I have a web form in asp.net contains a RadAsyncfileupload and a RadBinaryImage inside an Asp Update Panel like following 

<body>
    <form id="form1" runat="server">
     <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>

    <asp:UpdatePanel runat="server">

<ContentTemplate>

    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server">
    </telerik:RadAsyncUpload>
    <telerik:RadBinaryImage ID ="RadBinaryImage1" runat ="server" Width= "100px" Height="100px"/>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>

in code behind 

  protected void RadAsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
        {
            if (RadAsyncUpload1.UploadedFiles.Count == 1)
            {
                byte[] image;
                long fileLength = RadAsyncUpload1.UploadedFiles[0].InputStream.Length;
                image = new byte[fileLength];
                RadAsyncUpload1.UploadedFiles[0].InputStream.Read(image, 0, image.Length);
                RadBinaryImage1.DataValue = image;

            }

        }

but in runtime program controller does not fire RadAsyncUpload1_FileUploaded event I have searched the Telerik forum and found that I should do something to script manager but I need some help on how to do it the reason is that in order to fire this event whole page should post back anyway some scripts can help me or any other ways! mention that I need byte array of the image to save it in DB. Thanks in advance Saeed Soleimanifar

I just added the same functionality by using this , if you find any problem let me know... OR Here is the part that does the magic

Page Source :

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

    <script type="text/javascript">


        function updatePictureAndInfo() {

            __doPostBack('btnImgUpload', 'RadButton1Args');

        }

    </script>

</telerik:RadScriptBlock>

<telerik:RadBinaryImage runat="server" ID="imgBinaryPhoto" ImageUrl="~/Images/default-profile-pic.png"
                Width="100px" Height="100px" ResizeMode="Fit" AlternateText="No picture available"
                CssClass="preview"></telerik:RadBinaryImage>
            <br />
            <telerik:RadAsyncUpload ID="upldPhoto" runat="server" AllowedFileExtensions=".jpg,.png,.gif,jpeg,.tiff"
               MaxFileInputsCount="1" MultipleFileSelection="Disabled">
            </telerik:RadAsyncUpload>
            <asp:Button ID="btnImgUpload" runat="server" Text="Upload" CssClass="button" OnClientClick="updatePictureAndInfo(); return false;" />

Code Behind:

Protected Sub FileUploaded() Handles upldPhoto.FileUploaded

        Dim bitmapImage As Bitmap = ResizeImage(upldPhoto.UploadedFiles(0).InputStream)
        Dim stream As System.IO.MemoryStream = New System.IO.MemoryStream()
        bitmapImage.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp)
        imgBinaryPhoto.DataValue = stream.ToArray()

    End Sub
