MouseOver Map

[Dharmesh Trivedi]

I would like to put  a push pin in the map and when a mouse hover show detail for that push pin (e.g. contact name, address , phone etc) for that state.

Hi Dharmesh Trivedi,

To do this you need to add a freamwork element to the map information layer and set the map location as an attached property. You can see how this is done in this example: http://demos.telerik.com/silverlight/#Map/Integration/MapPieChart

You can then do whatever you want with the mouse over event of that FrameworkElement etc. You can even put a control there (like in our example).

Hi Arvind Dhasmana,

Please see the Items Virtualization example.
http://demos.telerik.com/silverlight/#Map/DynamicLayer
The example uses different styles (colors) for items depending on the data. It uses the ContentControl element with different Control Templates. So, you can use any shapes inside the template.
You can attach the mouse enter and mouse leave events to the element you add to the layer.
Please look at the DataServiceGetStoresCompleted method of the Example.xaml.cs (it contains the code that attaches the mouse events). Then you can show or hide popup when the events occur.

The example uses WCF service to retrieve items that are displayed on the map. You can look at source code of service on your PC using the following path:
 C:\Program Files\Telerik\RadControls for Silverlight Q1 2010\Demos\ExamplesWeb\RadMapDataService.svc.cs
You don't need to use kml. You can create a WCF service that will retrieve data from your DataBase.

Hello Arvind Dhasmana,

You can simply use a standard Tooltip control as popup. You can specify it in the control template and bind to the data you'd like to show. For example:

<ControlTemplate x:Key="marketTemplate" TargetType="ContentControl">
    <Grid Width="30" Height="30" layer:MapLayer.Location="{Binding Path=Location}">
        <ToolTipService.ToolTip>
            <ToolTip>
                <ToolTip.Content>
                    <Border BorderBrush="Red" BorderThickness="2" Background="#7FFFFFFF">
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto" />
                                <RowDefinition Height="Auto" />
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition Width="Auto" />
                            </Grid.ColumnDefinitions>

                            <TextBlock Grid.Row="0" Grid.Column="0"
                                Foreground="Green" Text="Name:" />
                            <TextBlock Grid.Row="0" Grid.Column="1"
                                Foreground="Brown" Text="{Binding Path=Title}" />

                            <TextBlock Grid.Row="1" Grid.Column="0"
                                Foreground="Green" Text="Description:" />
                            <TextBlock Grid.Row="1" Grid.Column="1"
                                Foreground="Brown" Text="{Binding Path=Description}" />
                        </Grid>
                    </Border>
                </ToolTip.Content>
            </ToolTip>
        </ToolTipService.ToolTip>
        <Ellipse Width="30" Height="30">
            <Ellipse.Fill>
                <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                    <GradientStop Offset="0" Color="#4F009F00" />
                    <GradientStop Offset="0.3" Color="#7F00CF00" />
                    <GradientStop Offset="0.5" Color="#FF00FF00" />
                    <GradientStop Offset="0.7" Color="#7F00CF00" />
                    <GradientStop Offset="1" Color="#4F009F00" />
                </LinearGradientBrush>
            </Ellipse.Fill>
        </Ellipse>
    </Grid>
</ControlTemplate>

Set your data object as DataContext to the content control and bind texts in the tooltip to the fields in your data object.

Hi

Thanks for your reply

Now after doing this i also want to divide my map in given regions using this same dynamic layer concept and dividing the data into regions.
e.g : - US states are divided into 8 ISO regions.So i want these region should have boundary defined How this can be achieved.

You have given this region example againg with kml files only.

Is it possible to do it without that .


Please reply ASAP.

Hello Charu,

The dynamic layer does not work with ISO regions. It uses the rectangular areas which divides the world map like a grid.

If you just want to show some regions without using KML, then you can use the MapPolygon class instances directly. Also you can use an information layer to show them once separately from the dynamic layer.
Please see the following sample code:

<map:RadMap x:Name="RadMap1"
            Center="40,-100"
            ZoomLevel="4">
    <layer:InformationLayer x:Name="informationLayer" />
</map:RadMap>

private void AddPolygon()
{
    var points = new LocationCollection
    {
        new Location(43, -122),
        new Location(40, -93),
        new Location(37, -111),
        new Location(33, -115),
        new Location(43, -122)
    };

    var polygon = new MapPolygon()
    {
        Points = points,
        Stroke = new SolidColorBrush(Colors.Brown),
        Fill = new SolidColorBrush(Color.FromArgb(128, 55, 77, 99)),
        StrokeThickness = 1
    };

    informationLayer.Items.Add(polygon);
}

Hi

Thanks a lot for your reply :).It is working now
Query :
if i want to divide US into ISO regions with kml file then how many files i have to include in my code.

Hi Charu,

The KML format allows to have multiple polygons in a single file. So, it will be enough to use a single one.

All the best,

Hi

1) I need the output as it is in "EmptyProvider" of your demo but you have hardcoded here the population range and i want to read the Name of the State through that kml file is it possible if yes how?? Because you are taking the framework element that is giving me only coordinates of map polygon not the name .

2) My Project has multiple xap files , But i am not able to read the " file "xml" it is giving me null alwaz

"

 

 

StreamResourceInfo streamInfo = Application.GetResourceStream(

 

 

 

new Uri("/States/UsaSimplified.xml", UriKind.Relative));"

I have used this and it is giving me null  i am not able to find what is the path here it require

My solution structure is (Solution Name)A- > Modules ( Folder ) --> My Site Locator Module(Folder)-->Presenter(Folder) (where i load my file ) 

and my "UsaSimplified.xml" this file is in states folder of My Site Locator Module(Folder)
i.e presenter and states are in "My Site Locator Module Folder"

Please help
