    I want the error tool tip on masked text similar to normal WPF textbox. Please find attached images.
    I also want the border of the masked input text to be red when an invalid number given as input. 
    Could you help me to achieve this? 
    I am not sure whether this request raised by anyone but i couldn't find the solution in any of the threads.
    Let me know if you need more information on this.

    Hello Vivek,

    The RadMaskedInput controls have a default ValidationTemplate which can be customized to better fit in your application design. This template is applied through the Validation.ErrorTemplate attached property:
    <telerik:RadMaskedNumericInput x:Name="radMaskedNumericInput"
        ErrorMessage="{Binding Path=Text,
        Validation.ErrorTemplate="{StaticResource TextBoxErrorTemplate}"
        Value="{Binding Path=DoubleValue,
                        ValidatesOnExceptions=True}" />

    I attached a sample solution demonstrating how to customize the ErrorTemplate of the MaskedNumericInput control to display only a Red border around the control. You can further customize this template to better fit your needs.

    Please let us know if you need further assistance.

    Kind regards,
