Gets or sets an object that chooses a template for items representing groups within the overflow panel, based on custom logic. This is a dependency property.
NuGet Package: DevExpress.Wpf.NavBar
A DataTemplateSelector descendant that chooses a template based on custom logic.
A template that defines the visualization of items representing groups within the overflow panel is specified by the NavigationPaneView.OverflowGroupTemplate property. If you have more than one template that can be used to render these items, you can implement custom logic to choose the required template. To do this, derive from the DataTemplateSelector class, implement the SelectTemplate method that returns a template which meets the required condition, and assign it to the OverflowGroupTemplateSelector property.
If both the items representing groups within the overflow panel and OverflowGroupTemplateSelector are specified, a group item is rendered using the template returned by the template selector. If the template selector returns null, the template specified by the items representing groups within the overflow panel property is used.
