First, thanks to those people who sent useful suggestions a couple of months ago - when we have everything worked out we'll publish a summary. We're still having trouble with selecting features and making new layers at acceptable speeds, but more significantly our problem is now to attach attribute data to selections of features (we can do it fine for a whole table). My understanding is as follows: Layer.Add basically adds the graphical objects (.map file etc.) in a MapInfo table to the map component, but not the textual (attribute) data held in the .dat or .dbf file. Datasets.Add binds the attribute data to the graphical objects, making them behave like a MapInfo table. The behaviour of the binding can be controlled with a BindLayer object. Binding is very straightforward if you are simply binding the attribute data from a MapInfo table with the graphical objects in the same table - no need to specify a bindlayer object, it just does a 1:1 bind. Binding is relatively straightforward if you have X and Y coordinate data - you just specify reference columns. Our problem is that we have performed a query to create a _feature collection_. We then add this feature collection to a (new) map layer. Following from what I've said above, all that goes across is the graphical objects devoid of their attrribute data, so now we need to bind the attribute data. QUESTION: How do we bind the attribute data for the selected features (which are polygons, not points) to the graphical objects in the feature collection/new file? Any help would be appreciated.
