Multi ajax file upload based on dropdown selection asp.net

Question

Based on dropdown i'm getting value and need to use for ajax file upload, now the problem is that i'm getting value properly, i'm using two ajax file upload(ajaxUpload1_OnUploadComplete & ajaxUpload2_OnUploadComplete), whenever i click the upload control for uploading files from the both the control goes to one upload method(ajaxUpload1_OnUploadComplete) only for uploading files. I need a solution for this. Thanks in advance.

In .cs

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {

        Session["Value"] = DropDownList1.SelectedItem.Text;
    }

protected void ajaxUpload1_OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
    {
        String value = Session["Value"].ToString();
    }

 protected void ajaxUpload2_OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
    {
        String value1 = Session["Value"].ToString();
    }

In .aspx

 <asp:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="jpg,jpeg" MaximumNumberOfFiles="10" ThrobberID="1" ContextKeys="1"  OnUploadComplete="ajaxUpload1_OnUploadComplete" runat="server"/>

 <asp:AjaxFileUpload ID="AjaxFileUpload2" AllowedFileTypes="jpg,jpeg"  ThrobberID="2"  MaximumNumberOfFiles="10" ContextKeys="2" OnUploadComplete="ajaxUpload2_OnUploadComplete" runat="server" />

@YuriyRozhovetskiy I already gone through with that, and found cannot have one or more ajaxfileupload in same page. So i left this concept, anyhow thank you for your kind help. — Jaya shanmuga pandian

I think it a bug in the AjaxFileUpload I asked about this before and never got any reply except work a workaround here is the solution for this.

private string ContextKey = "";
public AjaxFileUpload()
            : base(true, HtmlTextWriterTag.Div)
        {
            if (HttpContext.Current.Items["lastAjaxFileUploadContextKey"] == null)
            {
                HttpContext.Current.Items["lastAjaxFileUploadContextKey"] = 1;
            }
            else
            {
                HttpContext.Current.Items["lastAjaxFileUploadContextKey"] = (int)HttpContext.Current.Items["lastAjaxFileUploadContextKey"] + 1;
            }

            ContextKey = HttpContext.Current.Items["lastAjaxFileUploadContextKey"].ToString();
        }

I was also faced the same problem, so just I removed the second Ajaxfileupload control , and I upload the files based on the dropdown selected value. I am just using single fileupload control, and add the Dropdownlist selectedindexchanged event, in that you set the path accordinglny.
