Bind UWP ComboBox ItemsSource to Enum

Bind UWP ComboBox ItemsSource to Enum

To bind a UWP ComboBox control's ItemsSource property to an Enum, you can use the Enum.GetValues method to retrieve the values of the Enum and set the ComboBox's ItemsSource property to an IEnumerable of the Enum values.

Here's an example:

XAML:

<ComboBox x:Name="comboBox" />

C#:

using System; // Bind the ComboBox to the enum comboBox.ItemsSource = Enum.GetValues(typeof(MyEnum));

In this example, MyEnum is the Enum that we want to bind to the ComboBox. We use the Enum.GetValues method to retrieve the values of the Enum and set the ItemsSource property of the ComboBox to an IEnumerable of these values.

Note that when you bind an Enum to a ComboBox, the ToString method is used to display the Enum values in the ComboBox items. If you want to use a different display format, you can bind the ComboBox to a collection of custom objects that represent the Enum values, and use a DataTemplate to specify the display format.
