How do I force the XamWebGrid's expansion indicator to be visible at all times, even if the child collection is null? I want to lazy load the child collection when the expansion indicator is clicked, but the expansion indicator does not show if the child collection is null. The WPF grid has the option to show or hide the expansion indicator regardless of the state of the child collection, does the same exists in the Silverlight version?
Currently this feature is not available on the XamWebGrid.
Is this a planned feature that will be implemented in the next release? If not, can you add it to the feature list?
