<telerik:RadMaskedTextInput x:Name="rmeSolicitationNumber" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="19,39,0,0" Width="200" Mask="SPAAAA-AA-A-AAAA" Text="{Binding SolicitationNumber, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnNotifyDataErrors=False, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}" Style="{StaticResource RadMaskedTextBoxStyle}" SelectionOnFocus="SelectAll" TextMode="MaskedText" InputBehavior="Replace" />The display of the value coming back from the database is the issue. Please help me see what I'm doing wrong.
Thanks!

Hi Mike,
Please let me first make a quick clarification - you should consider the Text property as only a getter, setting or binding the Text won't change the Value property. Text is just the string you see as a combination of the properties Value, Placeholder, TextMode, Mask. So the preferred approach is to bind the Value property only and add the dashes manually when saving into the db / remove when loading from Db (this could be performed in Converter). It is also expected that the string "SP123456R7890" will be inserted from left to the right on the available positions marked with the mask symbol "A". "A" allows both numeric and alphabetic symbols. If the requirement is to use only digits for these positions, you can consider using Mask="SP####-##-#-####". Please let us know if this is what you needed.

Thanks for the reply. Would it be possible to add a boolean or some other attribute which would allow the Value property to get the literals of the mask? I believe this is the way the old MaskedTextbox worked, and this behavior is preferable to us. Also to be able to set a value and have the control overwrite the mask as well. Meaning if I bring back SP123456R7890 from the database, the control would realize SP is in the mask so the control would display correctly as opposed to doubling the "SP". Again I believe this is the way the old MaskedTextBox worked.
Thanks.
Thanks.

Hello Mike,
The Value property is designed to contain what you type or pass but without the Mask symbols. We added the Text property in the MaskedInput controls to separate this scenarios and to have a property which contains the Mask symbols. Yes, this is different than the old MaskedTextBox's behavior but makes the internal logic simpler and easy to maintain. Please have in mind that the old control used to have plenty of bugs related to databinding and did not support null values. To support mask symbols in the Value, this would require too much code for something that can be easily solved with Converters on an application level.
However, your requirement is similar to the following feature request and you can vote for it in order to increase its development priority.
