Image is not displayed in a Modal Pop Window using javascript and asp.net -


basically, trying develop aspx page user able upload image, display in modal pop window , crop if required.

if display image outside of pop window works fine, if try display inside of pop window image not displayed. however, have noticed if keep image there , remove <asp:image id="imgcrop" javascript below, image displayed , off course not allow me crop it.

here javacripts use display modal popwindow , set crop settings: 

            <head runat="server">                 <title>crop image</title>                 <link href="styles/jquery.jcrop.css" rel="stylesheet" type="text/css" />                 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>                 <script type="text/javascript" src="scripts/jquery.jcrop.js"></script>                   <script type="text/javascript" src="scripts/jquery.helper.js" ></script>                 <link href="styles/style.css" rel="stylesheet" type="text/css" />                  <script type="text/javascript">                     jquery(document).ready(function () {                         jquery('#imgcrop').jcrop({                             onselect: storecoords                         });                     });                      function storecoords(c) {                         jquery('#x').val(c.x);                         jquery('#y').val(c.y);                         jquery('#w').val(c.w);                         jquery('#h').val(c.h);                     };                 </script>             </head>

here definition of modal pop window , want see image cropped in <asp:image id="imgcrop"

            <input class="button_popup" id="btnshowmodaldiv" onclick="$('#divsimplepopup').showmodal(); return false;" type="submit" value="show modal div"/>                  <div id="divsimplepopup" class="popup" style="display: none; width: 350px;">                     <div class="container">                         <div class="header">                             <span id="lblpopupheader" class="msg">simple popup header</span>                             <a id="btnclosepopup" class="close" onclick="$('#divsimplepopup').hidemodal(); return false;" ></a>                         </div>                         <div>                             <div class="body" style="height: 100px; overflow: auto;">                              <asp:panel id="pnlcrop" runat="server" visible="false">                                 <asp:image id="imgcrop" runat="server" />                                 <br />                                 <asp:hiddenfield id="x" runat="server" />                                 <asp:hiddenfield id="y" runat="server" />                                 <asp:hiddenfield id="w" runat="server" />                                 <asp:hiddenfield id="h" runat="server" />                                 <asp:button id="btncrop" runat="server" text="crop" onclick="btncrop_click" />                            </asp:panel>                                 </div>                             <div class="footer">                                 <input class="button_popup" id="btnok" style="width: 40px;" type="submit" value="ok"/>                                 <input class="button_popup" id="btncancel" onclick="$('#divsimplepopup').hidemodal(); return false;" type="submit" value="cancel"/>                             </div>                         </div>                     </div>                 </div>

does has hint?

<asp:image id="imgcrop" runat="server" />

your image have runat="server" may have different id when rendered.

so need have following in page.

jquery(document).ready(function ()   {    jquery('#<%= imgcrop.clientid %>').jcrop({      onselect: storecoords    });  });

apart you've visible="false" on panel shown in below code:

  <asp:panel id="pnlcrop" runat="server" visible="false">

so whole panel won't rendered , jquery code won't work. rather use style="display:none", panel rendered , image , plugin work.
