Hi Sean Jones,
Thanks for your reply.
Please find my scenario below.
We have created a relationship class between polygon feature class and standalone table. Due to this relationship, whenever we delete polygon – the associated entries from the table are also getting deleted.
But when we created a new polygon/ modify the existing polygon geometry – the corresponding records in the table are not getting updated.
to address this Modify geometry changes - i am trying to capture the vertex level events.
I have tried to use the "OnSketchModifiedAsync " virtual method now. But this method is not getting triggers for every vertex change. Please find the sample code snippet below.
internal class MapTool1 : MapTool
{
public MapTool1 ()
{
IsSketchTool = true;
SketchType = SketchGeometryType.Point;
SketchOutputMode = SketchOutputMode.Screen;
var systemCursor =System.Windows.Input.Cursors.Arrow;
Cursor = systemCursor;
}
protected override async Task<bool> OnSketchModifiedAsync()
{
MessageBox.Show("Entered into OnSketchModifiedAsync function");
await QueuedTask.Run(async() =>{
ActiveMapView.SelectFeatures(await GetCurrentSketchAsync());
var sketch = await GetCurrentSketchAsync();
var editOp = new EditOperation();
editOp.Name = "Edit Vertex";
editOp.SelectModifiedFeatures = true;
editOp.SelectNewFeatures = true;
MessageBox.Show(editOp.EditOperationType.ToString());
//ArcGIS.Desktop.Editing.Events.RowChangedEvent.Subscribe(onRowChangedEvent, featureLayer.GetTable());
//Execute the Edit Operation
// editOp.Execute();
//ArcGIS.Desktop.Editing.Events.RowChangedEvent.Unsubscribe(_rowChangedToken);
//ArcGIS.Desktop.Editing.Events.RowChangedEvent.Unsubscribe(_rowCreatedToken);
});
return true;
}
Here if i enable the RowChangedEvent subscription - whenever there is a change in the feature table - the method is getting triggered and ideally this will happen only once we finish the geometry changes. In this situation, to achieve my goal i have to run multiple geoprocessing tools to get the vertices information from polygon feature and then load into table. But this will not a suitable option for us, since we are having complex polygons with thousands of vertex (some times).
Please correct me, if i am doing any wrong here. or please suggest any other alternative way to achieve my goal.
Thank you.
