MaskedDateTimeInput Validation

[vk]

Hello,
I'm using RIA services and CustomValidation attribute for some fields of my business object.
There are a couple of datetime fields on a DataForm which I would like to bind to a MaskedDateTimeInput, but there are some issues regarding to validation. If I use MaskedTextBox instead of MaskedDateTimeInput the first control behaves as expected...
I have attached some screenshots to show what I mean.
Problem 1: if I enter a datetime value that does not pass validation both controls go into invalid state but the dataform's field bound to MaskedDateTimeInput doesn't get red.
Problem 2: If I tab out of MaskedDateTimeInput while it is in invalid state the control shows the value that was before the change. I expected it to show the new value like the MaskedTextBox does...

     <!-- Start date -->
 <toolkit:DataField Label="Start date" >
    <telerik:RadMaskedDateTimeInput Value="{Binding DateStarted, Mode=TwoWay}" Mask="g" />
 </toolkit:DataField>

 <!-- Finish date-->
 <toolkit:DataField Label="Finish date">
     <telerik:RadMaskedTextBox Value="{Binding DateFinished, Mode=TwoWay}" Mask="g"  MaskType="DateTime" />
 </toolkit:DataField>

Hi Valentine,

The behavior you have come up with is expected by design: the RadMaskedDateTimeInput does not update its current value if the validation does not pass. However, we logged a feature request in our PITS where you are able to vote for in order to increase its development priority. 
Feel free to ask if you need further assistance.
