RadPanelBar Expand by Default

[Scott]

I am using RadPanelBar to populate the quick launch in SharePoint 2010. It works beautifully but I was curious if you could expand every node by default. Thanks.

Hello Scott,

If the RadPanelBar is databound, then the best approach is to use ContainerBindings (you can follow the approach described here) to bind the RadPanelBarItem IsExpanded property to a related property from your ViewModel. This will allow you to control which items to be expanded at any given moment. Still, please keep in mind that in order to expand more than one RadPanelBarItem at a time, you will need to set the ExpandMode property to Multiple.

Another approach you can use is to call the RadPanelBar ExpandAll() method when the RadPanelBar is loaded:

private void radPanelBar_Loaded(object sender, RoutedEventArgs e)
{
    (sender as RadPanelBar).ExpandAll();
}

I hope this info will help you. Please let us know if we can further assist you.

Thanks for the reply Tina. After taking a second look I am in the wrong forum.

I am trying to implement the ASP.NET Ajax version as shown below. Therefor I am implementing the PanelBar into the Sharepoint Master Page. Could you move my topic or pass it along? Thanks!

Hello Scott,

Let me suggest you handle the OnClientLoad event of the RadPanelBar and expand the RadPanelItems in this way:

function OnClientLoadHandler(sender, eventArgs)
{
  for (var i=0; i < sender.get_items().get_count(); i++)
  {
      sender.get_items().getItem(i).set_expanded(true);
  }
}

Please let me know if this was helpful.
