Use the adapter's Update method to update the data. This overloaded method can take a DataTable as a parameter and will commit all the changes made to the data source. The name of the data table can be passed as an argument and can also be used to update the entire dataset in a more traditional manner. When using a data table as an argument to the Update method, the adapter evaluates the changes that have been made to the data table and executes the appropriate command for each row (INSERT, UPDATE, or DELETE).

The example below updates the GoalHeadingId of one of the GoalHeadings entries.

C#

using (Dynamics365Connection connection = new Dynamics365Connection(connectionString)) {
  Dynamics365DataAdapter dataAdapter = new Dynamics365DataAdapter(
    "SELECT GoalHeadingId, GoalHeadingId FROM GoalHeadings", connection);

  dataAdapter.UpdateCommand = new Dynamics365Command(
    "UPDATE GoalHeadings SET GoalHeadingId = @GoalHeadingId " +
    "WHERE GoalHeadingId = @GoalHeadingId", connection);
 
  dataAdapter.UpdateCommand.Parameters.Add(new Dynamics365Parameter("@GoalHeadingId", DbType.String, "GoalHeadingId"));
  dataAdapter.UpdateCommand.Parameters.Add(new Dynamics365Parameter("@GoalHeadingId", DbType.String, "GoalHeadingId"));
  dataAdapter.UpdateCommand.Parameters[1].SourceVersion = DataRowVersion.Original;

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  DataRow firstrow = table.Rows[0];
  firstrow["GoalHeadingId"] = "Jon Doe";

  dataAdapter.Update(table);

  Console.WriteLine("Rows after update.");
  
  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["GoalHeadingId"], row["GoalHeadingId"]);
  }
}

VB.NET

Using connection As New Dynamics365Connection(connectionString)
  Dim dataAdapter As New Dynamics365DataAdapter(
    "SELECT GoalHeadingId, GoalHeadingId FROM GoalHeadings", connection)
  
  dataAdapter.UpdateCommand = New Dynamics365Command(
    "UPDATE GoalHeadings SET GoalHeadingId = @GoalHeadingId " +
    "WHERE GoalHeadingId = @GoalHeadingId", connection)
  
  dataAdapter.UpdateCommand.Parameters.Add(new Dynamics365Parameter("@GoalHeadingId", DbType.String, "GoalHeadingId"))
  dataAdapter.UpdateCommand.Parameters.Add(new Dynamics365Parameter("@GoalHeadingId", DbType.String, "GoalHeadingId"))
  dataAdapter.UpdateCommand.Parameters(1).SourceVersion = DataRowVersion.Original
  
  Dim table As New DataTable()
  dataAdapter.Fill(table)
  
  Dim firstrow As DataRow = table.Rows(0)
  firstrow("GoalHeadingId") = "Jon Doe"
  
  dataAdapter.Update(table)
  
  Console.WriteLine("Rows after update.")
  
  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("GoalHeadingId"), row("GoalHeadingId"))
  Next
