Hi everyone!

I'm creating a workflow with Geocortex Workflow Designer the takes some inputs and with a query task get some features. 

I get the fratures and than i want to zoom map over these features. 

how can i do that?

i've try with set map extent, is that the right way?, SetMapExtent ask as parameters the properrty Extent of an envelope object, to get this envelope may i use get geometry or GetFeatureSetExtent? 

i need to run the external command ZoomToEsriFeatureSet? 

Can anyone help me please?

thank's for attention

  One way is to use a Set Map Extent activity. For the "Features" input, just put $query.results... It should be ok.

  Yes, but SetMatExtent require as input an object of type ESRI.ArcGIS.Client.Geometry.Envelope.

  How can i get this from a Query task that rpovide a ESRI.ArcGIS.Client.Tasks.Featureset object?

  Hi Fillippo,

  This is possible using a featureSet that is output from a query, you will need to include a 'GetFeatureSetExtent' activity after the query and before the SetMapExtent activity with the input as the featureSet output from the query.

  N.B. you can include the expand function - .expand in your SetMapExtent activity in order to show a larger area than just the queried feature.

  Also, if your queried feature is a point not a polygon or a line you would need to include a cast activity in order to give your point feature an envelope to be zoomed to.

  I hope that helps,

  Thanks,

  Harry

  Thanks @Harry Sturley? .

  If someone is like me wondering about how to use .expand.
