‘Non editable’ Layers are those that are connected to any data source through a ‘read only’ data Provider
The reason why these layers are deemed ‘non-editable’ is that, since the data sources connected can not be saved if their content in a Map is changed, the application prevents you from deleting Features or modifying data in the Data grid or editing their Fields
To carry out any of these editing operations on a ‘non editable’ Layer, for example deleting some of its Features, we need to ‘Disconnect’ the Layer from its data source, so that its content will be stored in the Map and will become an ‘editable’ Layer
You cannot undo this operation so you should avoid saving the original Map. It is recommended to save the modified Map using another name or into another location
