Error: Combo client instance inside RadToolBar

[Runat="Server"]

Please show me how to find combobox with JavaScript inside other rad control! 

This is my code (not worked!):

function RadControls_Load(menu, args)
{
      var combo1 = $find("<%=RadComboBox1.ClientID %>");
      var combo2 = $find("<%=RadComboBox3.ClientID %>");
}

ASP.NET:

<telerik:RadToolBar
                ID="RadToolBar1"
                Skin="Windows7"
                EnableRoundedCorners="true"
                EnableShadows="true"
                runat="server"
                Width="100%"
                OnClientButtonClicking="BlockEditor_RadToolBar_Top_ClientButtonClicking"
                OnClientLoad="RadControls_Load" >
                <Items>
                    <telerik:RadToolBarButton Text="Size" Group="Align" CheckOnClick="true">

Hello,

Since the RadComboBox is inside the ItemTemplate, it is not directly available on the page. Try the following method to access it.
Javascript:

function RadControls_Load(sender, args)
{
 var combo= sender._getControl("RadComboBox1")
}

Thanks,
Shinu.

Hi, 

Your code is not worked:

Microsoft JScript runtime error: Object doesn't support property or method '_getControl'

Hi,

You can get the RadComboBox client-side object in this way:

function RadControls_Load(sender, eventArgs) {

    var combo = sender.get_items().getItem(0).findControl("RadComboBox1");
    alert(combo.get_text());
    var combo2 = sender.get_items().getItem(1).findControl("RadComboBox3");
    alert(combo2.get_text());
}
