I want to be able to unhighlight a particular series.

Currentlt I am doing the following

private void chart1_Highlighting(object sender, HighlightingEventArgs e)

{

Debug

.WriteLine(string.Format("Highlighting {0}",e.Series));

if (e.Series ==1){

chart1.Highlight.ClearHighlight(sender);

}

} 

but the problem is the other series don't get highlighted again, unless I click the chart again. I can see the highlight event stop firring.

I fixed it by replacing the resolver

  if (e.Series ==1)

{

  if (!(e.Resolver is NullHighlightResolver))

  {

if (_nullHighlightResolver == null)

{

 _nullHighlightResolver = new NullHighlightResolver(e.Resolver);

}

e.Resolver = _nullHighlightResolver;

  }

 //Disable hightlight on an item

public class NullHighlightResolver : IHighlightResolver

{

 private readonly IHighlightResolver _resolver;

 public NullHighlightResolver(IHighlightResolver resolver_)

 {

_resolver = resolver_;

 }

 public HighlightState GetState(HighlightType itemType, object item)

 {

return HighlightState.Never;

 }

 public Highlightable CanHighlight(HighlightType itemType, object item)

 {

return Highlightable.No;

 }

 public bool OnKey(bool down, KeyEventArgs args)

 {

return _resolver.OnKey(down, args);

 }

 public HighlightingEventArgs GetHighlightingEventArgs()

 {

return _resolver.GetHighlightingEventArgs();

 }

}
