Hi Elena,

The Weather Station is quite complex application so I wouldn't recommend it as a starting point for your work with RadMap. It seems to me that it would be better to start from the simple examples in our demo application which demonstrates the most important features of the map control. Then you will be able to select those that you need to implement in your application.

1. InformationLayer is ItemsControl that supports the usage of different item templates. Like most other items controls it allows you to use ItemsTemplateSelector to select the corresponding template based on the data or the map zoom level. I would recommend you to take a look into the following sample in our demo application:

http://demos.telerik.com/silverlight/#Map/DataBinding

2. You can find example which demonstrates major features of the DynamicLayer here:

http://demos.telerik.com/silverlight/#Map/DynamicLayer

Weather Stations - это достаточно сложное приложение. Так что я бы не рекомендовал Вам начинать работу с RadMap  с этого приложения. Оно активно использует различные возможности RadMap. Мне кажется, что было бы лучше начать с более простых примеров в нашем демонстрационном приложении, которое показываетосновные возможности RadMap. После их обзора Вы сможете выбрать те из них, которые необходимы для реализации Вашего приложения.

1. InformationLayer является ItemsControl и позволяет использовать различные шаблоны представления данных. Подобно многим другим ItemsControl он разрешает Вам исполльзовать ItemTemplateSelector для выбора шаблона в зависимости от данных и уровня детализации (ZoomLevel) RadMap. Я бы рекомендовал Вам посмотреть следующий пример:

http://demos.telerik.com/silverlight/#Map/DataBinding

2. Вы можете найти пример, который демонстрирует основные возможности DynamicLayer здесь:

Thanks for your answer, Andrey!

 

I will probably try to use InformationLayer but if it is possible

Correct me if I am mistaken in WetaherStation:

 

From consideration Styles.xaml and Main.xaml to me it is clear that

WeatherStation it is created with application of MVVM pattern and in ViewModel do not form Controls

ViewModel only operates with the data from DynamicSource in collection WetaherInfo

ViewModel defines commands who work with logic of data model, and are binded to Controls from View

All visual behaviour WetaherStation is realised in Xaml code with usage ControlTemplates and VisualStateManager

As a matter of fact, at choice Location on a map it is displayed

 

<local:WeatherInfoItemTemplateSelector x:Name = "WeatherInfoItemTemplateSelector"

                                               BasicItemTemplate = "{StaticResource BasicWeatherInfoItemTemplate}"

                                               DetailedItemTemplate = "{StaticResource DetailedWeatherInfoItemTemplate}"/>

 

<DataTemplate x:Key = "BasicWeatherInfoItemTemplate">

 

<! - here in Styles.xaml it is defined ControlTemplate with name WidgetButtonStyle->

                                               <telerik:RadButton Style = "{StaticResource WidgetButtonStyle}"                                                       

                                               telerik:MapLayer. Location = "{Binding LocationInfo. Center}"

<! - here there is a binding to the output agent of the command from ViewModel  

         private void OnViewDetailsCommandExecuted (object obj)

 ->

                                               Command = "{Binding DataContext. ViewDetailsCommand, ElementName=RadMap1}"                                                                                          CommandParameter = "{Binding}"

                                               Tag = "{Binding DataContext, ElementName=RadMap1}">

 

<! - in Styles.xaml->

<Style x:Key = "WidgetButtonStyle" TargetType = "telerik:RadButton">

Defines a number of states and logical units of this already new control

<VisualStateGroup x:Name = "CommonStates">

                <VisualState x:Name = "MouseOver"> <! - displays a brief information->

 

Accordingly

<! - in Styles.xaml->

<Style x:Key = "DetailedPanelStyle" TargetType = "ContentControl">

                               <Setter Property = "VerticalAlignment" Value = "Center"/>

                               <Setter Property = "HorizontalAlignment" Value = "Center"/>

 

                               <Setter Property = "Template">

                                               <Setter. Value>

                                                               <ControlTemplate TargetType = "ContentControl">

<!-- Defines new Control displaying the detailed information

 

It is important to me to understand logical switching between states and interaction thus with ViewModel.

By pressing on telerik:RadButton Style x:Key = "WidgetButtonStyle" we pass in state XState

and thus through a binding to the trigger output agent OnXState from ViewModel is called

-->

 

I need to realise following behaviour in the program

1. To load map BingProvider

2. To display on a map sensors in the form of Circles  or ToolTip received of model EF4.0 through WCF or WCF RIA

3. The sensor has some measures

4. By pressing a sensor tag it is necessary to show RadGridView with current indications of sensors near the sensor on a map

5. It is necessary to display indications of several sensors in several RadGridView on a map

6. It is necessary to provide possibility to close the sensor indication

 

It agree with you, Andrey that example WeatherStation very difficult, but before me the simple task is put too not...

 

 

Please, once again I ask you to explain me the logic of transition between states at mapping

 

 

Thanks

Hello Elena,

Let me try to clarify some of the points you have:

1. To load map BingProvider
   This article reveals how to do the above. Note that you need to have a Bing Maps Key.
   
   
2. To display on a map sensors in the form of Circles or ToolTip received of model EF4.0 through WCF or WCF RIA.
   In order to display items on a RadMap, you need to have InformationLayer or DynamicLayer. The WeatherStation demo uses DynamicLayer. Since it derives from Telerik's ItemsControl, we have used ItemTemplateSelector to apply different DataTemplates to the items shown on the map (depending on the zoom level we show detailed or basic information). Feel free to use this approach should you need to display different information according to some factor.
   
   
3. By pressing a sensor tag it is necessary to show RadGridView with current indications of sensors near the sensor on a map
   You can use a Popup or RadWindow for this.
   
   
4. It is necessary to display indications of several sensors in several RadGridView on a map
   Once these several RadGridViews are items of a Dynamic/Information Layer, this should come out of the box.

Hope this helps. Let us know in case you have further queries.

Hi Elena,

Thank you for your reply.

From what I manage to catch reading the automatic translation, your main concern is how you switch different DataTemplates/Styles of data displayed on the map. Here is how this works in the WeatherMonitor application:

1. The RadMap there uses DynamicLayer. 
2. The DynamicLayer derives from Telerik.Windows.Controls.ItemsControl control which has a ItemTemplateSelector property. It can be used to give different DataTemplates to different items. Here is the usage in the WeatherMonitor application:


As you see we use 2 DataTemplates and we assign them in the WeatherInfoItemTemplateSelector class:



Another way to have various items on different zoom levels is to use Styles. See how you can do that in this example. 

Hope this leads you to the right direction. Let us know in case you need more support in the future.

Thanks for your advices Teodor!

 

You have helped me to write an application template of RadMap

I apply it

Correct that will consider it necessary

 

By this example for me 3 questions:

1 How to anchor a detailing window position to station control position on map

2 How to show loading indicator of the data in loaded in StationDataService

3 If it is a lot of measurements, and it is necessary to show only last actual 20-30,

    it is possible to think up that what property and the main thing as it to load in WCF RIA?
