Making the currently selected menuitem unselectable.

[Gareth]

Hi,
Is it possible to make the currently selected item unselectable? If so how would I go about this, my panelbar is bound to a datasource.
Thanks
Gareth

Hello Gareth,

I'm afraid we cannot fully understand your request. Could you please elaborate? What do you mean by unselectable item if it is currently selected?

Hi,
Sorry if I was not clear basically, when a menuitem is selected and the content is loaded to the page. I would like to be able to disable that menu item. So there will always be one disabled menuitem in the menu as a user navigates through the items.
Cheers

Hi Gareth,

Thanks for the details. Here's a sample code snippet that shows the needed appraoch.

    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>

        <script type="text/javascript">
        function OnClientItemClicked(sender, eventArgs)
        {
            for (var i=0; i< sender.get_allItems().length; i++)
            {
                sender.get_allItems()[i].enable();
            }

            var panelitem = eventArgs.get_item();
            panelitem.disable();
        }
        </script>

        <telerik:RadPanelBar runat="server" ID="RadPanelBar1" OnClientItemClicked="OnClientItemClicked">
            <CollapseAnimation Duration="100" Type="None" />
            <ExpandAnimation Duration="100" Type="None" />
            <Items>
                <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
                    <Items>
                        <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
                        </telerik:RadPanelItem>
                        <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 2">
                        </telerik:RadPanelItem>
                    </Items>
                </telerik:RadPanelItem>
                <telerik:RadPanelItem runat="server" Text="Root RadPanelItem2">
                    <Items>
                        <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
                        </telerik:RadPanelItem>
                        <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 2">
                            <Items>
                                <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1">
                                </telerik:RadPanelItem>
                                <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 2">
                                </telerik:RadPanelItem>
                                <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 3">
                                </telerik:RadPanelItem>
                            </Items>
                        </telerik:RadPanelItem>
                        <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 3">
                        </telerik:RadPanelItem>
                    </Items>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>
    </form>
