ItemTemplateSelector Property (ISHeaderedItemsControl)



Gets or sets the Template Selector that is applied to the container element generated for each item.
Syntax
Public Property ItemTemplateSelector As DataTemplateSelector
Dim instance As ISHeaderedItemsControl
Dim value As DataTemplateSelector
 
instance.ItemTemplateSelector = value
 
value = instance.ItemTemplateSelector
public DataTemplateSelector ItemTemplateSelector {get; set;}
public:
property DataTemplateSelector^ ItemTemplateSelector {
   DataTemplateSelector^ get();
   void set (    DataTemplateSelector^ value);
}

Property Value

The Template Selector that is applied to the container element generated for each item. The default is null.
Remarks

Similar with ItemContainerStyleSelector, you can also create an ItemTemplateSelector by creating a class that inherit from DataTemplateSelector. This template selector allows you to apply different template on different item based on the logic describes in the template selector.

Example

The following example shows how to use DataTemplateSelector to create alternate item template in UXListBox.
