Hi,
If you want retrieve information when you clicked on the map, you use this code:
Code Snippet
// Create new instance
SharpMap.Map _map = new SharpMap();
// create new layer
SharpMap.Layers.VectorLayer _layer = new SharpMap.Layers.VectorLayer("My Layer");
// set datasource to shape file
_layer.DataSource = new SharpMap.Data.Providers.ShapeFile("shape.shp");
// get position where mouse clicked
SharpMap.Geometries.Point clickPoint = _map.ImageToWorld(new PointF(e.X, e.Y));
// create new dataset
SharpMap.Data.FeatureDataSet ds = new FeatureDataSet();
// open DataSource
((SharpMap.Layers.VectorLayer)_map.Layers[0]).DataSource.Open();
// retrieve information from clicked point...this method fill dataset
((SharpMap.Layers.VectorLayer)_map.Layers[0]).DataSource.ExecuteIntersectionQuery(clickPoint.GetBoundingBox(), ds);
// close datasource
((SharpMap.Layers.VectorLayer)_map.Layers[0]).DataSource.Close();
if (ds.Tables.Count > 0)
{
StringBuilder str= new StringBuilder();
DataTable dt = ds.Tables[0];
foreach (DataRow r in dt.Rows)
{
str.Append(r["name_of_column"].ToString());
}
}
