Ok, if button is inside update panel i'm assuming your page is not posting back? if so, then why don't you resolve this using javascript/jQuery on client-side?

ASP.NET

<asp:button id="btnId" runat="server" text="Click ME" onclick="btnId_OnClick" onclientclick="HideValidationSummary( $('#ValidationSummary1') );" xmlns:asp="#unknown"></asp:button>

and your jQuery function:

JavaScript

function HideValidationSummary( summaryControl )
{
    $( summaryControl ).hide( );
}

or if you want to use javascript not jQuery

ASP.NET

<asp:button id="btnId" runat="server" text="Click ME" onclick="btnId_OnClick" onclientclick="HideValidationSummary( 'ValidationSummary1' );" xmlns:asp="#unknown"></asp:button>

and your javascript function:

JavaScript

function HideValidationSummary( summaryControl )
{
    document.getElementById( summaryControl ).style.display = 'none';
}

Good luck,
Morgs
