                base.OnPreRender(e);
                if (UploadAttachments1.Items.Count>= 3)
                {
                    Uploader1Insert.Visible = false;
                    UploadAttachments1.InsertButton.Enabled = false;
                }
                else

    Hi steveyuan,
     
    If you use property InsertButtonID, please set this control directly
