I am using Radcombox control on my asp.net page, but combobox doesn't drop at all. I can see the items are there, but it doesn't expand. Please have a look at the code and attached image as well.
                                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager><telerik:RadComboBox ID="RadComboBox1" runat="server" Height="240" Width="150" Skin="Forest"               Label="Natural numbers">    <Items>        <telerik:RadComboBoxItem Value="1" Text="1" />        <telerik:RadComboBoxItem Value="2" Text="2" />        <telerik:RadComboBoxItem Value="3" Text="3" />        <telerik:RadComboBoxItem Value="4" Text="4" />        <telerik:RadComboBoxItem Value="5" Text="5" />        <telerik:RadComboBoxItem Value="6" Text="6" />        <telerik:RadComboBoxItem Value="7" Text="7" />        <telerik:RadComboBoxItem Value="8" Text="8" />        <telerik:RadComboBoxItem Value="9" Text="9" />        <telerik:RadComboBoxItem Value="10" Text="10" />    </Items></telerik:RadComboBox>
