Syntax
Public Property ItemContainerStyleSelector As StyleSelector
Dim instance As ISHeaderedItemsControl
Dim value As StyleSelector
 
instance.ItemContainerStyleSelector = value
 
value = instance.ItemContainerStyleSelector
public StyleSelector ItemContainerStyleSelector {get; set;}
public:

   StyleSelector^ get();
   void set (    StyleSelector^ value);
}

Property Value

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

ItemContainerStyleSelector is used to perform certain validation before applying the style. This approach can be used to alternate style between items, or highlighting certain items based on certain condition and many other scenarios.

To use this approach you need to create a class that inherit from StyleSelector class.
