Layer Column Names to Dropdown

BrianLeroux — Wed, 15 Feb 2012 13:51:39 GMT

Is there a way to get the column names of a dynamic map service into a drop down. What i am trying to do is build a tool that would allow me to select a field name from the drop down and enter a search term for that field to filter the layer. Any help is appreciated.

To get the list of all fields for all sublayers of a dynamic layer you can try GetAllDetails(,); for a particular sublayer use GetDetails(int,,).

You can use the following code:
XAML

  <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">
  <ComboBox x:Name="LayerNames">
   <ComboBox.ItemTemplate>
    <DataTemplate>
     <TextBlock Text="{Binding Value.Name}"/>
    </DataTemplate>
   </ComboBox.ItemTemplate>
  </ComboBox>
   <ComboBox x:Name="FieldNames" DataContext="{Binding ElementName=LayerNames, Path=SelectedItem}"
       ItemsSource="{Binding Value.Fields}">
    <ComboBox.ItemTemplate>
    <DataTemplate>
     <TextBlock Text="{Binding Name}"/>
    </DataTemplate>
   </ComboBox.ItemTemplate>
  </ComboBox>
  </StackPanel>

Code-Behind

   var layer = new ArcGISDynamicMapServiceLayer() { Url = "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/MapServer" };
   layer.GetAllDetails((a, b) =>
    {
     if (b != null)
      MessageBox.Show(b.Message);
     else    
      LayerNames.ItemsSource = a;
    });
