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" />

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();
        }
