Well I found out the solution  here it is If you want the area of the part that is inside the envelope you have to query with esriSpatialRelOverlaps or esriSpatialRelInstersects and perform a clip operation on all the returned geometries using ITopologicalOperator.Clip against the envelope. If you are using another geometry than an envelope to clip against you should be using ITopologicalOperator.Intersect. As always whe performing geometrical operations you should ensure that both geometries have the same spatial reference. ... View more

Thnx for your reply I saved the XMin, XMax, YMin, YMax from the feature layer calculated the envelope and zoomed to it , it worked fine anywys 🙂 ... View more

If you are loading multiple layers at runtime at once and you want to do some processing after all of them have finished updating, you'll have to keep a counter to find out when all of them have completed. Then you can calculate the extent from all layers by using Union() and do your zoom ... I hope that's what you are looking for; I'm not quite sure of your scenario. [ATTACH=CONFIG]12111[/ATTACH] Hi thanks you for your reply.. I am sorry I did not give enough information about the query.. I have a query where the input values need me to query upto 3 ranges and I return 3 thematics with different symbology on the map therefore I have created 3 layers with different symbology but same data and created a service to access it.. here I am adding 3 feature layers  onto the map .Since the query keysin values in range, for everyvalue keydin I create a new feature layer and display it on the map 1 feature layer for every range. so after adding 3 different feature layers I would like to zoom to its extent. therefore I need to either merge(ie union the feature layer) else add up the extents.. is it possible to add the extents so that I can fix all the 3 feature layer on the map.. Please guide... ... View more

The default legend style doesn't show disabled scrollbars. Check that there is no implicit style defined for the legend in your project (most generally in app.xaml) that might override the default template. Hey dbroux thanks you were right the legend style was defined in app.xaml I changed it it solved my problem thanks a bunch 🙂 ... View more

HI, I have website with mouseover information tool where i run a query from the database everytime the mouse moves over the map but when  I move the mouse towards the window edges/corners the information texblock is chopped away it is not absolute Please guide me as to how the keep the mouse over information within the map boundary my code goes like this <!--MouseOver Information-->             <Border x:Name="m_maptip" CornerRadius="10,10,0,0"                 VerticalAlignment="Top" HorizontalAlignment="Left"  Visibility="Collapsed"                 Background="White" BorderThickness="3" BorderBrush="#3c91c0" Opacity="0.8">                 <StackPanel>                     <sdk:Label x:Name="m_txt_maptip_header" FontFamily="Arial" FontSize="16" Foreground="Red"/>                     <TextBlock x:Name="m_txt_maptip" Text="Line" Foreground="Black" FontSize="12"/>                 </StackPanel>             </Border> I populate the information into the textblock dynamically                 KeyValuePair<int, string> kvpIdentifyLayer = (KeyValuePair<int, string>)cmbxLayerIdentify.SelectedItem;                 m_txt_maptip.Text = strDisplayInfo;                 m_txt_maptip_header.Content = "Layer: " + kvpIdentifyLayer.Value;                 m_maptip.Visibility = Visibility.Visible;                 m_maptip.Margin = new Thickness(_last_point.X + 10, _last_point.Y + 10, 0, 0);                 m_txt_maptip_header.Width = m_txt_maptip.Width; Please guide ...

. The default legend template uses a TreeView which has a built-in scrollviewer. But this scrollviewer should not be visible if not needed. Look at this sample : http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#LegendSimple The scrollbars are only visible when needed. If, for any reason, you need to change the default behavior, you can restyle the legend control (using EditTemplate functionalty in Blend) and use any other container to replace the treeview. HI thanks for your reply tried everything but still unable to hide it. the scroll is disabled but is always visible my code goes like this <Grid x:Name="panelCustomLegend" HorizontalAlignment="Right" Margin="0,50,80,0" VerticalAlignment="Top" ScrollViewer.VerticalScrollBarVisibility="Hidden"                         Visibility="Visible" Background="Black" >                     <Grid.RowDefinitions>                         <RowDefinition Height="20"/>                         <RowDefinition Height="*"/>                     </Grid.RowDefinitions>                     <sdk:Label Name="lblCustomLegend" Foreground="White" Grid.Row="0" MinWidth="50" MaxWidth="200" HorizontalAlignment="Center" FontSize="12" />                     <esri:Legend Map="{Binding ElementName=map}" Grid.Row="1" ScrollViewer.HorizontalScrollBarVisibility="Hidden"                          ShowOnlyVisibleLayers="True" x:Name="CustomLegend" Refreshed="CustomLegend_Refreshed" >                                                                        <esri:Legend.MapLayerTemplate>                             <DataTemplate>                                 <StackPanel Orientation="Horizontal">                                         <sdk:Label Content="{Binding Description}"/>                                     <!--<Slider Maximum="1" Value="{Binding Layer.Opacity, Mode=TwoWay}" Width="50" />-->                                 </StackPanel>                             </DataTemplate>                         </esri:Legend.MapLayerTemplate>                         <esri:Legend.LegendItemTemplate>                             <DataTemplate >                                 <StackPanel Orientation="Horizontal">                                     <Image Source="{Binding ImageSource}"></Image>                                     <sdk:Label Content="{Binding Label}" MinWidth="50"/>                                     <sdk:Label Content="{Binding Tag}"/>                                 </StackPanel>                             </DataTemplate>                         </esri:Legend.LegendItemTemplate>                         <esri:Legend.LayerTemplate>                             <DataTemplate>                                 <CheckBox Content="{Binding Label}"                                IsChecked="{Binding IsEnabled, Mode=TwoWay}"                             IsEnabled="{Binding IsInScaleRange}" >                                 </CheckBox>                             </DataTemplate>                         </esri:Legend.LayerTemplate>                 </esri:Legend>             </Grid> [ATTACH=CONFIG]11518[/ATTACH] Can you please guide me with the modification to hide to scroll ..... ...

Normally this situation happens when the ''event's route id'' is not found in the Route layer. Instead of dropping the unreferenced events, it keeps it but with a geometry equal to 'null'. You could first verify for one of these events that failed, what is the RouteID written. Then look in your Route Layer if you can really find this route ID. Yup you were right thnx 🙂 ... View more
