    Hi is there a concept of requiredfieldvalidators in silverlight, if not how are people handling situations which require a textbox to be filled in before a button is clicked, i tried the IDataErrorInfo method, however this does not work when the textbox has not been tabbed into.

    Hi Peter,

    You can try working with DataAnnotations and set Required attribute to the properties you want. Please take a look at the following articles for a reference:
    1. Using DataAnnotations to Customize Data Classes.
    2. Validation.

    Let me know in case you need any further assistance.
