How to count listbox items in codebehind when i add item using Javascript!

[Chetan visodiya]

Hi! In facts, my problem is to access the info in the server side! If i use ListBox.Items... It is not working but I really have two rows in my listbox... Look this: This is my javascript code: First i select the item in listbox1 then click on add button so add seleccted item into listbox2 and remove selected item from listbox1 using javascript. function fctAjoutAssigne() { var mylist = document.getElementById("ListBox1") var mylist2 = document.getElementById("ListBox2") mylist2.options[mylist2.length]= new Option(mylist.options[mylist.selectedIndex].text,mylist.options[mylist.selectedIndex].value); mylist.remove(mylist.selectedIndex) } and at last i click on save button. code of save button is : For i = 0 To ListBox2.Items.Count - 1 strAssignation &= ListBox2.Items(i).Value & "," strNomAssigne &= ListBox2.Items(i).Text & ";" Next But ListBox2.Items.Count = 0 even If I have two items in my list... Amazing... if you know then tell me how to fix this. chetan patel

Hi man. Why don't you use code behind to populate your ListBox2 instead of JavaScript? I'm not sure how your code works but I think what happens is: 1. When you add new items with JavaScript it works no problem 2. When you clisk Save button it submits the page and you are loosing your valuse in the ListBox2. Seems like Posting is your problem.

Sounds like you need some AJAX!
