                            Style="position: relative; left: -185px;">
                        </telerik:RadButton>
                    </td>
                </tr>
            </table>
        </ContentTemplate>
    </telerik:RadWindow>


I want to access the  image content  inside the rad-window....through code behind technique  and  I need to assign  that Image  to  some other image .. using the  code behind technique ..after that I want to convert the Image into Byte[] ...here
the image url is not a static one and it is dynamic based on requesting the page we getting some Image .jpeg from that page.
      <script type="text/javascript">
            function printIt() {
                var win = window.open('', 'popup', 'location=1,status=1,scrollbars=1,width=800,height=600');
                if (win) {
                    var imageControl = document.getElementById('<%=chkImage1.ClientID%>').src;
                    win.document.write('<img src="' + imageControl + '">');
                    win.document.close();
                    win.focus();
                    win.print();
                }
                return false;
            }
        </script>
the above code  , I  used to  Display Image in the  ..rad-window..But ..same image I want to access code code behind technique and also I need to convert to Byte[] stream.

Hi Sairam,

The controls from the RadWindow's ContentTemplate are available directly in the code-behind from the page;s class, as can be seen by examining this demo's code  http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultcs.aspx  and this help article http://www.telerik.com/help/aspnet-ajax/window-controls-container.html.
