How to update annotation in Maps at run time?

Platform: WinForms |
Control: Maps
Tags: maps, annotation

Annotations in WinForms maps can be used for both static and dynamic cases. When dynamically adding annotations, layers must be updated and refreshed for the changes to reflect in the maps as demonstrated in the following code sample.

Code sample

private void button1_Click(object sender, EventArgs e)
            maps1.Layers[0].Annotations.Add(new Annotation() { AnnotationShape = AnnotationShapes.Rectangle, AnnotationLabel = "Brazil",
                Latitude = -15.7833, Longitude = -47.8667


Sample for using annotation in both static and dynamic cases: http://www.syncfusion.com/downloads/support/directtrac/general/ze/MapAnnotationWF-463127546
