Here i have written code for enabling snapping point and line for the existing line.But its not working in my code.Its working for point without any issue. can u help me out in adding new functions or features added to the code.
webmap-->Group Layer-->Feature Layers
on Initialize i am calling the EnableSnapping();
private async void EnableSnapping()
{
// Ensure all feature layers within the map are loaded
foreach (var layer in mapView.Map.OperationalLayers)
{
await LoadLayerRecursively(layer);
}
// Synchronize the snap source collection with the map's operational layers.
_geometryEditor.SnapSettings.SyncSourceSettings();
// Enable snapping on the geometry layer.
_geometryEditor.SnapSettings.IsEnabled = true;
// Optionally, configure snap tolerance and other settings
_geometryEditor.SnapSettings.Tolerance = 10.0; // Adjust tolerance as needed
// Create a list of snap source settings with snapping disabled initially
List<SnapSourceSettingsVM> snapSourceSettingsVMs = new List<SnapSourceSettingsVM>();
// Iterate through the feature layers to set snapping for points and polylines
foreach (var snapSourceSetting in _geometryEditor.SnapSettings.SourceSettings)
{
if (snapSourceSetting.Source is FeatureLayer featureLayer)
{
var snapSourceSettingsVM = new SnapSourceSettingsVM(snapSourceSetting) { IsEnabled = false };
snapSourceSettingsVMs.Add(snapSourceSettingsVM);
}
}
// Populate lists of snap source settings for point and polyline layers.
var pointSnapSettings = snapSourceSettingsVMs.Where(snapSourceSettingVM => snapSourceSettingVM.GeometryType == GeometryType.Point).ToList();
var polylineSnapSettings = snapSourceSettingsVMs.Where(snapSourceSettingVM => snapSourceSettingVM.GeometryType == GeometryType.Polyline).ToList();
PointSnapSettingsList.ItemsSource = pointSnapSettings;
PolylineSnapSettingsList.ItemsSource = polylineSnapSettings;
// Debug: Print counts of point and polyline snap settings
Debug.WriteLine($"Point Snap Settings Count: {pointSnapSettings.Count}");
Debug.WriteLine($"Polyline Snap Settings Count: {polylineSnapSettings.Count}");
}
