How to change the RadMenu Item backcolor and Image dynamically

[Jagat]

Hello,

  I have a radmenu in the master page. In one of my content pages, I have a timer. The timer checks for a value in the database and based on that value, I would like to change the backcolor and ImageUrl of the menu item(actually,would like the menu item to glow) which means that there is a new message. Right now, I am doing it like this which is of course not working

Am i missing something ?

code- behind
in the timer tick event.( content page)

  Radmenu1.items(5).items(2).backcolor = drawing.color.red
 Radmenu1.items(5).items(2).ImageUrl ="Images/Newmessage.png"

How do I make the menu item glowing? Is there a way to do that?

Appreciate the help
Thanks

Hello,

 I tried it in different way. I am getting the desired output only after the postback . But i don't want the postback there , So I put the Radmenu(in Master page) in the update panel. The problem is, in the asyn postback trigger, which control id do I need to mention. I couldn't give the control ID of the timer which is in the content page.How do i do this?

Hello Jagat,

I would suggest that you try to use one of our controls - either the RadAjaxManager or the RadAjaxPanel that allow ajaxifying other controls that normally would work with postbacks. Take a look at the above mentioned help articles for more information on how to use them.
