How to access the variable globally?

Anonymous User187313-Nov-2014

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 a value in globally.

You just need to move the declaration of the l variable outside of the loop to make it available. You can declare (tell what it is) in a different place than where you assign it a value.

public void rt_changed(object sender, AjaxControlToolkit.RatingEventArgs e)
{
  // Declare l, also give it a default value, in the case that datalist is empty.
  Label l = null;
  foreach (DataListItem li in datalist.Items)
  { 
    l = li.FindControl("nl") as Label;
  }
  Label3.Text = l.ToString(); // l values is not getting
}

Please note that l will only get assigned to the last value in the datalist collection, which probably isn't exactly what you want.
