Hello Joe,

Thank you for the question.

You are correct. Currently, only the ExplorerBar layout is available in the Visual Style Builder. Properties specific to the other GroupStyles could be only programmatically set.

Regarding the captions of the groups, the ExplorerBar GroupStyle share common properties with the OutlookNavPane GroupStyle. So, the properties that you apply to the captions in Visual Style Builder will be applied to a RadPanelBar with OutlookNavPane GroupStyle.

In case you want to set properties of OutlookNavPane's specific elements, RadControlSpy will be of great help to you. It will show you RadPanelBar's elements hierarchy and you will be able to set various properties of these elements through code. 

If there is something specific that you want to set, but you need help, I will be glad to assist you further.

Dealing with the captions, I believe I am trying to modify the Root > RadPanelBarElement > OutlookStyleElement > RadPanelBarVisualElement.

It looks nothing like Outlook 2007 does and there are a lot of things I want to change, but for example, it defaults to black, cenetered, Sans Serif, 8.25pt text.  I am trying to get this to be "21, 66, 139", left, Arial, 12pt bold text.

Its funny, the ASP.Net ajax panelbar (here) gets it perfect, this is exactly how I want things to look.

Hello Joe,

Thank you for getting back to me.

I have attached a sample project which demonstrates how you can set the desired properties. In addition, you can refer to our Knowledge Base article which explains how to set the orange style of the selected groups: Programmatically achieve Outlook-like captions.

I hope this helps. If you have additional questions, feel free to contact me.

All the best,
