In codebehinde or js I need to select object and zoom to selected object. I use in JS:

     function SetSelectionXML(selectionXml) {
          var Fusion = window.top.Fusion;
          var mapWidget = Fusion.getWidgetById(mgApiMapWidgetId);
          if (mapWidget && mapWidget.isMapLoaded() && selectionXml.length > 170)  {
              mapWidget.setSelection(selectionXml, true);
              
          }
      }

But I have problem with zoom to selection object, because is zoomig to different place.

In loadMap.php have I also change code to:

$minScale = "5000";
$maxScale = 'infinity';  // as MDF's VectorScaleRange::MAX_MAP_SCALE
if($minElt->length > 0 && $minElt->length > 1)
        $minScale = $minElt->item(0)->nodeValue;

Can you please help me?

Tenx!

If you are using .NET you need to call a server side page sending the MAPNAME, SESSION, LAYER, and "where clause" to receive the XML of the selected features.  

You then use Javascript to take that XML to select the features and zoom to it.

Javascript:

var mapWidget = Fusion.getWidgetById('Map');

 mapWidget.setSelection(myXMLReturnedFromServer, true);

the "true" actually zooms to the selected featue.

In some of case, we want to "zoom to selection"; this "selection" is not by mouse click; it's by "enter an attribute value" or "by the calculation result which match some specific attribute column value". In this case we need an example how to use "setSelection: function(selText, ZoomTo) function, what is the input parameters?

You need the manually select the features programatically.  For example you want the road with an ID of 20

You pass the SESSIONID, MAPNAME, KEY (20), KEYNAME (ID), LAYER (ROADS)'

but you should use AJAX (try jQuery - http://api.jquery.com/jQuery.ajax/)

once the XML is returned from the page, you can call the javascript call

 mapWidget.setSelection(selectionXml, true);

The "TRUE" will zoom to selected (unless it is a point - AIMS 2013 and AIMS 2014 changed so it just pans to points now and doesn't zoom)
