Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v24.2.dll
NuGet Package: DevExpress.Wpf.Map
#Declaration
public void UpdatePoint(
MapRuler ruler,
CoordPoint point,
int index
)
#Parameters
Name | Type | Description |
---|---|---|
ruler | Map |
The ruler in which to update a point. |
point | Coord |
Coordinates of the new ruler point. |
index | Int32 | The index of the ruler point. |
#Remarks
The example below creates a ruler to measure the distance between Paris, Milan and Vienna. After calculating this distance, the code updates the ruler as follows:
- a point is added at Berlin’s coordinates;
- the first point is moved from Paris to Dusseldorf;
- the point at Milan’s coordinates is removed from the ruler.
MapRuler ruler = mapControl1.Measurements.CreateRuler(RulerType.Distance,
new List<CoordPoint>() {
new GeoPoint(48.864716, 2.349014), // Paris
new GeoPoint(45.46427, 9.18951), // Milan
new GeoPoint(48.20849, 16.37208) // Vienna
});
//The code below updates the ruler.
mapControl1.Measurements.InsertPoint(ruler, new GeoPoint(52.520008, 13.404954), 2); // Berlin
mapControl1.Measurements.UpdatePoint(ruler, new GeoPoint(51.2217200, 6.7761600), 0); // Dusseldorf
mapControl1.Measurements.RemovePoint(ruler, 1); // Milan
