Example
This example demonstrates how to obtain a collection of layers supported by the Web Map Service.
To do this, use the WmsDataProvider.ResponseCapabilities event arguments to obtain the CapabilitiesRespondedEventArgs.Layers collection.
using DevExpress.XtraMap;
using DevExpress.XtraTreeList;
using System;
using System.Linq;
using System.Windows.Forms;
namespace WmsDataProviderExample {
public partial class Form1 : Form {
ImageLayer WmsLayer { get { return mapControl.Layers["WmsLayer"] as ImageLayer; } }
WmsDataProvider Provider { get { return WmsLayer.DataProvider as WmsDataProvider; } }
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
// Specify a server URI.
Provider.ServerUri = "http://INSERT_YOUR_SERVER_URI";
// Handle the ResponseCapabilities event.
Provider.ResponseCapabilities += OnResponseCapabalities;
}
void OnResponseCapabalities(object sender, CapabilitiesRespondedEventArgs e) {
tlLayers.DataSource = e.Layers;
}
private void OnGetCellValue(object sender, VirtualTreeGetCellValueInfo e) {
WmsLayer layer = e.Node as WmsLayer;
if (layer == null) return;
if (e.Column.FieldName == "LayerName") {
e.CellData = layer.Title;
}
}
private void OnGetChildNodes(object sender, VirtualTreeGetChildNodesInfo e) {
WmsLayerCollection layers = e.Node as WmsLayerCollection;
if (layers != null) {
e.Children = layers.ToList();
}
WmsLayer layer = e.Node as WmsLayer;
if (layer != null) {
e.Children = layer.Children.ToList();
}
}
private void OnFocusedNodeChanged(object sender, FocusedNodeChangedEventArgs e) {
WmsLayer layer = tlLayers.GetDataRecordByNode(e.Node) as WmsLayer;
if (layer == null) return;
Provider.ActiveLayerName = layer.Name;
mapControl.ZoomToRegion(layer.LeftTop, layer.RightBottom, 0.15);
}
}
