In Share point 2010, we can create Visual Web parts very easily from Visual studio and can deploy it directly from Visual Studio. After deployment, when adding a web part on a sharepoint page you might face the issue that custom web parts are not getting displayed under custom web parts section though your deployment was successful from Visual Studio.

This problem might happen due to activation of features list of your corresponding web parts. To resolved this issue you need to perform the following steps.
1. Go To Site Action from you Share Point Site and Navigate to Site Settings

2. In site setting page select “Site Collection Features” under “Site Collection Administrator” Section.
