Hello,

I've been trying to find documentation about the Radmenu1.FindItem property and how to use conditions.
Could someone provide any examples or documentation links?
The problem is that I need to disable all items from a root and show those itens disabled.

Thanks for any help.

Hi Marcio,

You can use FindItemByText, FindItemByValue or FindItemByUrl in order to search an item based on item's text, value or url. See the example shown below.

C#:
 
protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e) 
    RadMenuItem item1 = (RadMenuItem) RadMenu1.FindItemByUrl("http://www.google.com"); 
    RadMenuItem item2 = (RadMenuItem) RadMenu1.FindItemByValue("Value"); 
    RadMenuItem item3 = (RadMenuItem) RadMenu1.FindItemByText("RadMenuItem Text"); 

-Shinu.

Yes, Shinu. Thanks for the reply. You're right and this is very useful. However i'm interested in a property called FindItem only. See below what says Intellisense:

Telerik.Web.UI.RadMenuItem RadMenu.FindItem(Predicate<Telerik.Web.UI.RadMenuItem> match)  
match: The Predicate <> that defines the conditions of element to search for

And I couldn't find any example of it.

Thanks.

Hi Shinu,

I've been able to solve my problem using the code below to disable items from menu that have the same values.
I don't know if its the most correct way to do that but it seems to work. The only thing that I need to do now is to prevent user from assessing pages manually.

    private void DisableItemsFromValue(string valuetodisable)  
    {  
        var items = RadMenu1.GetAllItems();  
        int total_items = items.Count;  
        for (int i=0; i < total_items; i++)  
        {  
            if (items[i].Value == valuetodisable)  
            {  
                items[i].Enabled = false;  
                items[i].NavigateUrl = "";  
            }  
        }  
    } 

Thanks.

Added a new server side method FindItem which has one argument match of type Predicate Generic Delegate. This method can be used to find an Item by some custom criteria.
