hello anand, you can refer my reply to another question which was similar to this "https://www.c-sharpcorner.com/Forums/combo-box-behavior-properties-to-use-first-char-typed" but i can explain you again, you need write behaviour in wpf to achive this and bind with your combobox control. i will write blog on this if this topic is not avaible in other forums. public static class EditableComboBoxBehavior { public static readonly DependencyProperty AcceptsEnterKeyProperty = DependencyProperty.RegisterAttached( "AcceptsEnterKey" , typeof ( bool ), typeof (EditableComboBoxBehavior), new PropertyMetadata( default ( bool ), OnEnterKeyPress)); public static void SetAcceptsEnterKey(DependencyObject element, bool value) { element.SetValue(AcceptsEnterKeyProperty, value); } public static bool GetAcceptsEnterKey(DependencyObject element) { return ( bool )element.GetValue(AcceptsEnterKeyProperty); } private static void OnEnterKeyPress(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs eventArgs) { var element = (UIElement)dependencyObject; if (( bool )eventArgs.NewValue) { element.PreviewKeyDown += PreviewKeyDown; element.KeyUp += KeyDown; } else { element.PreviewKeyDown -= PreviewKeyDown; element.KeyUp -= KeyDown; } } // implemented KeyDown and PreviewKeyDown methods to set the focus of the elemtn in combox box and set the selection etc etc. } xmal part "True" ItemsSource= "{Binding Items}" SelectedValue= "{Binding Item}" Text= "{Binding Item, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" StaysOpenOnEdit= "False" IsTextSearchCaseSensitive= "False" EditableComboBoxBehavior.AcceptsEnterKey= "True" ShouldPreserveUserEnteredPrefix= "True" > let me know if that works for you
