    Hello folks,
    I have requirement like these.I have rad-window inside I have following code .

    <telerik:RadWindow ID="rdwndwPreviewCheck" VisibleOnPageLoad="false" Title="Check Preview">
                <asp:Image ID="chkImage1" runat="server" ImageUrl="~/CheckPreview.aspx" />
                <br />
                <br />
                <table style="width: 100%;">
                    <tr align="center">
                        <td style="width: 580px;">
                            <telerik:RadButton ID="rdPrint" runat="server" Text="  Print"   Style="position: relative;
                                left: 90px;"  OnClick="print"    >
                                <Icon SecondaryIconCssClass="rbPrint" SecondaryIconRight="4" SecondaryIconTop="4" />
                            <telerik:RadButton ID="CloseRadPrintWindow" runat="server" Text="Close" OnClientClicked="closeMyRadWindow"
                                Style="position: relative; left: -185px;">

    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[]
    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 ='', '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 + '">');
                    return false;
    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  and this help article
