RadComboBox methods undefined

[Avi]

Hi all

When I use the following code I get combo2 as null
var combo2 = $find('<%= rcb_DbPrefixes.ClientID %>');

When I try one of the following I get a get an object
var combo2 = $get('<%= rcb_DbPrefixes.ClientID %>'); 
var combo2 = document.getElementById('<%= rcb_DbPrefixes.ClientID %>');

However, when I try using functions such as:
var item = combo2.findItemByText(text);  
or 
combo2.get_items()

I get that those functions are undefined for the object.  When I look at the object's methods with the debugger I see many methods but non of them are the ones shown above.

What am I doing wrong?

Thanks a million,
Avi

Hello Avi,

Please try the following code:

javascript

<script language="javascript" type="text/javascript">
    var ajaxCombo;
    function GetCombo(sender, args) { ajaxCombo = sender; }
    function ShowItem() { alert(ajaxCombo.get_items().getItem(0).get_text()); }
</script>

html

<telerik:RadComboBox ID="ComboAjax" runat="server" OnClientLoad="GetCombo">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" Value="Item1" />
        <telerik:RadComboBoxItem Text="Item2" Value="Item2" />
    </Items>
</telerik:RadComboBox>
<asp:Button ID="Button1" OnClientClick="ShowItem()" runat="server" Text="Get Item" />
