    I'm using popup editing mode for my grid model and there is one checkbox which is required. I'm encountering an issue that the checkbox doesn't seem to be validated on blur. After I checked the box, the validation message is not getting removed. Other text fields and drop down fields are working fine. How would I resolve this issue?

    Hello, Van,

    I tested with a checkbox in one of our editable grids by adding a required validation and that seems to work as prescribed. Can you take a look at this Dojo and let me know in case you see any differences with your implementation:

    Look forward to hearing back from you.

    Thank you for your input! I eventually found out the issue when looking at the value attribute of <input />. It was empty originally (value="") instead of true or false. That is because the default value of the checkbox is set to empty string.

    Hi Van,

    I am glad to hear that you have managed to resolve the issue on your own! Indeed, having the input elements with a value different than a boolean might cause unexpected behavior. This is due to the fact that the validator checks the type and value simultaneously.

    If you encounter any other obstacles, do let me know. I will be happy to assist.


    Kind regards,
