DrillDown don't work when binding WCF Service

[Shaojian]

Since I have a huge org chart and I have to use the WCF service for on-demand loading, but I see the drilldown don't work since it cannot get the NodeID.

The error as follow: Object reference not set to an instance of an object.



[NullReferenceException: Object reference not set to an instance of an object.]

Hi Shaojian,

How is your WCF service configured? Does it return the correct data? Please paste the markup of the OrgChart and code of the service.

Thanks.
