Hi List,
I have played a little bit with GeoExt and figured out that you can remove
Records from the Store to remove the Features from the map.
store = new GeoExt.data.FeatureStore({
layer: vecLayer,
fields: [
{name: 'name', type: 'string'},
{name: 'id', type: 'string'}
],
proxy: new GeoExt.data.ProtocolProxy({
protocol: new OpenLayers.Protocol.HTTP({
url: "point.asp", // this is due to IIS
format: new OpenLayers.Format.GML()
})
}),
autoLoad: true
});
Now I'm creating a new Layer, applying a filter to the old Store and
creating a new Store
tmpLayer = new OpenLayers.Layer.Vector("Vector 2");
store.filter('id', 'value', true, true);
tmpStore = new GeoExt.data.FeatureStore({
layer: tmpLayer
});
To remove some Records from the Store
for (i = 0; i < store.getCount(); i++) {
var record = store.getAt(i);
tmpStore.add(record);
}
Does anybody has a better solution. It's working but I have some trouble
with the eventListeners when selecting Features.
Best regards,
Mario
