DataSet Quick watch
I know a lot of people use the DataSet QuickWatch utiltity developed by Mohammed Barqawi. The first version of this was posted May 2004.
Matt Simner implemented a few additional features which are very interesting, such as:
- Typed DataSet support.
- Support for DataTable and DataRow
- Row Filter option
- Visual changes.
Those interested can find the full article here. From here, you can also download the code.
