Hi All, Looking through the samples and API docs, the only direct access to a feature's attachments is via FeatureLayer::QueryAttachmentInfos().  Is there, or will there be in v2.2 of the API, a similar method for a MapServer layer?  The only way I can see to do it now is through the service's REST end point. The code below is an adaptation of the ESRI Identify sample which uses the REST serive to check for attachments and builds a series of hyperlink buttons to open them if so.  I can't really use the AttachmentEditor control for this since it a) requires a FeatureLayer and most of my services do not have this enabled, b) the Identify task returns results from multiple layers, and c) I don't want folks to be able to add or delete attachments. Anyone know of another way to do this? Thanks,  Terry private void IdentifyTask_ExecuteCompleted(Object sender, IdentifyEventArgs args)         {             if (this.Visibility == Visibility.Collapsed)             {                 this.Visibility = Visibility.Visible;

I've created a user control which contains a combobox populated w/ the names of the layers in my map and a time slider.  When the user selects a layer in the combobox, it checks to see if the selected layer is a dynamic layer with a valid timeextent.  If so, I try to set the timeslider's min, max and value properties using that layer via bindings.  This seems to work (in debug timeControl has valid properties at the end of cbxLayers_SelectionChanged) but when the user changes the date range in the slider, the data on the map do not change to reflect that time period.  One thing to note is that the layers in the map are all added when the maps loads, controlled by a parameter passed in.  This means I cannot set the binding in the XAML as the map may not contain any layers which support or have a TimeExtent. Anyone see what I'm missing?  Thanks, TG XAML                                 <esri:TimeSlider x:Name="timeControl" Grid.Row="1"  TimeMode="TimeExtent"                                         PlaySpeed="0:0:1.5" Height="20" Width="200"/> CS private void cbxLayers_SelectionChanged(object sender, SelectionChangedEventArgs e)         {             ArcGISDynamicMapServiceLayer dlyr = null;             ComboBoxItem cbi = ((sender as ComboBox).SelectedValue as ComboBoxItem);             foreach (Layer l in _Map.Layers)             {                 if (l.ID.ToLower() == cbi.Content.ToString().ToLower())                 {                     if (l is ArcGISDynamicMapServiceLayer)  // need to add other time enabled layers later..                     {                         dlyr = l as ArcGISDynamicMapServiceLayer;                     }                     break;                 }             }             // time slider is in a tab control, on a tab called tabTime - hide if layer does not support Time Extent             TabItem tab = tabQueryType.FindName("tabTime") as TabItem;                        if (dlyr == null)             {                 tab.Visibility = Visibility.Collapsed;                            }             else if (dlyr.TimeExtent == null)             {                 tab.Visibility = Visibility.Collapsed;             }             else             {                 tab.Visibility = Visibility.Visible;                 Binding b = new Binding("Layers[" + dlyr.ID + "].TimeExtent.Start");                 b.Source = _Map;                 b.Mode = BindingMode.OneWay;                 timeControl.SetBinding(TimeSlider.MinimumValueProperty, b);                 b = new Binding("Layers[" + dlyr.ID + "].TimeExtent.End");                 b.Source = _Map;                 b.Mode = BindingMode.OneWay;                 timeControl.SetBinding(TimeSlider.MaximumValueProperty, b);                 b = new Binding("Layers[" + dlyr.ID + "].TimeExtent");                 b.Source = _Map;                 b.Mode = BindingMode.OneWay;                 timeControl.SetBinding(TimeSlider.ValueProperty, b);                 List<DateTime> times = new List<DateTime>();                 DateTime dt = dlyr.TimeExtent.Start;                 while (dt < dlyr.TimeExtent.End)                 {                     times.Add(dt);                     dt = dt.AddDays(7);                 }                 timeControl.Intervals = times;             }             tabQueryType.SelectedIndex = 0;         } ...

Is there a way to open AGX and pass in parameters to a tool?  What I'd like to do is add a button to another application I have that opens AGX and passes an address to the Find tool, so the user can see the location on a map & find the lat longs for recording in a data form.  Thanks!
