combo box load on demand show nearby results

[Phillip]

How do I show the nearby results when typing a search?

If I have a list of 1, 2, 3, 4, 5 in that order in the combo box.  If I type 3 in the box it only shows me 3 as an option, but I would like it to select 3 and but show 1, 2 above it and 4, 5 below it.  This will help me because my list is about 1000 items long.  After I select the item and the page posts back showin my results the item selected is showing in the list, but I need to click there and change to different item in the drop down.  Right now I have to delete what is in the list by selecting and delete and then it shows all the items.  I would like to just be able to drop down and scroll to the next item.

Hello Phillip,

The desired functionality is not supported by the RadComboBox. Alternatively you could use the following approach:

<telerik:RadComboBox ID="RadComboBox1" runat="server" Filter="StartsWith" AutoPostBack="true" OnClientDropDownOpening="OnClientDropDownOpening">
           <Items>
               <telerik:RadComboBoxItem Text="1" runat="server" />
               <telerik:RadComboBoxItem Text="2" runat="server" />
               <telerik:RadComboBoxItem Text="3" runat="server" />
               <telerik:RadComboBoxItem Text="4" runat="server" />
               <telerik:RadComboBoxItem Text="5" runat="server" />
               <telerik:RadComboBoxItem Text="6" runat="server" />
               <telerik:RadComboBoxItem Text="7" runat="server" />
           </Items>
       </telerik:RadComboBox>

<script type="text/javascript">

          function OnClientDropDownOpening(sender, args) {

              if (sender.get_text().length > 0) {

                  sender.findItemByText(sender.get_text()).highlight();
                  sender.set_text("");
              }
          }
      </script>

With the above implementation when you open the drop-down of the combobox, the selected item will be highlighted then the text from the input will be cleared which will cause all records to be shown, so you could choose a new item.
