[mapguide-users] Re: Is it Possible to set Feature Label for a layer dynamically

[SriRam007]

Thank u very much to both of u 
Kenneth Skovhede, GEOGRAF A/S  And zspitzer 

Really u both helped me a lot. Specially Kenneth Skovhede

And here is the Full and Final Code

Everyone can use it

        Utility.InitializeWebTier(Request);
        string myLayerName = ddlLayer.SelectedItem.Text.ToString();
        //args = Utility.GetRequestParameters(Request);
        //Query Qry = new Query(args);

        MgUserInformation userInfo = new
MgUserInformation(Session["ID"].ToString());
        MgSiteConnection siteConnection = new MgSiteConnection();
        siteConnection.Open(userInfo);
        MgResourceService resourceService =
siteConnection.CreateService(MgServiceType.ResourceService) as
MgResourceService;
        //MgFeatureService featureService =
siteConnection.CreateService(MgServiceType.FeatureService) as
MgFeatureService;
        MgMap map = new MgMap();
        map.Open(resourceService, "Sheboygan");//For "Sheboygan" Replace
Utility.GetParameter(this.args, "MAPNAME")

        MgLayerCollection layers = map.GetLayers();
        ArrayList layerNames = new ArrayList();
        MgLayer layer = Utility.GetLayerByName(map, myLayerName);
        string s = layer.GetLayerDefinition().ToString();

        MgResourceIdentifier resId = new
MgResourceIdentifier(layer.GetFeatureSourceId());
        MgResourceIdentifier layerDefResId = layer.GetLayerDefinition();
        MgByteReader byteReader =
resourceService.GetResourceContent(layerDefResId);

        string layerDefinition = ReplaceXMLValue(byteReader);

        MgResourceIdentifier layerResId = new
MgResourceIdentifier("Session:" + Session["ID"].ToString() + "//" +
myLayerName + ".LayerDefinition");
        MgByteReader reader = new MgByteReader(layerDefinition, "text/xml");
        resourceService.SetResource(layerResId, new
MgByteReader(layerDefinition, "text/xml"), null);
        layer.SetLayerDefinition(layerResId, resourceService);
        map.Save(resourceService);

But I want to modify that MapDefinition  
and I want the changes should be done permanently not only until the end of
the session.
Ok any way At first let me go through some sites and this forum about
MapDefinition. If still not getting anything  I will ask u again.

thank u very much...
