The following section of the Moving Items Between Two List Boxes online demo illustrates how moving ASPxListBox items is implemented using the ASPxClientListBox.GetSelectedItems, ASPxClientListBox.AddItem, ASPxClientListBox.RemoveItem, ASPxClientListBox.BeginUpdate and ASPxClientListBox.EndUpdate client methods.

function AddSelectedItems() {
    MoveSelectedItems(lbAvailable, lbChoosen);
...
}

function RemoveSelectedItems() {
    MoveSelectedItems(lbChoosen, lbAvailable);
...
}
function MoveSelectedItems(srcListBox, dstListBox) {
    srcListBox.BeginUpdate();
    dstListBox.BeginUpdate();
    var items = srcListBox.GetSelectedItems();
    for(var i = items.length - 1; i >= 0; i = i - 1) {
        dstListBox.AddItem(items[i].text, items[i].value);
        srcListBox.RemoveItem(items[i].index);
    }
    srcListBox.EndUpdate();
    dstListBox.EndUpdate();
}
