javascript function: function fun(id) { var obj = document.getElementById(id); var cnt = obj.options.length; var checked = 0; for (var i = 0; i < cnt; i++) { if (obj.options[i].selected) checked++; } if (checked > 5) { alert('more than 5 selection'); obj.focus(); } } ################################### Server side: ListBox1.Attributes.Add("onblur", "fun('" + ListBox1.ClientID+ "');");
