+
+## Description
+
+When moving or changing a recurring appointment in UI for WinForms Scheduler, a warning message appears asking whether to modify the entire recurring appointment or a single occurrence. I want to disable this message or replace it with custom text.
+
+
+## Solution
+
+To disable the recurrence change message, override the dragging behavior of the Scheduler using the following code:
+
+````C#
+
+public SurroundingClass()
+    {
+        InitializeComponent();
+        this.RadScheduler1.SchedulerElement.DragDropBehavior = new CustomDraggingBehavior(this.RadScheduler1.SchedulerElement);
+    }
+
+    public class CustomDraggingBehavior : AppointmentDraggingBehavior
+    {
+        public CustomDraggingBehavior(SchedulerVisualElement activeOwner) : base(activeOwner)
+        {
+        }
+
+        protected override bool ValidateOccurrenceDropTarget(DateTime targetStartDate, DateTime targetEndDate, bool allDay)
+        {
+            return true;
+        }
+    }
+
+````
+
+Alternatively, replace the message text by specifying the `RadSchedulerStringId.RecurrenceDragDropCreateExceptionDialogText` string in the `RadSchedulerLocalizationProvider`. Refer to the Telerik documentation for [localization and translating strings](https://docs.telerik.com/devtools/winforms/scheduler/localization/translating-strings).
