Hi,
I have created a LineSeries chart that uses a Drill Down tool tip to display further information about the selected line.
All information that is charted, is pulled from a WCF/SQL Service. The initial chart I have created runs fine, however when trying to create the drill down chart, the chart is rendered before the WCF service returns the latest results.
Is there a way to either wait for the WCF to return its results, or force the tool tip to open during the GetCompleted() method?

Hello Drew,
So you are creating a RadChart when tooltip is displayed?
Why don't you just put the data later (when it becomes available) in ItemsSource of the drilled-down chart? The chart will re-render with the new data.
An additional limitation to this scenario, which needs to be mentioned, is that Silverlight only supports asynchronous communication with the service. Additionally, there is no api to show the tooltip for the chart progranatically.
Let me know if I am leaving something out.
