[mapguide-users] Features Are Not Highlighted

[Ivan Milicevic]

Hello,

 

You need to refresh mapFrame.

 

Look at this:

 

1.       Put this in head of file

<script type="text/javascript">

function select(xml)

{

        parent.mapFrame.SetSelectionXML(xml);

        parent.mapFrame.ZoomSelection();   

}

</script>

 

...and this at the end of file...

 

    map.Save();

 

    RegisterStartupScript("start", "<script>select('" + selectionXml +
"');</script>");

Subject: [mapguide-users] Features Are Not Highlighted

 

Hi,

 

I have written the following code to select/highlight the features on
the map.

 

        MgMap map = new MgMap(myConnection);

        map.Open("MyMap");

        MgFeatureQueryOptions queryOptions = new
MgFeatureQueryOptions();

        queryOptions.SetFilter("ID<4");

        MgLayer layer = map.GetLayers().GetItem(0) as MgLayer;

        MgFeatureReader featureReader =
layer.SelectFeatures(queryOptions);

        MgSelection selection = new MgSelection(map);

        selection.AddFeatures(layer, featureReader, 0);

        selectionXml = selection.ToXml();  

 

The code runs perfectly. And in viewer it also shows that 2 Features
Selected. But features are not highlighted on the map.

Please assist...

 

Thanks & Regards,

Ravinder
