Urgent: Unable to change the RowSource property in a chart object through macro ot code.

Hi everybody,

In my database, I produce a report with charts. These charts are not to be based on records in a table but on calculated controls on the report itself.
To do that, I want to be able to change the rowsource property through either a macro or some code started when the report is open. (note: the Rowsourcetype is set to Value List and column count to 4.) It seems simple yet it does not work!

Both when I use a macro (SetValue) or the code below, I receive the following error message: “Run-time error ‘2455’: you entered an expression that has an invalid reference to the property RowSource.”

However, when I use the same code in a form, it works fine. Should I understand that what is true for a form in not true for a report. Or is there a way to solve this issue?

Thanks.

Arnaud


Private Sub Report_Open(Cancel As Integer)
    Dim Chartsource As String
    Chartsource = "Road ; Paved ; Maintainable ;  Maintained ;  Country ; .95 ; .50 ; .25 ; Region ; .10 ; .45 ; .35"
    Me!Network_condition_graph.RowSource = Chartsource
End Sub

I'm pretty sure that the rowsource cannot be changed at runtime.  Instead you need to open the report in design view change the rowsource and then open the report in preview/print mode.  E.g.

Sub chnggraph()

Dim Chartsource As String
Dim rpt As Report

 
DoCmd.OpenReport "Report1", acViewDesign
Set rpt = Reports("Report1")
Chartsource = "Road ; Paved ; Maintainable ;  Maintained ;  Country ; 0.95 ; .50 ; .25 ; Region ; .10 ; .45 ; .35"
rpt!Network_condition_graph.RowSource = Chartsource

Set rpt = Nothing
DoCmd.OpenReport "Report1", acViewPreview

End Sub
