Hello experts.

I am creating new website using webmatrix.

I want to display confirmation message before user decides to really delete something.

How can I do it?

Please have a look at the code attached.

thank you

panJames
*****************************
This is how I fetch data:

var db = Database.Open("StarterSite");
var itemsSelected = db.Query("select * from Items where UserFK = @0", @WebSecurity.CurrentUserId).ToList();


*****************************
This is how I display data:

@foreach (var p in itemsSelected) 
{
	<input type="button" value="Delete!" onclick="itemDelete(@p.id)" />
}


*****************************
itemDelete is actually a javaScript function:

function itemDelete(index)
{
	var r=confirm("Are you sure?");
	
	if (r==true)
	{
		@{
			//this is actually a c# code where I cannot use "index" variable
			var db = Database.Open("StarterSite");
			db.Query("DELETE FROM Items WHERE id = @0", index);
		}
		
	}
	else
	{
	
	}
}

//so I can either:
//learn how to get access to java script variables for my c# code
//or learn how to generate a "are you sure?" form using c#

//additional questions:
//how can I create c# methods to be used within WebMatrix?
//how can I attach them to buttons- like "onclick" in my example?
