<script runat="server">
void InsertMsg(string msg)
{
ListBoxEvents.Items.Insert(0, msg);
ListBoxEvents.SelectedIndex = 0;
}
protected void UploadAttachments1_AttachmentAdded(object sender, AttachmentItemEventArgs args)
{
InsertMsg("Added.." + args.Item.FileName);
}
protected void UploadAttachments1_FileValidating(object sender, UploaderEventArgs args)
{
if (args.FileSize == 0)
{
throw (new Exception("Please do not upload empty file !"));
}
}
</script>
