How can I implement the multi look up select list items functionality in SharePoint using asp.net C#?
Please help me with some code, I am using two list boxes and have added a add remove button on the page, but I have set postback true on listbox item.
So the page posts back once I select any item. I do not want this to happen as I just want to move items from one listbox control to another.
In short I just want a nice solution to implement the below functionality in an asp.net c# page.
