Exception while adding layers without a text/name

Hi,

An exception is thrown while adding layers without name. (System.InvalidOperationException: 'A layer with the same Name already exists in the collection.')

i.e

var layer1 = new MapLayer();
var layer2 = new MapLayer();

map.Layers.Add(layer1);
map.Layers.Add(layer2);

The simple fix is to always pass a unique name, but it must work like say DataTable.Columns.Add(); (which internally generates unique name)

Thanks

Hi, Ketan,

Yes, there is a parameterless constructor for the MapLayer which allows you to add multiple layers without a name. That is why I previously logged this as a request for improving.

Please make sure that you follow this item in order to get notified for any further changes.

Hi Dess,

The MapLayer constructor accepts null for the 'name' parameter.

Hello, Ketan,

Currently, each MapLayer requires a unique name by which it can be accessed and managed further, e.g. adding pins to it. The first layer can be added with an empty name, but it is expected the second MapLayer without a name to thrown an exception since the name is not unique, there is another layer already with the same empty name.

Indeed, it sounds reasonable to generate an automatic name for the layer if it is added with an empty name. That is why I am converting this support thread into a public feedback item on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
