Re: Silverlight Combobox not binding correctly on all machines.

Hi all, Never mind, we've figured out what it was. When the set property was called, it called an Update Property method in the base class to hide the details of the property it ultimately had to raise the change event for. In the base class, it used reflection to identify the property name,

Silverlight Combobox not binding correctly on all machines.

Re: Silverlight RIA Services

Hi Shingi, It sounds like the object does not exist within the generated code within the Silverlight component. This means that the object is not shared properly from the web app. There are a number of reasons for this - perhaps you don't have an [EnableClientAccess] attribute on your class?

Hi Greg, One possibility is to change the default editor that it opens with. This is actually what I do sometimes to speed up xaml page loads. The down side is that you lose intellisense - but if you're having serious problems with crashing this might be a better option. To do this, right-cli
