Customize Entry Cursor Color

Description
This article shows you how to access the native element through the .NET MAUI handler for RadEntry via the RadMauiEntry object.
Step 1.
Subscribe to the HandlerChanged event of the RadEntry you want to customize.
MyRadEntry.HandlerChanged += Entry1_HandlerChanged;
Step 2.
In the event handler, access the RadEntry Handler's PlatformView property. From there, you can access all the native platform's features.
private void Entry1_HandlerChanged(object sender, EventArgs e)
{
// Make sure the PlatformView is available
if ((sender as RadEntry)?.Handler?.PlatformView is RadMauiEntry nativeEntry)
{
// Step 3. change the desired native-specific properties
#if ANDROID
nativeEntry.EditText.TextCursorDrawable?.SetColorFilter(new Android.Graphics.PorterDuffColorFilter(Android.Graphics.Color.Red, Android.Graphics.PorterDuff.Mode.Darken));
#elif __IOS__
nativeEntry.TextField.TintColor = UIKit.UIColor.White;
#endif
}
}
Alternate Approach
If you have many instances of the control on a single view, or throughout your app, you may want to consider creating your own custom class and subclassing the RadEntry. In the custom control's class you can override the OnHandlerChanged instead of subscribing to an event handler.
public class MyCustomTelerikEntry : Telerik.Maui.Controls.RadEntry
{
protected override void OnHandlerChanged()
{
// DO NOT SKIP THIS, or you risk breaking internal logic
base.OnHandlerChanged();
// Step 1. Make sure the PlatformView is available
if (this.Handler?.PlatformView is RadMauiEntry nativeEntry)
{
// Step 2. change the desired native-specific properties
#if ANDROID
nativeEntry.EditText.TextCursorDrawable?.SetColorFilter(new Android.Graphics.PorterDuffColorFilter(Android.Graphics.Color.Red, Android.Graphics.PorterDuff.Mode.Darken));
#elif __IOS__
nativeEntry.TextField.TintColor = UIKit.UIColor.White;
#endif
}
}
}
Known Limitations
It is not possible to apply caret customization on the following platforms:
- Windows - WinUI3, and WinApp SDK, just does not have any access the caret of the native TextBox.
- MacCatalyst - Due to a .NET MAUI issue, changes to TextField.HintColor is not respected on MacCatalyst.
If either of those situations change, then these limitations may be outdated and you can attempt the customization again.
