Querystring and REST services

  Hi,

I have a custom list and visual webpart.

I am trying to use the REST services to fetch data from the custom list and showing it in various fields of visual webpart.

The  call to the webpart has a querystring variable. I am trying to get the data from the custom list based on this querystring.

Example: servername/sitename/_vti_bin/ListData.svc/CustomList is my current URL.

The call to visual webpart is like this: servername/sitename/sitepages/testpage?ItemID=01

If ItemID =01, then get the item which matches ItemID in the custom list.

How to change the REST url based on the querystring?

Thanks
