RadComboBox + RadTooltip for no items found

[Alan T]

Hi, 

I'm struggling to implement this, i'm not sure why.

I've got a RadComboBox, and i've manually implemented the onitemsrequested event of it, to enable custom loading on demand.

I've then attached my tooltip. Both of which are inside an asp:Panel which is ajaxified using the RadAjaxManager.

<telerik:RadToolTip ID="tt_searchArea_empty" runat="server"
TargetControlID="cbo_searchArea" HideEvent="FromCode" ShowEvent="FromCode"
RelativeTo="Element">
</telerik:RadToolTip>

   

and show it in code behind (search locations is my combobox's datasource).

   

If search_locations.Count <= 0 Then
Me.tt_searchArea_empty.Text = "Could not find any results for """ & e.Text & ""
Me.tt_searchArea_empty.Show()
End If

And to hide it, i've attached this client side event OnFocus of my combobox:

var tt = '<%=tt_searchArea_empty.ClientID %>';
tt.hide();

Hello Alan,

I'm assuming the show part must work. The problem I see with your js code is that you're not using the $find method to grab the instance of the RadTooltip. You js code should look like this:

var tt = $find('<%=tt_searchArea_empty.ClientID %>');
tt.hide();

no, the show part is unfortunately not working.

I'm not sure why, that line of code is definately executing. Perhaps its something to do with it being in an ajaxified panel?

My AjaxManager defintiino is basically:

    <telerik:RadAjaxManager ID="ram_home" runat="server" DefaultLoadingPanelID="ralp_front">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="pnl_searchBox">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="pnl_searchBox" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

where all controls mentioned are inside pnl_searchBox.

I ended up doing this via client side methods instead.
