Hi Anatolii,

This is a good start to check FeatureDataGrid on silverlight sample:

Also this is the silverlight API about Datagrid

I need to work with mysql -table , wich contains x,y - data about events. I use arcgis 10.1 for server and desktop, visual studio 2012. When working with previous releases I formed shape file and refresh map (I use arcobjects). I know that in arcgis powerful tools to work with objects, but need to use the database SQL-server, ArcSDE   etc. Can I use these tools when working with mysql?

As I understand, it works with the map layer. Do I understand correctly that, in any case, to solve this problem it is necessary to create a layer in code-behind on the basis of x,y - table. There is no service that displays a selection of the table records with the specified symbol ?
  And by the way. How to create a layer from the selection of x,y - table?

[AnatoliiTerentiev]

Because shape file is locked  when  service is published, it is necessary to use ArcSDE or some of the SQL servers , when it is need to show x,y table with to enable adding records. Is it true?
PS. That is I can't use only mysql for this task?
