PasswordStrengthSettings not supported

[Kyle]

I'm trying to use the PasswordStrengthSettings attributes of the RadTextBox for the first time, but Visual Studio keeps telling me they're not supported. Here's the code in question:

<telerik:RadTextBox runat="server" ID="txtNewPassword" TextMode="Password">
    <PasswordStrengthSettings showindicator="true" minimumnumericcharacters="1" minimumsymbolcharacters="0"
             textstrengthdescriptionstyles="RedText;RedText;GreenText;GreenText;BlueText;BlueText;" PreferredPasswordLength="8"/>
</telerik:RadTextBox>

And here's the assembly declaration at the top of the page (in case it's a versioning issue): 

<%@ Register Assembly="Telerik.Web.UI, Version=2009.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
    Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

The solution fails to build as well. Any help is greatly appreciated.

Hi Kyle,

PasswordStrengthSettings feature is not offered in 2009.3.1314.35 version of telerik. From Q2 2011, RadTextBox control offers a PasswordStrengthSettings feature. Please update to latest version.

Hope this helps.

Thanks,
Shinu.
