i have a captcha, text boxes , combo boxes in a page.
But the client side validation of the captcha is not working.

<telerik:RadCaptcha CaptchaImage-BackgroundNoise="Medium"  CaptchaImage-TextColor="DarkSlateGray" 
                                EnableViewState="true" ProtectionMode="Captcha" CaptchaImage-TextChars="LettersAndNumbers" 
                                ID="rcapContactUs" runat="server" ErrorMessage=" The code you entered is not valid." 
                                Display="Dynamic" SetFocusOnError="True" ValidationGroup="MyContact"   
                                EnableRefreshImage="true"    
                                Font-Size="Smaller" CaptchaTextBoxCssClass="pageTextbox"   
                                CaptchaTextBoxLabelCssClass="pageLabelsHead" Font-Names="Arial"   
                                IgnoreCase="False">  
                                <captchaimage backgroundnoise="Medium" textcolor="DarkSlateGray" />

Hello,

RadCaptcha does not perform client-side validation, because of security reasons. A postback is needed for the code to be validated.
