Multiple instance of ASP.Net AjaxFileUpload not working in same page

Hi everyone,

i have to use two different Ajaxfileupload controls in a page .But when i upload file through second control the second event doesnot get fired(UploadComplete) everytime first event is fired.

<asp:AjaxFileUpload ID="AjaxFileUpload1" runat="server" 
                 OnClientUploadComplete="onClientUploadComplete"
             MaximumNumberOfFiles="10"
            AllowedFileTypes="jpg,jpeg"  OnUploadComplete="AjaxFileUpload1_UploadComplete" />

<asp:AjaxFileUpload ID="AjaxFileUpload2" runat="server" 
                 OnClientUploadComplete="onClientUploadComplete1"
             MaximumNumberOfFiles="10"
            AllowedFileTypes="jpg,jpeg"  OnUploadComplete="AjaxFileUpload2_UploadComplete" />

protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs file)
    {
        if (file.ContentType.Contains("jpg") || file.ContentType.Contains("gif")
           || file.ContentType.Contains("png") || file.ContentType.Contains("jpeg"))
        {
            
            string filePath = @"C:\Desktop\\test\" + file.FileName;
            AjaxFileUpload1.SaveAs(filePath);
        }

       }
protected void AjaxFileUpload2_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs file)
    {
        if (file.ContentType.Contains("jpg") || file.ContentType.Contains("gif")
           || file.ContentType.Contains("png") || file.ContentType.Contains("jpeg"))
        {
            string filePath = @"C:\Desktop\test1\" + file.FileName;
            AjaxFileUpload2.SaveAs(filePath);
        }

    }
