If you are displaying your results in a datagrid you can create a template column to properly format your hyperlink and build the first part of the url to your file.  For example if in your attribute table you are only storing the attachment file name, file.pdf for example, you could create a template column in your xaml like this: <UserControl.Resources>     <DataTemplate x:Key="DocSource">         <HyperlinkButton Foreground="White" NavigateUri="{Binding Attributes[source_doc], StringFormat=http://www.YourSite/SourceDocs/\{0\}}" Content="{Binding Attributes[source_doc]}" TargetName="_blank" />      </DataTemplate> </UserControl.Resources> Then in your QueryTask_ExecuteCompleted you would build the datagrid columns at runtime, rather than before hand.  As you loop through the featureset to generate your columns you listen for the field source_doc.  When you get to that column you generate the column using the DataTemplate above. ExecuteCompleted Code if (featureSet != null && featureSet.Features.Count > 0)             {     int rec = 0;                 foreach (var feature in featureSet.Features)                     feature.Attributes["Rec"] = ++rec;                         List<string> fields = new List<string>();                                 //generate the first column for record index                 DataGridTextColumn dataGridTextColumnRec = new DataGridTextColumn();                 Binding Recbinder = new Binding();                 Recbinder.Path = new PropertyPath("Attributes[Rec]");                 dataGridTextColumnRec.Header = "Rec";                 Recbinder.Mode = BindingMode.OneWay;                 dataGridTextColumnRec.Binding = Recbinder;                 QueryDetailsDataGrid.Columns.Add(dataGridTextColumnRec);                 //generate the other columns                 foreach (var item in featureSet.FieldAliases)                 {                     if (item.Value == "source_doc") //Create a hyperlink column for document link      {       DataGridTemplateColumn templateColumn = new DataGridTemplateColumn();       templateColumn.Header = "Source Doc";       templateColumn.CellTemplate = (DataTemplate)Resources["DocSource"];       QueryDetailsDataGrid.Columns.Add(templateColumn);      }      else      {      DataGridTextColumn dataGridTextColumn = new DataGridTextColumn();                     Binding binder = new Binding();                     fields.Add(item.Value);   //FieldAliases is a Dictionary, the field name being the key and the field alias being the value.                     binder.Path = new PropertyPath("Attributes[" + item.Key + "]");                     dataGridTextColumn.Header = item.Value;                     binder.Mode = BindingMode.TwoWay ;                     dataGridTextColumn.Binding = binder;                     QueryDetailsDataGrid.Columns.Add(dataGridTextColumn);      }                 }         foreach (Graphic feature in featureSet.Features)                 {                  feature.Symbol = LayoutRoot.Resources["DefaultResultLineSymbol"] as LineSymbol;                  selectionGraphicslayer.Graphics.Insert(0, feature);                 }                 } You can create as many data templates as you need, then add another if statement to listen for them.

What method are you using to calculate your buffer distance, Geodesic or Planar?  I have found that in my neck of the woods, Washington State, that the planar projection when used for calculating distances is very inaccurate.  I always have to use Geodesic in my apps. ESRI has an example of adding a buffer to a point found here,http://resources.arcgis.com/en/help/silverlight-api/samples/start.htm#BufferPoint, but I am sure that you have already seen that. Hope that helps! ... View more

I don't know if you figured this out yet, but I have a solution for you if you haven't.  Using a converter, like you mentioned, you can bind your thumbnail image to the source of an image control, example: <Image Source="{Binding [Thumbnail_Image], Converter={StaticResource uriConverter}}"/> Below is the code for the converter class: using System; using System.Collections.Generic; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Shapes; namespace Converters { public class UriConverter : IValueConverter        {            #region IValueConverter Members               public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)            {                string uri = value as string;                if (uri != null)                    return "http://www.YourSite.com/Thumbnails/" + uri;                else                    return null;            }               public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)            {                throw new NotImplementedException();            }               #endregion        }    } Hope this helps! ...

Over on Codeplex there is a reference to v3.2 that was posted on November 4th.  So hopefully they are getting close.  Also to the OP, you can find the source code to the api at Codeplex. http://esrisilverlight.codeplex.com/releases/view/114370 ... View more

I am using the measuring tools and have found them to be adequate depending on how big of an area or how long of a distance your are measuring.  I tested them by measuring known distances, for example a football field.  I found it to be pretty close, within 6 inches or so when measuring 20 yards.  It was however off by almost 3 yards when measuring 100 yards.  Granted there will be some variance depending on how good your aerial imagery is.  I would say that they should be used for simple approximations and general planning purposes only, the quick and dirty stuff.  They are certainly no substitute for a survey. ...

Ok so after a bunch of searching the forums for people with similar issues I have modified my code to dynamically generate the columns on its own based on the query results. Before I was manually adding them for every different situation, definitely not the way to do it...But this works great!  Well it mostly works great.  The results for some reason still tack on those extra Geometry attribute columns for every result.  Strange, any idea's? My Modified code: private void MySelectionObject_DrawComplete(object sender, ESRI.ArcGIS.Client.DrawEventArgs args)         {             ResultsDisplay.Visibility = Visibility.Visible;             MySelectionObject.IsEnabled = false;             selectionGraphicslayer.ClearGraphics();       //Search Facilities Service - Facilities Layer    if (ddlSelectSystem.SelectedIndex == 0) //Facilities Service    {     if (ddlSelectLayer.SelectedIndex == 0) //Facilities Layer     {      QueryTask queryTask = new QueryTask("myMapServiceURL");               queryTask.ExecuteCompleted += QueryTask_ExecuteCompleted;               queryTask.Failed += QueryTask_Failed;               // Bind data grid to query results               Binding resultFeaturesBinding = new Binding("LastResult.Features");               resultFeaturesBinding.Source = queryTask;               QueryDetailsDataGrid.SetBinding(DataGrid.ItemsSourceProperty, resultFeaturesBinding);               Query query = new ESRI.ArcGIS.Client.Tasks.Query();               // Specify fields to return from query               query.OutFields.Add("FAC_ID, SHORT_NAME, FULL_NAME, ACQUI_YEAR, LAT, LONG, NORTHING, EASTING, USE_CD, USE_DESC, Area_Num, Addr_Num, Addr_Name, Addr_Pre, Addr_Sufix, City_Name, CNTY_Name, Floor_CNT, Area_Name, Zip_Code, Gross_SQFT");               query.Geometry = args.Geometry;               // Return geometry with result features               query.ReturnGeometry = true;               query.OutSpatialReference = MyMap.SpatialReference;               queryTask.ExecuteAsync(query);     }    }       //Search Chilled Water System - Valves Layer         } private void QueryTask_ExecuteCompleted(object sender, ESRI.ArcGIS.Client.Tasks.QueryEventArgs args)         {             FeatureSet featureSet = args.FeatureSet;             if (featureSet == null || featureSet.Features.Count < 1)             {                 //MessageBox.Show("No features returned from query");                               return;             }             if (featureSet != null && featureSet.Features.Count > 0)             {     int rec = 0;                 foreach (var feature in featureSet.Features)                     feature.Attributes["Rec"] = ++rec;                         List<string> fields = new List<string>();                                 //generate the first column for record index                 DataGridTextColumn dataGridTextColumnRec = new DataGridTextColumn();                 Binding Recbinder = new Binding();                 Recbinder.Path = new PropertyPath("Attributes[Rec]");                 dataGridTextColumnRec.Header = "Rec";                 Recbinder.Mode = BindingMode.OneWay;                 dataGridTextColumnRec.Binding = Recbinder;                 QueryDetailsDataGrid.Columns.Add(dataGridTextColumnRec);                 //generate the other columns                 foreach (var item in featureSet.FieldAliases)                 {                     DataGridTextColumn dataGridTextColumn = new DataGridTextColumn();                     Binding binder = new Binding();                     fields.Add(item.Value);   //FieldAliases is a Dictionary, the field name being the key and the field alias being the value.                     binder.Path = new PropertyPath("Attributes[" + item.Key + "]");                     dataGridTextColumn.Header = item.Value;                     binder.Mode = BindingMode.TwoWay ;                     dataGridTextColumn.Binding = binder;                     QueryDetailsDataGrid.Columns.Add(dataGridTextColumn);                 }         foreach (Graphic feature in featureSet.Features)                 {                     feature.Symbol = LayoutRoot.Resources["ResultsFillSymbol"] as FillSymbol;                     selectionGraphicslayer.Graphics.Insert(0, feature);                 }                 ResultsDisplay.Visibility = Visibility.Visible;             }       DataDisplayTitle.Text = featureSet.Features.Count + " - Results Found";                MySelectionObject.IsEnabled = true;       MySelectionObject.DrawMode = DrawMode.None;            } ...

Thank You!!! You got me pointed in the right direction!  I used the MapGesture Event and did a quick if statement to determine whether the user did a tap then ran my identify task.  [INDENT]private void MyMap_MapGesture(object sender, Map.MapGestureEventArgs args)         {             if (args.Gesture == GestureType.Tap )             {                 GraphicsLayer layer = this.MyMap.Layers["IdentifyIconGraphicsLayer"] as GraphicsLayer;                 layer.ClearGraphics();                 Graphic graphic2 = new Graphic                 {                     Geometry = args.MapPoint,                     Symbol = this.LayoutRoot.Resources["CougarWait"] as Symbol                 };                 Graphic item = graphic2;                 layer.Graphics.Add(item);                 IdentifyTask task = new IdentifyTask("http://......./MapServer");                 task.ExecuteCompleted += new EventHandler<IdentifyEventArgs>(this.IdentifyTask_ExecuteCompleted);                 task.Failed += new EventHandler<TaskFailedEventArgs>(this.IdentifyTask_Failed);                 IdentifyParameters identifyParameters = new IdentifyParameters                 {                     LayerOption = LayerOption.all,                     SpatialReference = this.MyMap.SpatialReference,                     MapExtent = this.MyMap.Extent,                     Width = (int)this.MyMap.ActualWidth,                     Height = (int)this.MyMap.ActualHeight,                     Geometry = args.MapPoint                 };                 task.ExecuteAsync(identifyParameters);             }                    }[/INDENT] Thanks again for your help! ...
