-This repository contains the sample that how to modify or disable shortcuts of EditControl.
+# How to Modify or Disable Shortcuts in WPF EditControl
+This example demonstrates how to disable or modify keyboard shortcuts in the Syncfusion WPF EditControl. By default, EditControl supports common shortcuts like Undo (Ctrl+Z) and Redo (Ctrl+Y). In some scenarios, you may want to override or disable these shortcuts to implement custom logic or restrict user actions.
 
-The EditControl Undo and Redo functionality can be modify or disable by using the IsUndoEnabled and IsRedoEnabled property of Editcontrol.
+## Why This Is Useful
+- **Custom Behavior**: Implement your own shortcut logic.
+- **Restrict Actions**: Disable Undo/Redo in read-only or controlled environments.
+- **Dynamic Control**: Enable shortcuts only under specific conditions.
 
-```C#
-public Window1()
-{
-Edit1.PreviewKeyDown += Edit1_PreviewKeyDown;
-}
-```
+## Key Approaches
+1. Disable Undo and Redo using properties:
+    - IsUndoEnabled = false
+    - IsRedoEnabled = false
+2. Intercept keyboard shortcuts using PreviewKeyDown:
+    - Apply conditional logic to enable or disable shortcuts dynamically.
 
-You can also use our PreviewKeyDown event to modify this Undo and Redo features using the following code:
+## Code Example
+**XAML**
+```XAML
+<syncfusion:EditControl Name="Edit1"
+                        Grid.Row="2"
+                        AllowDrop="True"
+                        Background="White"
+                        BorderBrush="Black"
+                        BorderThickness="0"
+                        EnableOutlining="False"
+                        FontFamily="Verdana"
+                        Height="400"
+                        Width="400" />
+```
 
+**C#**
 ```C#
-private void Edit1_PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
-{
-if(e.Key == Key.Z && (e.KeyboardDevice.Modifiers & ModifierKeys.Control) != 0)
+
+public partial class Window1 : Window
 {
-//Undo feature enable by checking the keys.
-Edit1.IsUndoEnabled = true;
-}
+    public Window1()
+    {
+        SfSkinManager.SetTheme(this, new Theme("Office2019Colorful"));
+        InitializeComponent();
+
+        Edit1.DocumentSource = @"../../Content.txt";
+
+        // Disable Undo and Redo
+        Edit1.IsUndoEnabled = false;
+        Edit1.IsRedoEnabled = false;
+
+        // Uncomment to enable dynamic shortcut handling
+        // Edit1.PreviewKeyDown += Edit1_PreviewKeyDown;
+    }
+
+    private void Edit1_PreviewKeyDown(object sender, KeyEventArgs e)
+    {
+        // Enable Undo only when Ctrl+Z is pressed
+        if (e.Key == Key.Z && (e.KeyboardDevice.Modifiers & ModifierKeys.Control) != 0)
+        {
+            Edit1.IsUndoEnabled = true;
+        }
+    }
 }
 ```
 
+## Notes
+- You can extend this logic to handle other shortcuts like Ctrl+Y, Ctrl+C, etc.
+- Use PreviewKeyDown for intercepting before default behavior executes.
