DataRow.RowState Property
.NET Framework 2.0
Gets the current state of the row with regard to its relationship to the DataRowCollection.
Namespace: System.Data
Assembly: System.Data (in system.data.dll)
Assembly: System.Data (in system.data.dll)
The value of the RowState depends on two factors: (1) the kind of operation has been performed on the row, and (2) whether AcceptChanges has been called on the DataRow.
The following example first creates a new DataTable with one column, and then creates a single DataRow. As the DataRow is created, added, modified, and deleted, its RowState is printed.
private void DemonstrateRowState() { // Run a function to create a DataTable with one column. DataTable table = MakeTable(); DataRow row; // Create a new DataRow. row = table.NewRow(); // Detached row. Console.WriteLine("New Row " + row.RowState); table.Rows.Add(row); // New row. Console.WriteLine("AddRow " + row.RowState); table.AcceptChanges(); // Unchanged row. Console.WriteLine("AcceptChanges " + row.RowState); row["FirstName"] = "Scott"; // Modified row. Console.WriteLine("Modified " + row.RowState); row.Delete(); // Deleted row. Console.WriteLine("Deleted " + row.RowState); private DataTable MakeTable() { // Make a simple table with one column. DataTable table = new DataTable("table"); DataColumn dcFirstName = new DataColumn( "FirstName", Type.GetType("System.String")); table.Columns.Add(dcFirstName); return table;
