[Solved] WCF Service in Silverlight

[John Giblin]

I have a silverlight app where I am populating a few controls (comboboxes and date picker controls). After that is done, I wanted to set the default fields. Based on controls values it would make a service call which will populate a radgridview. 

Since the service calls are all async, I am not sure when the fields have been populated and default values are set to run the next service call

any ideas
