Not able to draw the signature when it is inside scrollview on iOS 29

[Simon Maystre]

I have signature pad inside the scrollview. This is working fine when I run the app on iOS 18.6 or 17.2.

But when the app is run on iOS 26, I am not able to draw the signature and it is capturing the scrolling, not the actual drawing

I have tried using the latest version of of syncfusion but still not working

Hi Simon Maystre,

 

We have created a sample project using .NET 9 and tested it on:

• iPhone 17 with iOS 26.0
• iPad A16 with iOS 26.0

 

The signature pad was placed inside a ScrollView. We've attached both the sample project and a demo video for your reference. We did not face the reported issue from our end and have checked these devices as well.

 

To help us investigate further and provide a tailored solution, could you please share the following details?

1. Device model and iOS version where the issue occurs
2. Project version (e.g., .NET 9, 10)
3. Any custom gesture recognizers or ScrollView configurations used

Once we have this information, we’ll analyze the behavior more precisely and suggest a suitable workaround or fix.

 

Regards,

Vallarasu R.

I have modified you sample to replicate the issue I am facing. Please review it. I have tested it on iPhone 17 iOS 26.0 simulator on which it is not working. But on iPhone 16 iOS 18.6 simulator, it is working fine.

I have attached the modified main page as well as the demo videos on both simulators.

Hi Simon Maystre,

We have successfully reproduced the reported issue on our end. The problem occurs when using DrawingView within a scroll view. We are currently exploring alternative approaches to resolve this at the sample level. Once we have verified the fix, we will share the details with you. We appreciate your patience until then.

Hi Simon Maystre,

 

Thank you for sharing the modified sample and the videos. We reviewed them and were able to reproduce the behavior you’re seeing:

 

Workaround To make this stable on the latest simulator, temporarily disable the native pan recognizer of the ScrollView while drawing, then re-enable it when drawing completes. This uses the built-in MAUI ScrollView (no custom control required).

 

Please let us know if this resolves the issue on your side or if you’d like us to provide a complete sample with the above changes applied.

Regards,
Natarajan R.

Hi,

Thank you for the workaround. However, I noticed that your sample uses .NET 10, while we are still on .NET 9.
That said, the issue doesn’t seem to be related to the .NET version. I found that when the signature pad is wrapped inside the sfInputLayout, the scrolling solution does not work.

To replicate the issue, please try wrapping the signature pad inside the sfInputLayout control and check the result on iOS 26.0.

Could you provide a solution for this as soon as possible?

Hi Simon Maystre,

 

Thank you for clarifying your scenario and sharing the details. We understand your requirement.

Please note that the SignaturePad control should not be wrapped inside SfTextInputLayout, as this layout only supports text-based editor controls. For more details, you can refer to the following documentation: Supported Input Views in .NET MAUI Text Input Layout | Syncfusion. 
Please let us know if you have any further questions or need assistance in the meantime, please don’t hesitate to reach out.

Hi 
Thanks for the update. 
But this was working fine on the older version of NuGet packages and stopped working when I updated to new version of Syncfusion

Hi Simon Maystre,

Thank you for reaching out to us. We noticed that you have wrapped SfSignaturePad inside SfTextInputLayout, which is not the correct usage.

Could you please share more details about what you are trying to achieve in your sample? Once we understand your requirement, we will be happy to suggest an appropriate solution.

Please note that the previous behavior you observed was not the intended or correct behavior, and we do not have plans to support this scenario in the future. As mentioned earlier, SfTextInputLayout only supports built-in input controls such as:

• SfAutoComplete
• SfComboBox
• SfNumericEntry
• SfMaskedEntry
• Entry
• Editor
  

For more details, please refer to our documentation:  Supported Input Views in .NET MAUI Text Input Layout | Syncfusion. 

Looking forward to your input so we can assist you further.

Best regards,

Tameem
