Missing chart elements after restoring chart from template

Hi,

I've noticed that if I restore my chart from session during postback using the following method (as demonstrated in the examples):

Code: Select all

Dim tmpChart As MemoryStream = New MemoryStream()
WebChart.Chart.Export.Template.Save(tmpChart)
Session.Add("tmpChart", tmpChart)

and

Code: Select all

Dim tmpChart As MemoryStream = New MemoryStream()
tmpChart = CType(Session("tmpChart"), MemoryStream)
tmpChart.Position = 0
WebChart.Chart.Import.Template.Load(tmpChart)

that some chart elements dont seem to get drawn again - in particular the arrow from the annotation to the callout (i.e. I have a number of custom annotations that are positioned above series points with a line going from the point to the annotation and although the text area gets restored the line doesn't) . Can you confirm whether this is correct?

Thanks,

Norman

Hi Norman,

Thanks for reporting. I could reproduce this one and I think it's a bug, which I have added to the defect list (TF02014078) to be fixed.

Hi Narcís,

No problem. You may wish to do a more thorough check than I did. I've noticed also that the shadow setting on the annotation doesn't get retained (e.g. in my project I had them hidden however they were displayed when I restored the chart). There may be others?
