Hi srini,

You can bind items source of the information layer to the collection of the locations. You can find an example here:

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

To show line between 2 locations on the map you can use MapLine object:

Location loc1 = new Location(20, 20);
Location loc2 = new Location(40, 40);
MapLine line = new MapLine()
{
    Point1 = loc1,
    Point2 = loc2,
    Stroke = new SolidColorBrush(Colors.Red),
    StrokeThickness = 2
};

this.informationLayer.Items.Add(line);

Pay attention, if your information layer is bound to the collection of the locations then you should use second layer to show lines.

Kind regards,

Hi

 I have binded the radmap with muiltiple lat & long value it is working fine,i am using  bellow code to draw line in between two location  on radmap  it is also working fine . i want to draw a dotted line between to locations, how to do this?

 

 

 

private LinearGradientBrush CreateLinearGradientBrush(Location location1, Location location2)

 

{

 

 

Point point1 = location1.GetPoint(this.radMap);

 

 

 

Point point2 = location2.GetPoint(this.radMap);

 

 

 

var fill = new LinearGradientBrush();

 

fill.StartPoint =

 

new Point(0, 0);

 

fill.EndPoint =

 

new Point(point2.X - point1.X, point2.Y - point1.Y);

 

 

 

double max = Math.Max(Math.Abs(fill.EndPoint.X), Math.Abs(fill.EndPoint.Y));

 

fill.EndPoint =

 

new Point(fill.EndPoint.X / max, fill.EndPoint.Y / max);

 

 

 

if (fill.EndPoint.X < 0)

 

{

fill.StartPoint =

 

new Point(-fill.EndPoint.X, fill.StartPoint.Y);

 

fill.EndPoint =

 

new Point(0, fill.EndPoint.Y);

 

}

 

 

if (fill.EndPoint.Y < 0)

 

{

fill.StartPoint =

 

new Point(fill.StartPoint.X, -fill.EndPoint.Y);

 

fill.EndPoint =

 

new Point(fill.EndPoint.X, 0);

 

}

 

 

return fill;

 

}

 

 

private void SetLinearGradientBrushStops(LinearGradientBrush fill, Color startColor, Color stopColor)

 

{

 

 

var stop = new GradientStop();

 

stop.Color = startColor;

stop.Offset = 0;

fill.GradientStops.Add(stop);

 

 

var stop1 = new GradientStop();

 

stop1.Color = stopColor;

stop1.Offset = 1;

fill.GradientStops.Add(stop1);

}

Thanks in Advance

Hi,

You need to set the StrokeDashArray as follows:

StrokeDashArray = new DoubleCollection {2,2};
