[Shahid Abbas]

Is there any way to validate signature pad signed or not

Hi Shahid,

Greetings from Syncfusion.

We have analyzed your query and currently we don't have direct support. We can workaround to achieve your requirement by checking ImageSource property of SfSignaturePad control as like below code snippet.

XAML:

 

<signature:SfSignaturePad   x:Name="signature"  

                                      HeightRequest="250"/>  

C#: 

  void Button_Clicked(System.Object sender, System.EventArgs e)  

        {  

            signature.Save();  

  

            if (signature.ImageSource != null)  

            {  

                DisplayAlert("Signed or not", "You have signed", "Ok");  

            }  

            else  

            {  

                DisplayAlert("Signed or not", "You have not signed", "Ok");  

            }  

        }  

We have created sample based on this and please find the sample from below.
