I found the RadComboBox (RenderMode=Natvie) will render as block (not inline in other modes).
How could I let it display as inline?
<telerik:RadComboBox ID="RadComboBox1" runat="server" RenderMode="Native"> <Items> <telerik:RadComboBoxItem Text="A" Value="A"/> <telerik:RadComboBoxItem Text="B" Value="B"/> </Items></telerik:RadComboBox>
