu, and not code it here?
3. If you want to build your own, then just use something like this:
    If XXX=YYY then
        ZZZ.BackColor=AAA
    else
        ZZZ.BackColor=vbWhite
    End If

4. When I commented out lines 8 and 9, (in your code above) and set a default vale of 1 for "Status", the "Requirement" textbox did indeed change color.

5. Try this code on the Open Event, unless there is a specific reason why it has to be on the Load event.
(Remember, you can cancel the Open event, not the Load event)

Thanks for these comments.
Have given BColor a datatype.

I did want to solve by using the menu conditional format option but could not figure how to do it. The color must fire only if one or another conditions are true, and one of the conditions is based on a table that is not linked to the form. So I guess I need a DLookup for that; hence line 8 and 9.

I tried the code on Open Event but does not work. The really strange thing is that if I step thru the code the correct values are being passed. For example I can get status to be 1 and color 9553390
but the instruction does not change the cell color in the datasheet.

I'm not strong on coding (slowly getting to understand it) and I wonder if I dont need a loop; the cell that must change color is on a table at the end of three-table relationship

OK,

Then can you post a sample of your database (with sample data) that simulates this issue?
Post the sample with no code.

Then expain what textbox must change format.
Also state what the conditions are that will trigger the change.

For example:
"The format of the textbox XXX must change based on the value of YYY in table ZZZ
"If the value of YYY is AAA then the backcolor of XXX should be 9553390"

I am sure that any of us can help you.

Thanks
