Dim instance As DataRowState

Member nameDescription
Supported by the .NET Compact FrameworkSupported by the XNA FrameworkDetachedThe row has been created but is not part of any DataRowCollection. A DataRow is in this state immediately after it has been created and before it is added to a collection, or if it has been removed from a collection.
Supported by the .NET Compact FrameworkSupported by the XNA FrameworkUnchangedThe row has not changed since AcceptChanges was last called.
Supported by the .NET Compact FrameworkSupported by the XNA FrameworkAddedThe row has been added to a DataRowCollection, and AcceptChanges has not been called.
Supported by the .NET Compact FrameworkSupported by the XNA FrameworkDeletedThe row was deleted using the Delete method of the DataRow.
Supported by the .NET Compact FrameworkSupported by the XNA FrameworkModifiedThe row has been modified and AcceptChanges has not been called.

The DataRowState enumeration is returned by the RowState property of the DataRow class.

The following example first creates a new DataTable with one column, then creates a single DataRow. As the DataRow is created, added, modified, and deleted, its RowState is printed.

Private Sub DemonstrateRowState()
    'Run a function to create a DataTable with one column. 
    Dim dataTable As DataTable = MakeTable()
    Dim dataRow As DataRow

    ' Create a new DataRow.
    dataRow = dataTable.NewRow()
    ' Detached row.
    Console.WriteLine(String.Format("New Row {0}", dataRow.RowState))

    dataTable.Rows.Add(dataRow)
    ' New row.
    Console.WriteLine(String.Format("AddRow {0}", dataRow.RowState))

    dataTable.AcceptChanges()
    ' Unchanged row.
    Console.WriteLine(String.Format("AcceptChanges {0}", dataRow.RowState))

    dataRow("FirstName") = "Scott" 
    ' Modified row.
    Console.WriteLine(String.Format("Modified {0}", dataRow.RowState))

    dataRow.Delete()
    ' Deleted row.
    Console.WriteLine(String.Format("Deleted {0}", dataRow.RowState))
End Sub 

Private Function MakeTable() As DataTable
    ' Make a simple table with one column. 
    Dim dt As New DataTable("dataTable")
    Dim firstName As New DataColumn("FirstName", _
       Type.GetType("System.String"))
    dt.Columns.Add(firstName)
    Return dt
End Function
