Well I am not having much luck. I can't seem to retrieve my results from the GP Task. The GP Task runs fine and I do see the results in the jobs folder on the server. I then attempt to run a GetResultDataAsync to get the GPFeatureRecordSetLayer but it is getting hung up. It seems like my geoprocessorTask.GetResultDataCompleted is not firing as the completed or failed events never get triggered. Anyone see anything wrong in my code? This is the first time I try an Asynchronous request so there is verywell some user error involved here. I use the samples as a guide.
private void Geoprocessor_JobCompleted(object sender, JobInfoEventArgs e)
{
Geoprocessor geoprocessorTask = sender as Geoprocessor;
geoprocessorTask.GetResultDataCompleted += GeoprocessorTask_GetResultDataCompleted;
geoprocessorTask.Failed += GeoprocessorTask_Failed;
geoprocessorTask.GetResultDataAsync(e.JobInfo.JobId, "output");
}
private void GeoprocessorTask_GetResultDataCompleted(object sender, GPParameterEventArgs e)
{
GraphicsLayer graphicsLayer = MapApplication.Current.Map.Layers["MyResultGraphicsLayer"] as GraphicsLayer;
GPFeatureRecordSetLayer gpLayer = e.Parameter as GPFeatureRecordSetLayer;
MessageBox.Show(gpLayer.FeatureSet.Count().ToString());
foreach (Graphic graphic in gpLayer.FeatureSet.Features)
{
graphicsLayer.Graphics.Add(graphic);
}
MessageBox.Show(graphicsLayer.Count().ToString());
this.dg.GraphicsLayer = graphicsLayer;
btnPoint.IsEnabled = true;
}
private void GeoprocessorTask_Failed(object sender, TaskFailedEventArgs e)
{
MessageBox.Show("Geoprocessing service failed: " + e.Error);
btnPoint.IsEnabled = true;
}
