In This Topic
    MaxRecords Property
    In This Topic
    Gets or sets max number of records to fetch starting from StartRecord.
    Syntax
    'Declaration
     
    Public Property MaxRecords As Integer
    public int MaxRecords {get; set;}

    Property Value

    Max number of records to fetch starting from StartRecord.
    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 Test.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 Test.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
