I am using the find tool located at http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Find and its great but I need to be able to zoom to the feature that it found. Either an auto zoom or a click to zoom. Does anyone know how to add this function to the tool?


Thanks,
Jerry

With the sample you pointed out, you can get autozoom by adding this code in find.xaml.cs:

......
graphicsLayer.Graphics.Add(graphic);
 
// Zoom to selected graphic
var geometry = graphic.Geometry;
if (geometry.Extent.Width == 0 && geometry.Extent.Height == 0)
{
// Zoom to point is not supported -> need to expand the geometry (we might also just Pan)
var center = geometry.Extent.GetCenter();
double size = MyMap.MinimumResolution == 0 ? 1000 : MyMap.ActualWidth * MyMap.MinimumResolution * 4.0;
geometry = new ESRI.ArcGIS.Client.Geometry.Envelope(center.X - size / 2, center.Y - size / 2, center.X + size / 2, center.Y + size / 2);
}
MyMap.ZoomTo(geometry);
