I have a few code lines like this,

```
public void rt_changed(object sender, AjaxControlToolkit.RatingEventArgs e)
{
    //Label l = sender as Label;
    foreach (DataListItem li in datalist.Items)
    { 

      Label l = li.FindControl("nl") as Label;

    }
    Label3.Text = l.ToString(); // l values is not getting
 }

```

Here the variable l is null. I know it's happening because the declaration of l has been made inside the scope of the foreach. I don't know how to call the variable with value in globally.
