Declaration
Property Value
| Type | Description |
|---|---|
| DataTemplateSelector | A DataTemplateSelector descendant that chooses a template based on custom logic. |
Remarks
A template that defines the presentation of the group’s header is specified by the NavBarGroup.HeaderTemplate property. If you have more than one template that can be used to render the group header, 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 HeaderTemplateSelector property.
If both the NavBarGroup.HeaderTemplate and HeaderTemplateSelector 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 NavBarGroup.HeaderTemplate property is used.
