I am using Nokia Lumia 520. I need to control downloading application updates. When i connected in WiFi, i started downloading updates(partially completed).

Windows Phone 8.1 will allow the user to explicitly pick the following:
Option to update store apps when only on Wi-Fi
The above is listed as a feature available in the Windows Phone 8.1 preview to developers.
There's an article on the how-to section of the Windows Phone website, namely How can I minimize my data usage?. The article gives several tips and this one might be helpful to you:
Prevent cellular data usage when Wi-Fi connectivity is limited
If your phone is connected to a Wi-Fi network and can't complete a task because connectivity becomes limited, you can determine whether or not your phone will use cellular data to finish the task. For more info, see Cellular settings.
- In the App list, tap Settings > Cellular.
- Tap For limited Wi-Fi connectivity, and then tap Don't use cellular data.
This setting may not appear on your phone, depending on how your phone is set up by the manufacturer or your mobile operator.
To have this setting, your phone must be running Windows Phone software version 8.0.10211.204 or later. See How do I update my phone software? for more info about how to update your phone.
