ListBox Item Width

[Farooq]

I have a radlistbox and the items are being inserted programmatically, how do I expand the width of an item so multiple items won't show on a single line as they are showing as of now.

currently items are being inserted to listbox in c# like :

rlbAssigned.Items.Add(new RadListBoxItem(rlbAvailable.Items[rlbAvailable.SelectedIndex].Text, rlbAvailable.Items[rlbAvailable.SelectedIndex].Value));

and the listbox is declared as:

<telerik:RadListBox ID="rlbAvailable" runat="server" Height="320px" Width="200px">                                         </telerik:RadListBox>

I figured it out since it has Ul and li I resolved it using css like so:   

.RadListBox ul li      

   {

     float: left !important;     

     width: 170px;

   }

I would be glad if someone comes up with a another solution.
