Hi Laerte,
Greetings from Syncfusion.
We would like to inform that, the Masked text box is an advanced version of the Entry control that restricts your input to certain types of characters, text, and numbers using a mask pattern. If you want to validate the entered value while lost focus, then you need to change the ValidationMode property of SfMaskedEdit as per the below code snippet.
[XAML]:
<maskedEdit:SfMaskedEdit Watermark="000-0000000"
ValidationMode="LostFocus"
Mask="000-0000000"
/> |
Please find the sample from the below link.
If your requirement is different from this, please provide us more information and use-case scenario of your application. This would be helpful for us to give better solution.
Regards,
Vignesh.
