I have a problem to open jquery popup in codebehind using asp.net

<div id="popupSharev" class="popup_block2">
              <div id="Div2" class="active">
            <div id="share-link1" class="share-link">
            
            <p>
            <a id="hide" href="#" title="Close" class="c-link"></a>
            <h3>Hi this is popup window</h3>
            <asp:Button runat="server" ID="btnUpdate" />
            </p>
            </div>
            </div>
            </div>

<a id="imgshare" href="#?w=500" class="poplight1" rel="popupSharev">
                                           <span><b>1.3K</b> SHARES</span>
                                       </a>
