Identify task without click

BrianGustafson — Fri, 09 Jul 2010 13:43:36 GMT

Is there a way to run an identify task without the user clicking on the map? I have tried creatting a point from lat\longs and then putting that in the geometry property of the parameters but it returns no results. I also tried creating Map.Mouseevent and putting that in the geometry and that did not work either. Has anyone tried this?

Yes this should work. Did you set the spatial reference on the point you created?

This is the code I am using. It is the same code from when the click event is fired on the map. the click event works and the one below does not. The lat\longs of the click and the input are the same.

//run identifytask for selected station to get the data to populate the datagrid
            IdentifyTask identifyTask = new IdentifyTask("http://arcgisd/ArcGIS/rest/services/Facilities/MapServer");//fix
            identifyTask.ExecuteCompleted += IdentifyTaskPostEdit_ExecuteCompleted;
            identifyTask.Failed += IdentifyTask_Failed;

            IdentifyParameters identifyParameters = new IdentifyParameters();
            identifyParameters.LayerOption = LayerOption.all;
            identifyParameters.Tolerance = 20;

            //Pass current Map properties to identify parameters
            identifyParameters.MapExtent = MyMap.Extent;
            identifyParameters.Width = (int)MyMap.ActualWidth;
            identifyParameters.Height = (int)MyMap.ActualHeight;

            //Identify features at the click point
            identifyParameters.LayerIds.Add(0);
            identifyParameters.SpatialReferenceWKID = MyMap.SpatialReference.WKID;
            Map.MouseEventArgs mousecords = new Map.MouseEventArgs();
            mousecords.MapPoint = new MapPoint();
            mousecords.MapPoint.X = dLongX;
            mousecords.MapPoint.Y = dLatY;
            mousecords.MapPoint.SpatialReference = MyMap.SpatialReference;

            identifyParameters.Geometry = mousecords.MapPoint;

            identifyTask.ExecuteAsync(identifyParameters);
