problem i have is that, the validation summary message(alert) is displayed twice. I cannot figure out the reason.

Please help. Here is the code

function validate() //javascript function
{
    if (typeof(Page_ClientValidate) == 'function') 
    {
        var isPageValid = Page_ClientValidate();
        if(isPageValid)
        {
        }
    }
}

<asp:Button ID="btn1" runat="server" OnClientClick="validate()" Text="button"
                    ValidationGroup="ContactGroup" />

<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="List" 
                    ShowMessageBox="true" ShowSummary="false" ValidationGroup="ContactGroup" />

just return false from the function and change the OnClientClick as shown below:

<asp:Button ID="btn1" runat="server" OnClientClick="return validate();" Text="button" 
                        ValidationGroup="ContactGroup" /> 

        function validate() //javascript function   
        {   
            if (typeof(Page_ClientValidate) == 'function')    
            {   
                var isPageValid = Page_ClientValidate();   
                if(isPageValid)   
                {   
                }   
            }   
        return false;

}
