Suppose that id of the ">>" button is btnLoad and its click event handler is btnLoad_Click

lst1 is First List box and lst2 is Second list box:

    protected void btnLoad_Click(object sender, EventArgs e)
    {
        lst1.GetSelectedIndices();
        foreach (int item in lst1.GetSelectedIndices())
        {
            lst2.Items.Add(lst1.Items[item]);    
        }
    }

be sure that both list boxes should have 

SelectionMode="Multiple"

or 

         protected void btnLoad_Click(object sender, EventArgs e)
     {
        lst1.GetSelectedIndices();
        foreach (int item in lst1.GetSelectedIndices())
        {
            var tempItem = lst1.Items[item];
            tempItem.Selected = false;
            lst2.Items.Add(tempItem);    
        }
     }

with 

SelectionMode="Single"

hope it helps
