    May have encountered a bug with validation on RadMaskedTextbox with RequiredFieldValidator, where the textbox remains invalid despite a valid input being entered.

    Steps to replicate:

    - Enter a complete, valid number

    - Click outside of textbox

    - Click back into textbox and delete some numbers

    - Click outside of textbox to get the validation message

    - Now enter a complete, valid number again - still treated as invalid and error message remains displayed.

    <telerik:RadMaskedTextBox ID="tbTelephone" runat="server" Width="164px" Skin="Silk" Mask="###########" RequireCompleteText="true" />
    <asp:RequiredFieldValidator ID="rfvTelephone" runat="server" Display="Dynamic" CssClass="validation" Text="*Required" ControlToValidate="tbTelephone" />

    Hi Scott,

    I tested the provided code on my end using the latest version of the controls and it behaves correctly. See my test movie below and let me know if I'm missing something.

    Also please let me know which version of the controls you are using and verify if the issue paper in case you upgrade to the latest official release.
