When I have multiples AjaxFileUpload controls on the same page, the event fired is always the same.

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using AjaxControlToolkit;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
//Only this event is fired, and allways with id=AjaxFileUpload1 and ContextKeys=1
protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
AjaxFileUpload aj = sender as AjaxFileUpload;
string id = aj.ID;
string ContextKeys = aj.ContextKeys;
}
protected void AjaxFileUpload3_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
}
protected void AjaxFileUpload2_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
}
}
Comments: To make things worse; you cannot use the ContextKeys to identify the control as the sender within OnUploadComplete event is always the first FileUpload control on the page.
