The DataViewRowState values are used either to retrieve a particular version of data from a DataRow, or to determine what versions exist.

Set the RowStateFilter property of the DataView to specify which version or versions of data you want to view.

You can use the Boolean operator Or with the values to get more than one version.

The DataTable uses DataViewRowState in the Select method.

In the following example DataTable is created with a single column. The data is changed, and the RowStateFilter of the DataView is set to display different row sets, depending on the DataViewRowState.
