Extenders: Using complex types inside my Behavior.js javascript?

I added some complex types to my PanelExtender.vb that represents lists of numerical values:

Public Class ChartPanelExtenderInherits ExtenderControlBase(Of ChartPanelProperties, Panel)Private _dataseriesAs ArrayListPublic Sub AddSerie(ByVal p_serieAs DataSerie) _dataseries.Add(p_serie)End Sub Public Class DataSeriePrivate _valuesAs ArrayListPrivate _nameAs String Public Sub New(ByVal serieNameAs String) _name = serieNameEnd Sub Public Sub AddValue(ByVal p_valueAs Integer) _values.Add(p_value)End Sub Public Property Name()As String Get Return _nameEnd Get Set(ByVal valueAs String) _name = valueEnd Set End Property End Class End Class

Although I can easily create and add data series to my PanelExtender on the server-side (aspx page):

 Public Sub Page_load(ByVal sender As Object, ByVal e As EventArgs) Dim mySerie As New ChartPanelExtender.DataSerie("MyData") mySerie.AddValue(2) mySerie.AddValue(3) mySerie.AddValue(4) ' this is the name of the control in the page ChartPanelExtender1.AddSerie(mySerie) End Sub

I cannot figure how to access this data inside my javascript PanelBehavior.js code?
Do I need to somehow serialize/deserialize it manually?
How can I pass this data to the PanelBehavior.js script?

Any suggestions would be appreciated including telling me I am way off and giving an alternative hehe. All I really need is a way to pass data series to the behavior script.

Thanks in advance

PascalThe typical way of getting information to a JS behavior is via one of its properties. Your server code might transform the list somehow so that it can be safely passed to the behavior in a string (ex: [a, b, c] -> "a,b,c") and then the behavior can transform the string back into the data it represents. We're considering adding JSON support to this scenario so that more complex data types could be communicated more easily, but haven't done so yet, so the ->string-> technique may be a good choice for now. Hope this helps!
Okies, will see if JSON gets added in next CTP.
Thanks for the reply :)
