Hi Matthias Schuster,
There is no built in functionality in the breadcrumb for this scenario. However I can suggest doing the following:
- RadBreadCrumb contains many RadSplitButtonElements which you can extract from the Children collection of RadBreadCrumbElement's StripLayoutPanel. RadBreadCrumbElement's instance is the only child element of the Children collection of RadBreadCrumb's RootElement. An instance of RadBreadCrumbElement's StripLayoutPanel can be gotten by using the Children collection of RadBreadCrumbElement where the StripLayoutPanel is the third child.
- Once you have the instances of the breadcrumb's parts you can subscribe to the Click event or MouseDown, MouseUp and modify the SelectedNode property of RadTreeView.
- Please keep in mind that the bread crumb is updated when an selection in RadTreeView is made.
