Show Coordinates in Map Legend converted to other projection system

[Manfred]

Hi there,

can anyone give me a short descritpion, how to change the map legend where the current coordinates are displayed to an other projection system?

We do this:
our collegues send some coordinates, we transform them to show the point in our map.
But we want the to show the coordinates he send in the legend.
A short example how to do that would be fine.

Best Regards
Manfred

Hello Manfred,

The MapLegend is a specific control which is designed for using with colorizer only. So, you can't use it to display coordinates.

It seems you mean the MapMouseLocationIndicator (Mouse Position Coordinates or Mouse Location control) which is described in documentation at the following links:
http://www.telerik.com/help/silverlight/radmap-visual-structure.html
http://www.telerik.com/help/silverlight/radmap-features-mouse-location.html

Unfortunately this control supports displaying location using the Number format or using the Geographical format only. It does not support displaying location in different projection systems. So, you should disable it in RadMap with setting the MouseLocationIndicatorVisibility to "Collapsed" and you should create you own implementation of control like the MapMouseLocationIndicator. You can use the RadMap.MouseMove event to get the current mouse location.
The sample code is below.

                        MouseMove="radMap_MouseMove"
                        Center="40,-100"
                        ZoomLevel="5">

                <telerik:OpenStreetMapProvider />
            </telerik:RadMap.Provider>
        </telerik:RadMap>
        <Border HorizontalAlignment="Left" VerticalAlignment="Bottom"
                Width="220" Height="22"
                Margin="20,0,0,20"
                Background="#ffafafaf"
                BorderBrush="Black"
                BorderThickness="1"
                CornerRadius="5">
            <TextBlock x:Name="mouseLocator"
                       TextAlignment="Center"
                       Padding="0,3,0,0"/>
        </Border>
    </Grid>
</UserControl>

 

using System.Windows.Controls;
using System.Windows.Input;
using Telerik.Windows.Controls;
using Telerik.Windows.Controls.Map;

namespace CustomMouseLocator
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void radMap_MouseMove(object sender, MouseEventArgs e)
        {
            RadMap map = sender as RadMap;
            if (map != null)
            {
                Location mouse = Location.GetCoordinates(map, e.GetPosition(map));
                this.mouseLocator.Text = this.LocationToString(mouse);
            }
        }

        private string LocationToString(Location mouse)
        {
            // TODO: should implement convertion to string format of required coordinate system
            return mouse.ToString();
        }
    }
}
