How to use mask in ext.net mobile textfield?
In the version for webforms I use InputMask.
How would it be in the mobile version?

Ex.: 
<ext:TextField ID="txtPlaca" Padding="1" runat="server" Width="130" FieldLabel="Placa" Name="Placa" LabelAlign="Top">
     <Plugins>                                                        
        <ext:InputMask runat="server" Mask="999-9999" />                                        
     </Plugins>                                                          
</ext:TextField>
