Declaration
Property Value
| Type | Description |
|---|---|
| DataTemplateSelector | A DataTemplateSelector descendant that chooses a template based on custom logic. |
Remarks
A template that defines the visualization of group headers represented within the group button panel is specified by the NavigationPaneView.GroupButtonTemplate property. If you have more than one template that can be used to render these group headers, 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 GroupButtonTemplateSelector property.
If both the NavigationPaneView.GroupButtonTemplate and GroupButtonTemplateSelector 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 NavigationPaneView.GroupButtonTemplate property is used.
