DataRow.RowState Property

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)

public DataRowState RowState { get; }
/** @property */
public DataRowState get_RowState ()

public function get RowState () : DataRowState

Not applicable.

Property Value

One of the DataRowState values.

The value of the RowState depends on two factors: the kind of operation has been performed on the row, and 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;
}
