How can I change the SfAutoComplete cursor color in .NET MAUI

[Bryson Scales]

I would like to create a cursor color behavior for the SfAutoComplete similar to the one for an entry found here:  Customizing your controls with Platform Behavior | .NET Conf: Focus on MAUI

It would be awesome if you could also include the code for changing all other Syncfusion input cursors as well.

Thanks,

Bryson

Hi Bryson

Thank you for your inquiry about changing the cursor color for the .NET MAUI SfAutocomplete control. We've investigated this issue and developed a solution that should address your needs. Here's an overview of the approach we've taken:

Cursor Color: To change the cursor color, we've accessed the internal Entry control of SfAutocomplete and modified its native text field properties. This allows us to set the cursor color directly.

Selection Color: For the text selection color, we've used reflection to access the internal SfInputView and its SelectionColor property. This allows us to modify the selection color even though these elements are internal to the control.

We've implemented these changes in a sample project that demonstrates how to achieve the desired cursor and selection color modifications. The sample includes:

1.A custom behavior that can be attached to the SfAutocomplete control.

2.Platform-specific code to set the cursor color on Android, iOS, and Windows.

3.Reflection-based code to set the selection color across all platforms.

<syncfusion:SfAutocomplete>

    <syncfusion:SfAutocomplete.Behaviors>

        <local:AutocompleteCursorColorBehavior CursorColor="Green" />

    </syncfusion:SfAutocomplete.Behaviors>

</syncfusion:SfAutocomplete>

We've attached the sample project to this response for your reference. Please review it and let us know if this solution meets your requirements or if you need any further assistance.

Thanks for such a fast response! I was able to change the cursor color on android however, I would also need to change the thumb and highlight colors to match. Can you please provide the code to do this as well? Ideally, it would be awesome to have a single behavior that can handle all of the coloring in a single definition

Also, I forgot to add that it would be important to know how to do this on all android versions. Thanks!

Hi Bryson, 
 
Thank you for your update. Based on your request, we have reviewed and implemented a comprehensive solution to modify the cursor, selection highlight, and text selection handle colors in SfAutocomplete. We have tested this solution on both Android and iOS, and it is working as expected across different Android versions. Here's how our implementation handles various Android versions: 

  

For Android 10 (API 29) and above: 

1. Android provides direct API support through the official EditText properties 
2. We use the `TextCursorDrawable`, `TextSelectHandle`, `TextSelectHandleLeft`, and `TextSelectHandleRight` properties with the `SetTint` method 
3. This is the recommended approach as it uses the platform's dedicated APIs for customization 

For Android versions below API 29: 

1. Since direct API support is not available, we implemented a reflection-based approach 
2. This allows access to internal Android TextView and Editor fields that control cursor and handle appearances 
3. While reflection is generally not recommended for production, this is the only way to achieve consistent UI on older Android versions 

Please take a look at the updated sample project along with the output images we've attached. Let us know if this solution meets your requirements or if you need any further adjustments.
