In This Topic
    StartRecord Property
    In This Topic
    Gets or sets record number to start.
    Syntax
    'Declaration
     
    Public Property StartRecord As Integer
    public int StartRecord {get; set;}

    Property Value

    Record number to start. Value 0 means the first row, 1 means the second, and so on.
    Remarks

    StartRecord and MaxRecords take effect only when DbDataTable is opened using the Active property or the Open method.

    Another way to access only a subset of rows is to use FillPage method.

    Assigning a value to this property invokes the fill operation.

    Example
    This sample shows how to access only a part of dataset returned by a query.
    static void FillDataTable(DbDataTable myDataTable, IDbConnection myConnection)
    {
      myDataTable.Connection = myConnection;
      myDataTable.SelectCommand = myConnection.CreateCommand();
      myDataTable.SelectCommand.CommandText = "SELECT EmpNo, EName FROM Emp";
      myDataTable.StartRecord = 0;
      myDataTable.MaxRecords = 10;
      try
      {
        myDataTable.Active = true;
        foreach(DataRow myRow in myDataTable.Rows)
        {
          foreach(DataColumn myCol in myDataTable.Columns)
          {
            Console.Write(myRow[myCol]+"\t");
          }
          Console.WriteLine();
        }
      }
      finally
      {
        myDataTable.Clear();
      }
    }
    Public Sub FillDataTable(ByVal myDataTable As DbDataTable, ByVal myConnection As IDbConnection)
      Try
        myDataTable.Connection = myConnection
        myDataTable.SelectCommand = myConnection.CreateCommand()
        myDataTable.SelectCommand.CommandText = "SELECT EmpNo, EName FROM Emp"
        myDataTable.StartRecord = 0
        myDataTable.MaxRecords = 10
        myDataTable.Active = True
        Dim myRow As DataRow
        Dim myCol As DataColumn
        For Each myRow In myDataTable.Rows
          For Each myCol In myDataTable.Columns
            Console.Write(myRow(myCol) & Chr(9))
          Next myCol
          Console.WriteLine()
        Next myRow
      Finally
        myDataTable.Clear()
      End Try
    End Sub
