Hi I want to show just one Template out of a template group in a service in code

[MuralidharMoka]

Hi I have been trying to show only on template from the service.

I am trying to show just one template from my service.The template will just draws a polygon.
So I was trying to use the ESRI Sample code which is the following,

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitTemplatePicker

This example gets all the templates in each of the service.

My requirement is to get on template from the whole template group in the service.
I wanted to do thorough this in the Template_loaded code.

I though I can acess the Template group and then filter it by the names of the template,
but I dont know how to acess the template group on the code behind.

This is what I tried.
        private void MyTemplatePicker_Loaded(object sender, RoutedEventArgs e)
        {
            string[] myLayerIDs = { "Evacuation Perimeter" };
            MyTemplatePicker.LayerIDs = myLayerIDs;
            IEnumerable<TemplateGroup> temp = MyTemplatePicker.TemplateGroups;
        }

I just used only one service "Evacuation Perimeter" this has two templates ,which can draw Yellow and green Polygons.

I just wanted to get only one template say just the Yellow , wanted to do from code behind.
can any one help me. Just give me an idea.

At this line I dont get the template group.

////My XAML looks like this with template style code. In the XMAL when I look at the the template picker style code.
I see this line  ItemsSource="{TemplateBinding TemplateGroups}"
Where is the TemplateGroups property getting from? How can I acess that in code.
Even if I acess I do not know how to proceed until I filter a template.


<toolkit:TemplatePicker x:Name="MyTemplatePicker"
                                    Map="{Binding ElementName=MyMap, Mode=OneWay}"
                                    ShowAttributesOnAdd="True"
                                    Loaded="MyTemplatePicker_Loaded"
                                  >
                <toolkit:TemplatePicker.Template>
                    <ControlTemplate  TargetType="toolkit:TemplatePicker">
                        <ItemsControl ItemsSource="{TemplateBinding TemplateGroups}">
                            <ItemsControl.ItemTemplate>
                                <DataTemplate>
                                    <StackPanel Orientation="Vertical">
                                        <TextBlock Text="{Binding Name}" Foreground="{Binding Background, RelativeSource={RelativeSource TemplatedParent}}" />
                                        <ItemsControl ItemsSource="{Binding Templates}">
                                            <ItemsControl.ItemsPanel>
                                                <ItemsPanelTemplate>
                                                    <StackPanel Orientation="Horizontal" />
                                                </ItemsPanelTemplate>
                                            </ItemsControl.ItemsPanel>
                                            <ItemsControl.ItemTemplate>
                                                <DataTemplate>
                                                    <Grid>
                                                        <Button HorizontalContentAlignment="Center" Margin="2" Command="{Binding Editor.Add}" CommandParameter="{Binding TypeID}" ToolTipService.ToolTip="{Binding Name}">
                                                            <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center" Orientation="Vertical">
                                                                <esriPrimitives:SymbolDisplay Height="25" Width="30" Symbol="{Binding Symbol}" />
                                                            </StackPanel>
                                                        </Button>
                                                    </Grid>
                                                </DataTemplate>
                                            </ItemsControl.ItemTemplate>
                                        </ItemsControl>
                                    </StackPanel>
                                </DataTemplate>
                            </ItemsControl.ItemTemplate>
                        </ItemsControl>
                    </ControlTemplate>
                </toolkit:TemplatePicker.Template>
               
            </toolkit:TemplatePicker>

If My question was confusing.

From the Template Picker Sample

http://help.arcgis.com/en/webapi/sil...TemplatePicker


I  wanted to show just the Template which draws Yellow Polygons.
How can we do this from code behind. That was my question in short.

You can exclude symbol templates from other layers, by setting TemplatePicker.LayerIDs property. http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client.Toolkit~ESRI.ArcGIS.Client.To...

In your XAML, add this code:

LayerIDs="Evacuation Perimeter"

If you want to further limit the symbol templates to specific symbols, you can create a two-way binding on TemplatePicker.Templates and your own class that implements INotifyPropertyChanged.

public MainPage()
{
 InitializeComponent();

 MyTemplates myTemplates = new MyTemplates();
 Binding b = new Binding("Templates");
 b.Source = myTemplates;
 b.Mode = BindingMode.TwoWay;
 MyTemplatePicker.SetBinding(TemplatePicker.TemplatesProperty, b);
}

public class MyTemplates : INotifyPropertyChanged
{
 public MyTemplates() { }
 private IEnumerable<SymbolTemplate> templates;
 public IEnumerable<SymbolTemplate> Templates 
 {
  get { return templates; }
  set
  {
   if (templates != value && value != null)
   {    
    SymbolTemplate st = null;
    foreach (var t in value)
    {
     if (t.Name == "Mandatory Evacuation")
     {
      st = t;
      break;
     }
    }
    if(st != null)    
    {
     templates = new List<SymbolTemplate>() { st };
     if (PropertyChanged != null)
      PropertyChanged(this, new PropertyChangedEventArgs("Templates")); 
    }
   }
  }
 }
 public event PropertyChangedEventHandler PropertyChanged;
}

Another way is to use Editor.Add instead of TemplatePicker and for Button.Content, you can consider using ESRI.ArcGIS.Client.Toolkit.Primitives.SymbolDisplay.

Thank you very much.

I did not know that editor can do this.
Would you pls point me to any editor example,
I do not know how to use it.

if not if f = MyMap.Layers["FeatLayer"] as FeatureLayer;

how do I proceed next with if say I have MyEditor as the instance.

would you pls write some sample code for me to start.

Thanks for the great help

Thanks

This is a good example of Editor: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#EditToolsAutoSave
