Questions tagged [itemtemplateselector]

Gets or sets the custom logic for choosing a template used to display each item.

You use the ItemTemplate to specify the visualization of the data objects. If you have more than one template defined and want to supply logic to return a template to use, then you use this property. Note that this property is ignored if ItemTemplate is set. The ItemsControl provides great flexibility for visual customization and provides many styling and templating properties. Use the ItemContainerStyle property or the ItemContainerStyleSelector property to set a style to affect the appearance of the elements that contain the data items. For example, for ListBox, the generated containers are ListBoxItem controls; for ComboBox, they are ComboBoxItem controls. To affect the layout of the items, use the ItemsPanel property. If you are using grouping on your control, you can use the GroupStyle or GroupStyleSelector property.
