Hide map pins.

[Mark]

I am using dynamic layers to retrieve data depending on the zoom level and it's working great. However, the user would like to be able to hide certain map pins by checking a show/hide checkbox on the form.

Is it possible to hide items on a dynamic layer? Or even set the visibility of the layer?

I did think about refreshing it's datasource but I cannot find a way to force the map to rebind, I could move the map center programmatically which would cause the ItemsRequest to fire but that seems like a hack.

Is there a way to force a rebind of the data or hide the pins?

Many thanks,
Mark

Hi Mark,

You can change the visibility of the layer using the DynamicLayer.Visibility property.
When you want to reload the data on the layer then you can invoke the DynamicLayer.Refresh method.

Calling Refresh causes all items to flash. Is there a way to refresh dynamic layer without flashing? (similar to the way information layer items don't flash if you change visibility of one or more items)

Hello Sergey,

Unfortunately it is not possible. When refreshing the DynamicLayer removes all existing items and reloads them.
