Hey deeraj its simple try it. i have tried it in winform, you did not mention winforms or wpf or uwp using System; using System.Windows.Forms; namespace LoadEnumIntoComboBox { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private enum Books { VisualStudio, Xamarin, AndriodStudio, django, Atom } private void Form1_Load( object sender, EventArgs e) { comboBox1.Items.AddRange(Enum.GetNames( typeof (Books))); comboBox1.SelectedIndex = 0; } } }

I have a helper class which exposes a property to get the enum type so that I can resolve the enum values. public static Type GetEnum(DependencyObject obj) { return (Type)obj.GetValue(EnumProperty); } public static void SetEnum(DependencyObject obj, string value) { obj.SetValue(EnumProperty, value); } public static readonly DependencyProperty EnumProperty = DependencyProperty.RegisterAttached( "Enum" , typeof (Type), typeof (EnumHelper), new PropertyMetadata( null , OnEnumChanged)); Get the values of the enum and set it as ComboBox ItemsSource. private static void OnEnumChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { var control = sender as ItemsControl; if (control != null ) { if (e.NewValue != null ) { var _enum = Enum.GetValues(e.NewValue as Type); control.ItemsSource = _enum; } } } Now the ComboBox will bind to the enum values, if we set the enum value in XAML. public enum Designation { SoftwareEngineer, TeamLead, ProductManager } "Designation" Margin= "5" Grid.Row= "5" SelectedItem= "{Binding Designation, Mode=TwoWay}" local:EnumHelper.Enum= "{x:Type local:Designation}" >
