radcombobox in radtooltip items update clientside

[Fit2Page]

I am trying to alter the items collection of a radcombobox which is placed in a radtooltip with JS like

 

  <telerik:RadToolTip ID="tt_svg_combo" HideEvent="ManualClose" OffsetX="20" RenderMode="Lightweight" Skin="Default" Width="400" Height="400" runat="server">
       <telerik:RadComboBox ID="rcb_tooltip" runat="server"><Items>
            <telerik:RadComboBoxItem Text="aa" Value="aa" />
                                                             </Items></telerik:RadComboBox>
    </telerik:RadToolTip>

 

 

and JS:

  var ott
                    ott = $find("<%=tt_svg_combo.ClientID%>");
                    var combo = $find("<%= rcb_tooltip.ClientID%>");
                    var items = combo.get_items();
                    combo.trackChanges();
                    var comboItem

var str='1$2$3$4$5'
                    var a = str.split("$");

                    for (i = 0; i < a.length; i++) {
                        comboItem = new Telerik.Web.UI.RadComboBoxItem();
                        comboItem.set_text(a[i]);
                        comboItem.set_value(a[i]);
                        items.add(comboItem);
                    }

                    combo.commitChanges();
                }
              
                setTimeout(function () {
                    ott.show();
                }, 1000);

 

None of the added items are showing up on tooltip show.

When I place rcb on the page itself it works OK

Hello,

The items are added correctly but the dropdown is with lower index that the ToolTip and that is why you do not see the items. Here is a sample implementation of the ComboBox with z-index higher than the ToolTip:

<telerik:RadComboBox ID="rcb_tooltip" runat="server" Style="z-index: 10000">
    <Items>
        <telerik:RadComboBoxItem Text="aa" Value="aa" />
    </Items>
</telerik:RadComboBox>

Here is a forum thread with similar issue: Combobox in Tooltip - show dropdown on load.
