I have a graphics layer that whose graphics are displayed as clusters.
We have a Busy Indicator that we pop up during long calculations to let the user know that something is happening. I would like to pop up this indicator during the clustering, and have it go away once the clusters have done drawing on the screen. I can turn it on, but I am not able to capture a "done rendering" event to turn off the indicator. I've tried capturing the LayoutUpdated event on the Map, but it gets sent several times and am not able to determine which one is the graphics layers saying its done rendering. I found the OnClusteringCompleted event of the GraphicsClusterer and but I am unable to capture it.
We are using ArcGIS 9.3.1 and Silverlight 4.
Any suggestions on how to accomplish what I want?
