  Hi All,
  
  I am using telerik ComboBox, with label enabled, Now i am in a situation where i need to hide dropdown and just display a friendly message in place of the dropdown, i still need to have label of the filter all the time.
  
  What i have tried is using DropDownCssClass, but it is not able to hide complete dropdown.
  
  Is there any way to hide complete dropdown and display friendly message.

  I also Tried using Empty message field, but i don't figure out a way to hide drop down and just make the empty message look like a label.

  Hello,
  
  I am not quite sure about your scenario.
  
  If you want to hide the dropdown arrow set  ShowToggleImage property to false.
  RadComboBox1.ShowToggleImage = false;
  
  Or if you want to prevent the DropDown from opening, then you can use OnClientDropDownOpening client-side event which occurs before the drop-down list opens and cancel the event from there
  .
  aspx:
  

  <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientDropDownOpening="OnClientDropDownOpening"  ShowToggleImage="false"  AllowCustomText="true">

  </telerik:RadComboBox>

  
  Javascript:
  

  function OnClientDropDownOpening(Sender, args)

    {

        args.set_cancel(true);

    }

  
  Thanks,
  Shinu.

  Hi Shinu,
  
  Thanks for ur reply, but what i am trying to do here is 
  when there are no values in the filter i need to hide the filter completely and display a friendly message in place of the filter,
  as you said i can hide the toggle image, but i cannot hide the input box around the empty message. user should basically feel like there is a label and no dropdown over there(When no values in filter)

  Hello,
  
  Try the following code snippet in the OnClientDropDownOpening.
  
  javascript:
  

  function OnClientDropDownOpening(Sender, args)

     {   

         if (Sender.get_items().get_count() == 0) {

             args.set_cancel(true);

             Sender.clearSelection();

             Sender.set_emptyMessage("No Item!!");

         }

     }

  
  Thanks,
  Shinu.
