Expand Attribute
What keywords can go inside the expand input variable?
I know its navigation related but I cant seem to find any documentation that tells me exactly what values are allowed.
I am not exactly sure about the nature of your use case, but if you are talking about the Expand and Collapse input parameters of Containers or Dynamic Panels, these can be triggered by Events. Any Event should work : Button Clicked, SelectionChanged, ServiceInvokeComplete...
Make sure to check the "EnableExpandCollapse" checkbox in the Container of Dynamic Panel's properties to allow this functionality to work.
