How to check if signature is empty?

[Pierre-Christophe DUS]

Hello, 

I would like to know if there is a way to know if a signature is empty, cause I would like to enable a "save" button only if the signature is not empty.

I've seen that the question has already been posted for Flutter, but I didn't found a similar one for Xamarin.Forms.

I've tried to manage this with the ImageSource field of the signature control, but it's not a perfect solution: if the user has started to draw, and clean the signature of the SfSignaturePad, the ImageSource field is not null.

Would you have a better suggestion?

Thank you!

Hi Pierre Chirstophe, 

Greetings from Syncfusion.  

Currently, we don’t have direct support to achieve your requirement other than using ImageSource filed. So, we have considered “Drawing start and ene event support for signaturepad” as a feature and already logged this as a feature request, and you can track the status of this feature implement through below link,

When we end drawing in the SfSignaturePad, the above event is triggered. In this case you can enable the save to achieve your requirement. 

This feature will be available in our upcoming Volume 2 main release, which is scheduled to be released at the end of June 2021. Until then, we appreciate your patience.
