How to target compilers in PS?

If PS is targeting any other compiler than you need then simply change the compiler directory to make sure it compiles with correct version of .NET.

E.g.

cd 'C:\WINDOWS\Microsoft.NET\Framework\v3.5'
.\csc /t:library 'C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\generatedClient.cs'  /r:"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0\System.ServiceModel.dll"

Javascript events for ASP.NETcontrols

While using Java Script events with ASP .NET controls make sure that they are really JS events. E.g.
OnSelectedIndexChanged and OnTextChanged are server side events. If you try to use them from client side then they will not fire. In such case you need JS 'onchange' event.
