Enable and disable item child radmenu

[Fabio Cirillo]

hi,
i need enable and disable the item child of the radmenu depending on the data taken from a database.
For example...
into page aspx into page_load event or page_init, if there're not the record into database the item child witn value 2 must be disable.

this code radmanu is:

<telerik:RadMenu ID="RadMenu1" Runat="server"
EnableRoundedCorners="True" EnableShadows="True" Skin="Sunset">
<Items>
<telerik:RadMenuItem runat="server" Owner="RadMenu1" Text="Immagine profilo">
<Items>
<telerik:RadMenuItem runat="server" ImageUrl="~/Image/Icone/new.png" Owner=""
Text="Nuova" Width="110px" Value="1">
</telerik:RadMenuItem>
<telerik:RadMenuItem runat="server" ImageUrl="~/Image/Icone/view.png" Owner=""
Text="Visualizza" Width="110px" Value="2">
</telerik:RadMenuItem>
<telerik:RadMenuItem runat="server" ImageUrl="~/Image/Icone/delete.png"
Owner="" Text="Elimina" Width="110px" Value="3">
</telerik:RadMenuItem>
</Items>
</telerik:RadMenuItem>
</telerik:RadMenu>

how can i do it? with client side and use javascript or server side and use codce behind?
i use this code:

RadMenu1.Items(0).Items(1).Enabled = false

but into load event dont fuction. this code function only radmenu1_init event. But i must need that function in page_load event because there i load the record from database

 

Second problem i use the radwindows for load a new page and into this i save the record. When i close the radwindows, the item child with value 2 must be enable. So must tu use the javascript code?

Please help me

thanks you

Hi Fabio

The best option that I would suggest is to attach the OnClientLoad event and try disabling the menu item from javascript
aspx

<telerik:RadMenu ID="RadMenu1" runat="server" EnableRoundedCorners="True" EnableShadows="True"
 OnClientLoad="OnClientLoad"Skin="Sunset">


          


JS

<script type="text/javascript">
function OnClientLoad(sender, args)
{
  var menu = $find("<%= RadMenu1.ClientID %>");
  var menuItem = menu.findItemByValue("2");
  menuItem.disable();
}
</script>

Thanks,
Princy.

Hi Suren,

OnClientLoad  is a client-side function that by design accepts one parameter. You can find more info here. Take a look at the working example below:

<telerik:RadScriptManager runat="server"></telerik:RadScriptManager>
        <div>
            <telerik:RadMenu ID="RadMenu1" runat="server" EnableRoundedCorners="True" EnableShadows="True" Skin="Sunset" OnClientLoad="onClientLoad">
                <Items>
                    <telerik:RadMenuItem runat="server" Owner="RadMenu1" Text="Immagine profilo">
                        <Items>
                            <telerik:RadMenuItem runat="server" Owner=""
                                Text="Nuova" Width="110px" Value="1">
                            </telerik:RadMenuItem>
                            <telerik:RadMenuItem runat="server" Owner=""
                                Text="Visualizza" Width="110px" Value="2">
                            </telerik:RadMenuItem>
                            <telerik:RadMenuItem runat="server" Owner="" Text="Elimina" Width="110px" Value="3">
                            </telerik:RadMenuItem>
                        </Items>
                    </telerik:RadMenuItem>
                </Items>
            </telerik:RadMenu>
        </div>
    </form>
    <script>
        var menu;

        function onClientLoad(sender) {
            menu = sender;

            var menuItem = menu.findItemByValue("2");
            menuItem.disable();
        }
    </script>
