Static validators emitting "nbsp;"

I have a .NET question. For my particular application which is catoring to 开发者_开发问答mobile devices (specifically blackberry at the moment), I am using validators (required field validator to be exact).

The problem is that I have disabled javascript from asp.net (by specifying ClientTarget="ie4", but setting EnableClientScript="False" on the validator tags has the same effect). The actual issue is that when the validator is invisible, it emits "nbsp;" instead of nothing, is there some way to override this unwanted result?

Please do not reply solutions that include css or javascript, as I am unable to use either in my particular situation.

Thank you.

Display=Static means that a single nonbreaking space ("&nbsp") is emitted. This last behavior exists so that table cells containing only validators do not collapse to nothing when valid.

From here.

As Frédéric Hamidi said, you could try Display=Dynamic instead, but if you're insistent on using Display=Static, I think your only option is to extend the validator and override the Render method.

protected override void Render(HtmlTextWriter writer)
{
   if (this.Display == ValidatorDisplay.Static && this.IsValid)
   {
       writer.Write(String.Empty);
   }
   else
   {
       base.Render(writer);
   }
}

Static validators will indeed render an   entity when hidden.

Try using dynamic validators instead, by setting their Display property to ValidatorDisplay.Dynamic.
