Trying to clear initial content of a group of TextBoxes, the set of codes below, is working:

    y = ActiveControl.Text;
  if (y == "A" || y == "B" || y == "C" || y =="D")
     {
          ActiveControl.Text = string.Empty;
     }

But this other set is not working:

  if (ActiveControl[].Text.Contains("A", "B", "C", "D))
      {
         ActiveControl.Text = string.Empty;
      }

Though I prefer the last set of codes to the 1st one.
Somebody help me out please.
Thanks.

It's not working because the Contains method only take a single string as a parameter. And ActiveControl[]? What is that? Why can't you iterate over the controls collection?

Thanks Man, its perfect but I actually prefer ActiveControl.Text.Contains(....) method for other uses.
You're really appreciated.

The trouble is that the second version won't compile. You could try this:

C#

private static string[] validList = new string[] { "A", "B", "C", "D" };
...
if (validList.Contains(ActiveControl.Text))
    {
    ...
    }
