RadMenu, Masterpage and ContentPlaceHolder Page

[Patrick Williams]

Hi All,

Could someone help me in understanding how to determine which radmenu item was clicked/selected from a page using master page. I'm trying to get the selectedvalue of that menu item to save to a database and also to determine  which user control to populate on the page.

That is, my radmenu is on my master page and from any page in the application i would like to determine which radmenu item were selected.

Thanks in advance for your response.
Patrick.

Hello Patrick,

You can use SelectedItem property of the menu, because you open a new page and there's a different instance of the menu from the previous page.

I suggest you use the following approach to find the clicked item and select it:

RadMenu menu = (RadMenu)Master.FindControl("RadMenu1");
RadMenuItem currentItem = menu.FindItemByUrl(Request.Url.PathAndQuery);
if (currentItem != null)
   currentItem.Selected = true;

Hi Yana,

The method suggested I cannot use, because some of the page called by navigationUrl will be the same the only difference on this page is that I want to get the selectedValue to determine which User Control to load on that page.

I know i can pass the value that i want with a query string through the navigationUrl but i dont want this value to be visible to ensure adequate  security. I tried also using javascript to get the selectedValue but this was not successful as well. The function "get_selectedItem()" seems to be not working, it does not give me any result.

Hello Patrick,

The other option is to save the value of the selected item in a session variable and after the postback get it from there.

Hi Yana,

Can you please Let me know what is Master in
RadMenu menu = (RadMenu)Master.FindControl("RadMenu1"); Its throwing error for me

Hello,

Master gets a reference to the Master page object. If you are not using a master page in your web site/application the Master will return null. In case calling the FindControl method will throw an error since the object is null.
