    Hello Yugandhar,

    Unfortunately, I am unable to see the XAML that you had pasted, but I have put together a sample project in which the IDataErrorInfo interface is implemented with the XamTextEditor.

    In order to show the error message in a tooltip, I would recommend binding your Tooltip property using a RelativeSource Self binding to the attached Validation.Errors property on the XamTextEditor. You can index into this collection, and then show the ErrorContent of your error, which will be the string you are returning. The binding for this could look like the following:

    Tooltip="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"

    I have attached a sample project to demonstrate the above. I hope this helps.

    Please let me know if you have any other questions or concerns on this matter.

    Sincerely,
