Property Value
| Type | Description |
|---|---|
| DataTemplateSelector | A DataTemplateSelector descendant that chooses a template based on custom logic. |
Remarks
A template that defines the presentation of node footer summary items is specified by the TreeListView.NodeFooterSummaryItemTemplate property. If you have more than one template that can be used to render node summary 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 NodeFooterSummaryItemTemplateSelector property.
If both the TreeListView.NodeFooterSummaryItemTemplate and NodeFooterSummaryItemTemplateSelector are specified, row details are rendered using the template returned by the template selector. If the template selector returns null, the template specified by the TreeListView.NodeFooterSummaryItemTemplate property is used.
