Thank you for writing.
Currently the only way to set the spacing between groups is by using the SpacingBetweenGroups
property of RadPanelBar in the following way:
|this.radPanelBar1.SpacingBetweenGroups = 20; |
A group's initial state can be set to "collapsed" by using the CollapseGroup
Hope that helps. If you have any additional questions, please do not hesitate to contact us.
All the best,
the Telerik team
