Hi all,

Iím very new here and I hope you can help me.

Iím using ASP.NET and I have a list box.

On page load (in the "code behind") Iím adding the value "Dani" to the list box.
==================================================
If Not Page.IsPostBack Then
ListBoxPoints.Items.Add("Dani")
End If
==================================================

Then in the client-side Iím adding the value "Ben" to the list box

==================================================
var Points_ = document.getElementById("ListBoxPoints");
var myOption = document.createElement("OPTION");
myOption.text = "Ben";
myOption.value = "Ben";
Points_.add(myOption);
==================================================

Up to here, all is good.
Now, when I click Submit and go to the server, I canít see "Ben" in there like it wasn't added to the list box.

What am I doing wrong?
Any help will be highly appreciated.
Thanks Eran

The client-side one is added after the page has been executed on the server. When you reload the page the server-side code doesn't have the 'Ben' entry yet.
