SqlCeDataAdapter.RowUpdating Event

Occurs during a call to Update before an update command is executed against the data source. The attempt to update is made, and then this event fires.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

public event SqlCeRowUpdatingEventHandler RowUpdating
/** @event */
public void add_RowUpdating (SqlCeRowUpdatingEventHandler value)

/** @event */
public void remove_RowUpdating (SqlCeRowUpdatingEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

When using Update, there are two events that occur for each data row updated. The order of execution is as follows:

  1. The values in the DataRow are moved to the parameter values.

  2. The OnRowUpdating event is raised.

  3. The command executes.

  4. If the command is set to FirstReturnedRecord, then the first returned result is placed in the DataRow.

  5. The OnRowUpdated event is raised.

  6. AcceptChanges is called.

The following example shows the RowUpdating and RowUpdated events in use.

public void Snippet5()
{
    // Create DataAdapter
    //
    SqlCeDataAdapter adp = new SqlCeDataAdapter(
        "SELECT * FROM products",
        "Data Source = MyDatabase.sdf");

    SqlCeCommandBuilder cb = new SqlCeCommandBuilder(adp);

    // Create and fill the dataset (select only first 5 rows)
    //
    DataSet ds = new DataSet();
    adp.Fill(ds, 0, 5, "Table");

    // Modify dataSet
    //
    DataTable table = ds.Tables["Table"];
    table.Rows[1]["Product Name"] = "Asian Chai";

    // Add handlers
    //
    adp.RowUpdating += new SqlCeRowUpdatingEventHandler(OnRowUpdating);
    adp.RowUpdated += new SqlCeRowUpdatedEventHandler(OnRowUpdated);

    // Update, this operation fires two events (RowUpdating/RowUpdated)  
    //
    adp.Update(ds, "Table");

    // Remove handlers
    //
    adp.RowUpdating -= new SqlCeRowUpdatingEventHandler(OnRowUpdating);
    adp.RowUpdated -= new SqlCeRowUpdatedEventHandler(OnRowUpdated);


private static void OnRowUpdating(object sender, SqlCeRowUpdatingEventArgs e)
{
    Console.WriteLine("OnRowUpdating");
    Console.WriteLine(e.Command.CommandText);
    Console.WriteLine(e.StatementType);
    Console.WriteLine(e.Status);


private static void OnRowUpdated(object sender, SqlCeRowUpdatedEventArgs e)
{
    Console.WriteLine("OnRowUpdated");
    Console.WriteLine(e.Command.CommandText);
    Console.WriteLine(e.StatementType);
    Console.WriteLine(e.Status);
