Re: [mapguide-users] change layer definition runtime
Hi, Have you experience that after doing this update of layer using ajax and redraw a couple of time. Mapguide server breaks? because i suddenly get session expired or magguide server is not responding.. Im on the site the whole time and doing switching of layers to stress test it. But suddenly it turned pink and got that message reload map and got that error.

Re: [mapguide-users] change layer definition runtime
Hi, Back again, was able to make it work before with MapGuide 2.6.1 32bit now upgraded to 3.1.0 64bit.. Same code with changing layer at runtime.. funny thing now, nothing happens, but if select something on the map, it throws an error inside fusion-compressed.js, 'layerName' does not exists. From the c# code layers.remove(layer) it did work it seems that the layer was really removed on the map.. but the mapwidget itself didnt refresh to the new layer, it still looks the same. did call the command. mapWidget.redraw, mapWidget.reloadMap(). but nothing happens. Tried almost everything but its not working at all.. Is there something that i missed on the code? -- View this message in context: http://osgeo-org.1560.x6.nabble.com/change-layer-definition-runtime-tp5284382p5317071.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users

The layer definition is a xml where you can modify all atributes, including featuresourceid , featureclassname, etc. Debug the code and examine the string xml layer read in the set filter method. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/change-layer-definition-runtime-tp5284382p5285095.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users

Re: [mapguide-users] change layer definition runtime
You have to refresh the map using javascript.
Put in UtilMap class:
///
/// Refresh the Map in the Client using JavaScrit
///
/// Page Object calling this method
public void RefreshMapClient(Page objPage)
{
try
{
string strScript = "";
strScript += "" + "\r\n";
// Detect if the page has ScriptManager
if (System.Web.UI.ScriptManager.GetCurrent(objPage) == null)
objPage.ClientScript.RegisterStartupScript(objPage.GetType(),
"RefreshMapClient", strScript, false);
else
System.Web.UI.ScriptManager.RegisterStartupScript(objPage,
objPage.GetType(), "RefreshMapClient", strScript, false);
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
Put in the your page server-side, after setting the filter layer:
objUtilMap.RefreshMapClient(this);

Re: [mapguide-users] change layer definition runtime
Solved the error. I should be getting the mapname from the mapdwiget. Now there is no error. But it looks like i need to refresh fusion mapwidget for the layers to effect. Only thing now i think is to refresh the mapwidget for the layers to take effect. But it seems that layerTemp.ForceRefresh(); wont refresh the widget. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/change-layer-definition-runtime-tp5284382p5284847.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users

Re: [mapguide-users] change layer definition runtime
Hi, I have created layer definition from each maps on Maestro and just 1 MapDefinition, What i am trying to do is the just updated the layerdefinition of the mapdefinition to the specific selected map. I wanted to do it runtime. I cam currtently using fusion, is this possible to do on JS or just .net? And how? i am quite stuck now. Also another option for me to do is the create mapdefinition on runtime, but still no success on doing this. Any help will do.

Re: [mapguide-users] change layer definition runtime
You have to manipulate MgMap/MgLayer objects, so you have to use a server-side script. It doesn't have to be .net. It could be in Java or PHP. But it has to be one of the 3 languages which can work with the MapGuide Web API. Your script needs to take in mapname/sessionid and do the following: - Opens the MgMap from the mapname - Finds the matching MgLayer in the map's layer collection by its layer name - Make a new MgLayer that points to your new layer definition - Replace the matching MgLayer with your new MgLayer - Insert the new MgLayer to the layer collection at the matching index of the old MgLayer - Remove the old MgLayer from the layer collection - Save the map state and trigger a map refresh back on the client-side - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/change-layer-definition-runtime-tp5284382p5284422.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
