[mapguide-users] Zoom to selected feature with Fusion MGOS 2.1 Beta

[SMAmap Webmaster]

Thanks Mike, this is exactly what I wanted to do.  Many of my users are on
relatively slow connections so I want to do as little re-drawing as
possible.

That's what I was gong to suggest, but you can also set your initial map 
extents in the ApplicationDefinition file like so:

    <MapGroup id="gmapLL" xsi:type="MapType">
      <Map xsi:type="MapLayerType">
        <Type>MapServer</Type>
        <SingleTile>true</SingleTile>
        <Extension>
          <MapFile>/ms4w/apps/gmap/htdocs/gmapLonLat.map</MapFile>
          <LayerMetadata>wms_metadataurl_href</LayerMetadata>
        </Extension>
      </Map>
      <InitialView>
        <MinX>-71.8</MinX>
        <MinY>40.5</MinY>
        <MaxX>-42</MaxX>
        <MaxY>63.5</MaxY>
      </InitialView>
    </MapGroup>
