I have this GridView that looks like this.

<tg:RadGridView

tc:RadDockPanel.Dock="Top"

ItemsSource="{Binding Steps}"

SelectedItem=

"{Binding CurrentSelectedStep, Source={x:Static SizingApp:ProjectManager.Instance}, Converter={StaticResource PSSpecConverter}, Mode=TwoWay}"

Style="{StaticResource RadGridViewStyle}"

RowLoaded="RadGridView_RowLoaded">

<tg:RadGridView.ChildTableDefinitions>

<tg:GridViewTableDefinition />

<tg:RadGridView.HierarchyChildTemplate>

I've been trying to get this to have the rows be expanded after binding if there are Loads within Steps. However I can't figure out how to make them Expended by Default, and how to hide the IsExpandable click opener when there are no Loads within Steps. In the help file, it shows how to enable and disable IsExpandable on RowLoaded event. However, when binding occurs, nothing is updated as the RowLoaded doesn't fire. Can anyone comment on how to make the rows expanded by default, and which events to use to make the IsExpandable work as binding occurs?
