Hi Pankaj,

Please have a look into the following sample code snippet which works fine at my end.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnablePageHeadUpdate="false">
</telerik:RadAjaxManager>
<telerik:RadWindow ID="Radwindow1" runat="server" VisibleOnPageLoad="true">
    <ContentTemplate>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <telerik:RadAsyncUpload ID="AsyncUpload1" runat="server"    OnClientFilesUploaded="OnClientFilesUploaded" OnFileUploaded="AsyncUpload1_FileUploaded"    AllowedFileExtensions="jpg,png,gif,bmp" />
                <telerik:RadImageEditor ID="RadImageEditor1" runat="server" Width="680"   Height="450"  ImageUrl="~/Images/350chev_conrod265_76.jpg" OnImageLoading="RadImageEditor1_ImageLoading">
               </telerik:RadImageEditor>
            </ContentTemplate>
        </asp:UpdatePanel>
    </ContentTemplate>
</telerik:RadWindow>

JavaScript:

<script type="text/javascript">
    function OnClientFilesUploaded(sender, args) {
        $find('<%=RadAjaxManager1.ClientID %>').ajaxRequest();
    }
</script>

C#:

protected void AsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
{
    RadImageEditor1.ResetChanges();
    Context.Cache.Remove(Session.SessionID + "UploadedFile");
    using (Stream stream = e.File.InputStream)
    {
        byte[] imgData = new byte[stream.Length];
        stream.Read(imgData, 0, imgData.Length);
        MemoryStream ms = new MemoryStream();
        ms.Write(imgData, 0, imgData.Length);
        Context.Cache.Insert(Session.SessionID + "UploadedFile", ms, null, DateTime.Now.AddMinutes(20), TimeSpan.Zero);
    }
}
protected void RadImageEditor1_ImageLoading(object sender, ImageEditorLoadingEventArgs args)
{
    if (!Object.Equals(Context.Cache.Get(Session.SessionID + "UploadedFile"), null))
    {
        using (EditableImage image = new EditableImage((MemoryStream)Context.Cache.Get(Session.SessionID + "UploadedFile")))
        {
            args.Image = image.Clone();
            args.Cancel = true;
        }
    }
}

Thanks,
Princy.
