Can I use radio button to change layers in the same map service?

Question

Hi all,

I had different layers published using one map service and I want to use radio button to switch layers. I noticed from ESRI's sample (http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#SwitchMap) that radio button can be used to switch layers between different map services. I am wondering if I can switch layers in one single map service. I tried...but didn't get the good results. Do anyone use such thing before? Any suggestion? Thank you:)

Hello,

I am trying to do something similar but I am completely stuck. Maybe if you would be willing to take a look at my forum post to see if you can point me in the right direction I would greatly appreciate it.

I assume by "change layers" you mean toggling between invisible and visible layers.  First you have to have the layer on your map as a Dynamic layer.  Second every layer you want to change between must be in the service.

Then just create your check event for the radio buttons.  In that event you can connect to your service layer which will have a VisibleLayers property which is an integer list of all the visible layers.  Set only the ones you want.

Good Luck

Hi Brent,

Thank you very much! That works very well! I use the setvisibility method to set visibility for a particular layer. 🙂
