I'm using RadComboBox with loadondemand in my page.on clientselectedindexchanged of combo1, I call clientitemrequesting of combo2 and then fill it with my webservice. after I move to dot net 4 and IIS7, after item selected change of combo1, it show me the error "call to method failed".
I think this is for some limitations on IIS7 but don't know what service must activate in IIS.
is there any one familiar with this or have any idea?

I found the solution:
1- Must enable dotnet4 ISAPI filter on ISAPI&CGI Restriction on IIS
2- must ReInstall the dot net 4.
now every things work correctly
