Signature Pad Prevent Swiping

[Finlay]

Hello Syncfusion

Is it possible to set focus to a signature pad in xamarin.forms to prevent vertical scrolling within a scroll view, and pulling out the side bar.

Currently I have to have the control on a modal page by itself as it is impossible to use when inside of a scroll view is there a way to prevent that behaviour.

Thanks

Hi Sakthivel

I note v18.4.0.34 was released 18 hours ago, but it doesn't appear to have the fix according to the release notes. Is that just missing, should I download this version to fix this problem in iOS, or is there another release coming with this fix?

Thanks

Matt

Hello Team,

I am facing the same issue in MAUi. can we prevent scrolling while using signature o

[AhamedAliNishad JahirHussain]

Hi Anurag,

Upon further investigation, we have found that in iOS, there is an issue within the framework level causing the signature pad touch to be passed to the parent (scrollview). As a result, when attempting to write a signature in the signature pad on iOS, scrolling occurs, hindering the writing process. To address this, we have implemented a workaround at the sample level. Specifically, we change the scrollview orientation to "neither" when the draw operation starts and revert it to "vertical" when the draw is completed. The provided code snippet illustrates this solution. We have included the sample for your reference. Kindly review the attached sample and let us know the details.

Code Snippet :

Mainpage.xaml.cs

 

        private void signaturePad_DrawStarted(object sender, System.ComponentModel.CancelEventArgs e)

        {

            scrollView.Orientation = ScrollOrientation.Neither;

        }

 

        private void signaturePad_DrawCompleted(object sender, System.EventArgs e)

        {

            scrollView.Orientation = ScrollOrientation.Vertical;

        }

Regards,

Ahamed Ali Nishad.
