GridViewHeaderRowPresenter.ColumnHeaderTemplateSelector Property

Definition

Gets or sets a DataTemplateSelector that provides logic that selects the data template to use to display a column header.

public:
 property System::Windows::Controls::DataTemplateSelector ^ ColumnHeaderTemplateSelector { System::Windows::Controls::DataTemplateSelector ^ get(); void set(System::Windows::Controls::DataTemplateSelector ^ value); };
public System.Windows.Controls.DataTemplateSelector ColumnHeaderTemplateSelector { get; set; }
member this.ColumnHeaderTemplateSelector : System.Windows.Controls.DataTemplateSelector with get, set
Public Property ColumnHeaderTemplateSelector As DataTemplateSelector

Property Value

The DataTemplateSelector that chooses the DataTemplate to use to display each column header. The default is null.

Remarks

If the ColumnHeaderTemplate property and the ColumnHeaderTemplateSelector property are both set, the ColumnHeaderTemplate takes precedence.

When you implement this class as part of a GridView view mode, the value of this property is bound to the value of the ColumnHeaderTemplateSelector property on the GridView.

You can customize column headers in a GridView view mode by using a variety of properties that are found in this class and in related classes. For more information about these properties, and about the precedence between them, see GridView Column Header Styles and Templates Overview.
