Question

Very simple and stupid question.

i have a page class

public partial class ProtectWayItem : System.Web.UI.UserControl
    {
        public int Count { get; set; }

        protected void Page_Load(object sender, EventArgs e)
        {
                 Count = 10;
        }
    }

and how i can set div id equal Count.

I mean something like:

<div id='<%# Count %>' > </div>

Answer 1

You have to use = instead #

<div id='<%= Count %>' >

And if you want to call with the # sign then you need to call a DataBind() method..

protected void Page_PreRenderComplete(object sender, EventArgs e)
{
    DataBind();
}

here is what each expression means

• The <%= expressions are evaluated at
  render time
• The <%# expressions are evaluated at
  DataBind() time and are not evaluated
  at all if DataBind() is not called.
• <%# expressions can be used as
  properties in server-side controls.
  <%= expressions cannot.
