    <head runat="server">
        <title>Untitled Page</title>
    </head>
    <body>
        <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager" runat="server"/>    
        <div>
            <telerik:RadTextBox runat="server" ID="textboxmemo" TextMode="MultiLine" Rows="3" MaxLength="500" Width="300px">
            </telerik:RadTextBox>    
        </div>
        </form>
    </body>
    </html>

    Hello Ricardo,

    Thank you for reporting this problem. We have just fixed it and changes will take effect in our next release or internal build. In the meantime, you can add the following Javascript code to the website as a workaround:

    if (typeof(Telerik) != "undefined" && typeof(Telerik.Web.UI.RadTextBox) != "undefined") 
    { 
        Telerik.Web.UI.RadTextBox.prototype._onTextBoxMouseWheelHandler = function (e) 
        { 
            return true; 
        } 
    } 


    I have updated your Telerik points.

    Hi Nikolas,

    You should put that Javascript code in a <script> tag in the <body> (not in the <head>), so that it is parsed after the embedded scripts in order to override them. You can alternatively add the script in an external .js file, but again, you have to register that file in the <body>.

    Nikolas, 

    This code does perfect work for me :)

    I put that Javascript code in a <script> tag in the <body> of my MasterPage.

     

    if (typeof(Telerik) != "undefined" && typeof(Telerik.Web.UI.RadTextBox) != "undefined")

     

    {

    Telerik.Web.UI.RadTextBox.prototype._onTextBoxMouseWheelHandler =

    function (e)

     

    {

     

    return true;

     

    }

    }
