Error tool tip on masked input textbox similar to WPF textbox

[Vivek]

Hi, 

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.

Thanks,
Vivek

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"
    AllowInvalidValues="True"
    ErrorMessage="{Binding Path=Text,
                            ElementName=customErrorMessage}"
    Validation.ErrorTemplate="{StaticResource TextBoxErrorTemplate}"
    Value="{Binding Path=DoubleValue,
                    Mode=TwoWay,
                    NotifyOnValidationError=True,
                    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.
