Re: [mapguide-users] Trying to create an ajax search thingo

Thanks for the heads up!

That makes things a lot neater :)

Hopefully I can make this available for some commenting when I'm all done :)


Also, you may need to double check that you're correctly using the MgMap API
as a result of http://trac.osgeo.org/mapguide/wiki/MapGuideRfc9

I can remember seeing somewhere something taht returns all the mapped feature
properties from the layer, however I can seem to remember what it was
attached to

FeatureReader? LayerDefinitoin? MgSelection?

That would be the Layer Definition. You would have to get the resource id of
the layer definition from the MgLayer and get the resource content, looking
for the PropertyMapping elements (I believe).

2009-04-28 Thread Jamo 

Jackie I've created a monster..

something is wrong with the FeatureReader that is produced from the layer
 i think?

It seems to be retrieveing all features from the featuresource  the
layer has a filter assigned that grabs only some features from the
featuresource...
If you or anyone is able to have a looky it would be great ! requires
ajaxcontroltoolkit.
I can zip up the project if required and post it here.

Perhaps you may have used the wrong MgSelection constructor? The API docs
says that MgSelection() is a dummy constructor.

 I'm trying to populate an Ajax TabContainer with a tab for each search.
 
 I'm getting an error for line 94: The map definition is invalid. 
 
 foreach (MgLayer cLayer in cadFeatures.GetLayers())
 
 Is it best to store the information needed for each search in a
 MgSelection or would it be better to extract information needed to a
 DataTable? I'm trying to make it as flexible as possible. hopefully
 adding some other search type other than just DropDownList.
 
 At the moment this runs seperate to mapguide and does not interact with
 the map itself (just for testing at the moment).

Re: [mapguide-users] Trying to create an ajax search thingo

2009-04-27 Thread Jamo 

Cheers Jackie I've fixed it up changed the MgSelection to MgSelectionBase
where needed.

Also changed the
MgSelection thisSel = new MgSelection() to MgSelectionBase thisSel = new
MgSelectionBase(map); which i think has fixed up the issue

Another issue thats got me stunned is this doesn't work..
foreach (MgLayerBase cLayer in cadFeatures.GetLayers())
{
  Response.Write(cLayer.GetClassDefinition().GetProperties().Count);
}
However at the same point in code this does?

  string layerClassName = cLayer.GetFeatureClassName();
  string selectionString = cadFeatures.GenerateFilter(cLayer,
layerClassName);
  string layerFeatureId = cLayer.GetFeatureSourceId();
  MgResourceIdentifier layerFeatureResource = new
MgResourceIdentifier(layerFeatureId);
  MgFeatureQueryOptions queryOptions = new MgFeatureQueryOptions();
  queryOptions.SetFilter(selectionString);
  MgFeatureReader featureReader =
FeatureService.SelectFeatures(layerFeatureResource, layerClassName,
queryOptions);
 
Response.Write(featureReader.GetClassDefinition().GetProperties().Count);

I'm not too sure on why or how but I'm not too fussed unless this extra
creation of a MgSelection Set will cause twice as much waiting
