Hierarchical GridView Rows Expanded

[Ristogod]

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:GridViewTableDefinition />
        </tg:GridViewTableDefinition>
    </tg:RadGridView.ChildTableDefinitions>
    <tg:RadGridView.HierarchyChildTemplate>
        <DataTemplate>
            <tg:RadGridView
                    ItemsSource="{Binding Loads}"
                    SelectedItem="{Binding CurrentSelectedLoad, Source={x:Static SizingApp:ProjectManager.Instance}, Converter={StaticResource PSSpecConverter}, Mode=TwoWay}"
                    Style="{StaticResource RadGridViewStyle}">
                <tg:RadGridView.Columns>
                    <tg:GridViewDataColumn DataMemberBinding="{Binding Name}"
                            Header="{Resx ResxName=PSSPECApplication.Controls.ProjectControlResources, Key=StepSummary_LoadColumn_Header}"

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?

Is this link to the blog post example still valid?  I keep getting a server error and have tried several times over a couple of days.

Please use this link instead. Do you still continue to get that error ?

That link works!  Thank you very much. -LW

Would you please update the invalid blog post link in your response.  And, since this is the 3rd or 4th time I've asked the exact same question, would you please have something spider through your forums and fix up the blog URLs?

Thanks very much,

Hello Lynne,

We are currently refactoring our blogs due to the many broken links that suddenly appeared after a bug in the URL generator. Very soon we will apply major fix that should fix almost all broken links in our blogs and I hope that after this fix you want experience anymore such issues.

All the best,
