I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.
[Code].....
I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.

I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind.

I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.

How can I enable/disable Next/Prev buttons within a specific step?.

I am moving an app from Silverlight back to ASP.NET. (Don't ask!) I really liked the ability to highlight ListBox items as the user moved the mouse over the items. I have been Bing'ing all morning and cannot seem to find any way to do this in ASP.NET with an ASP:ListBox. I tried setting the onmouseover event for the list items themselves. But that did nothing.
[Code]....
I then tried setting onmouseover event for the list itself. I can get the event, but I don't know how to determine which item I am over. I only seem to have the selectedIndex. If I am just moving the mouse, I have no selectedIndex.
When I have multiple entries with the same id in a list box the selected index is always the first instance of the item. How do I get around this without modifying the id of the items in my list box so they are unique?
