Highlight graphics from results window mouse over

Question

Hey,

I have the results from a querytask in a drop down window.  The locations are displayed with a graphic.  I was wondering how to highlight or change the graphic when you mouse over the results in the dropdown window. I would like the user to know which graphic goes with the result.

Thanks, Chris

A much more efficient way would be to use the visual states instead of replacing the symbol as suggested. It will perform better and not "flicker".

Here is the code that I used to get it to work.

Chris
 private void TextBlock_MouseEnter(object sender, MouseEventArgs e)
        {
            
            QueryResultData HiLight = (QueryResultData)(sender as FrameworkElement).DataContext;
            
            Graphic g = getGraphic(HiLight);

g.Symbol = SearchSelectedSymbol;
            if (g != null)
            {
                g.Select();
                g.SetZIndex(1);
            }
        }

private void TextBlock_MouseLeave(object sender, MouseEventArgs e)
        {
            QueryResultData HiLight = (QueryResultData)(sender as FrameworkElement).DataContext;

Graphic g = getGraphic(HiLight);

g.Symbol = SearchPictureSymbol;
            if (g != null)
            {
                g.Select();
                g.SetZIndex(0);
            }
        }

private Graphic getGraphic(QueryResultData HiLight)
        {
            GraphicsLayer layer = MyMap.Layers["MyGraphicsLayer"] as GraphicsLayer;
            if (HiLight != null && layer != null)
            {
             
                foreach (Graphic g in layer.Graphics)
                {
                    
                    if (g.Geometry == HiLight.SHAPE)
                    {
                        return g;
                    }
                }
            }
            return null;
        }
