You can edit the default ControlTemplate
of the RadExpander
and set the HeaderButton
. This way teh RadExpander
header will be hidden. Than you can control the IsExpanded
property of the control through a button click.
I attached a sample project to get you started. The same approach can be implemented in an MVVM approach by binding the RadExpander.IsExpanded
property to a business property and then use a command to control this property in the view model through the button Command
. Please have a look at the sample and let me know if this is what you had in mind.
