+
+## Description
+
+I am trying to change the cursor color of the [UI for .NET MAUI AutoComplete](https://www.telerik.com/maui-ui/documentation/controls/autocomplete/overview) control on Android and on iOS to match the color of other input fields in the application. However, the available documentation for customizing the cursor is for versions 5.2.0 to 7.0.0 and is incompatible with the current version. Since version 8.0.0, the control uses `RadTextInput` internally instead of `RadEntry`, which requires different logic for cursor customization.
+
+This knowledge base article also answers the following questions:
+- How to update AutoComplete cursor color on mobile?
+- How to handle breaking changes for cursor customization in AutoComplete after version 8.0.0?
+- How to apply native logic to change cursor color in AutoComplete control?
+
+## Solution
+
+To modify the cursor color in the AutoComplete control, follow these steps:
+
+1. Handle the `Loaded` event of the AutoComplete control to locate the internal `RadTextInput` control and apply the necessary native logic.
+2. Use the `Handler` property of `RadTextInput` to update the cursor color for Android and iOS.
+
+```csharp
+private void autoComplete_Loaded(object sender, EventArgs e)
+{
+    var textInput = ChildOfType<RadTextInput>(this.autoComplete);
+    if (textInput != null)
+    {
+        var handler = textInput.Handler;
+        if (handler == null)
+        {
+            textInput.HandlerChanged += this.OnTextInputHandlerChanged;
+        }
+        else
+        {
+            this.UpdateNativeElement(handler);
+        }
+    }
+}
+
+private void OnTextInputHandlerChanged(object sender, EventArgs e)
+{
+    var textInput = (RadTextInput)sender;
+    this.UpdateNativeElement(textInput.Handler);
+    textInput.HandlerChanged -= this.OnTextInputHandlerChanged;
+}
+
+private void UpdateNativeElement(IViewHandler handler)
+{
+    var nativeEntry = handler.PlatformView as Telerik.Maui.Platform.RadMauiTextInput;
+    if (nativeEntry != null)
+    {
+#if ANDROID
+        nativeEntry.TextCursorDrawable?.SetColorFilter(new Android.Graphics.PorterDuffColorFilter(Android.Graphics.Color.Red, Android.Graphics.PorterDuff.Mode.Darken));
+#elif __IOS__
+        nativeEntry.TintColor = UIKit.UIColor.Red;
+#endif
+    }
+}
+
+internal static T ChildOfType<T>(View visualElement) where T : View
+{
+    if (visualElement == null)
+    {
+        return null;
+    }
+
+    foreach (var item in VisualTreeElementExtensions.GetVisualTreeDescendants(visualElement))
+    {
+        if (item is T targetElement)
+        {
+            return targetElement;
+        }
+    }
+
+    return null;
+}
+```
+
+3. Add sample AutoComplete definition in XAML:
+
+```xaml
+<VerticalStackLayout>
+    <telerik:RadAutoComplete x:Name="autoComplete"
+                             Loaded="autoComplete_Loaded"
+                             Placeholder="Search here..." />
+</VerticalStackLayout>
+```
+
+4. Add sample data for the AutoComplete source:
+
+```csharp
+this.autoComplete.ItemsSource = new List<string>()
+{
+    "Freda Curtis",
+    "Jeffery Francis",
+    "Eva Lawson",
+    "Emmett Santos",
+    "Theresa Bryan",
+    "Jenny Fuller",
+};
+```
