Hi, The following code demonstrates how to use EO Menu, ASP.NET AJAX ConfirmButton and ModalPopup Extender together. When user clicks a menu item, ConfirmButton is triggered, which in turns displays a modal popup for user to confirm. Once user confirms the popup, the menu continues to raises server side ItemClick event.
Code: HTML/ASPX

This is interesting, but is there a way to tell which item was clicked? For instance, I don't want to show the panel for every item in the menu, perhaps only the "Format" item.

Also, when dealing with Master Pages, make sure you rework the javascript to use the .ClientID property to get the true id of each control that you reference.

Hi, You can check which item is clicked inside your confirmMenuClick handler, it will be something like this:
Code: JavaScript
function confirmMenuClick(e, info)
{
//Does nothing if the item is not "Format". Note the sample
//code checks "ItemID", so you will need to set the
//item's ItemID property in order for this code to work.
//You can also call getText() to check the item text
if (info.getItem().getItemId() != "format")
return;
//Continue other logics such as displaying confirm dialog....
......
}
Here is the reference for NavigationEventInfo object (type of "info" argument) and NavigationItem object (type of info.getItem()): http://doc.essentialobjects.com/library/1/jsdoc.public.navigatoreventinfo.aspxhttp://doc.essentialobjects.com/library/1/jsdoc.public.navigationitem.aspxAnd yes, the code should be adjusted if you use a master page. For example, instead of using:
Code: JavaScript
document.getElementById("Button1").click();
It should be:
Code: JavaScript
document.getElementById('<%=Button1.ClientID%>').click();
Thanks for pointing this out! Please feel free to let us know if you have any more questions/suggestions.
