    Hi all

     I have a  RadComboBox in and i have used  AllowCustomText="true" . so that way if user does not want to select the pre enter value he/she can enter his own value in radcombo box . but when a user can enter any element such like <b>,<br> mean any html tag and press enter button for submitting data it show error . i have create a java script code that removed <> before any text on blur event and it working fine to me but when i click to save the document it show error page . How can i solve this problem ?

    Hi Sushobhit,

    The reason you have faced such an exception is that ASP.NET prevents from processing unencoded HTML content submitted to the server. Here you could find a help article, where you could observe how to disable this restriction and eventually apply your own custom validation.

    All the best,

    Hi Sushobhith,

    Try setting the following in web.config to allow html content in input.

    <system.web >
        <httpRuntime requestValidationMode="2.0" />
    </system.web >

    And you can remove html tags in javascript as follows.

    <script type="text/javascript">
    function OnClientSelectedIndexChanging(sender, args)
       var text = sender.get_text();
       text = text.replace(/</g, "");
       text = text.replace(/>/g, "");

    Hope this helps.
