Deleting Data using Business Objects

There are several overloads of the Delete() method that allow you to delete records in a business object's DataSet.

• Deletes the specified DataRow

  protected internal virtual bool DeleteRow(DataRow dr)
  

• Deletes the nth record in the specified DataSet's specified DataTable

  public virtual bool Delete(DataSet ds, string tableName, int row)
  

• Deletes the nth record in the specified DataSet's default DataTable

  public virtual bool Delete(DataSet ds, int row)
  

• Deletes the first record in the current DataSet's specified DataTable

  public virtual bool Delete(string tableName)
  

• Deletes the first record in the current DataSet's default DataTable

  public override bool Delete()
  

• Deletes the record with the specified primary key value in the specified table

  public virtual bool Delete(object primaryKeyValue, string tableName)
  

• Deletes the specified row in the current DataSet

  public virtual bool Delete(DataRowView drView)
  

• Deletes the record with the specified primary key values in the specified table

  public virtual bool Delete(object[] primaryKeyValues, string tableName)
  

  Example in C#:

  object[] KeyValues = new object[] { 1001, 16 };
  orderDetail.Delete(KeyValues, "OrderDetail");

  In VB .NET:

  Dim KeyValues() As Object = {1001, 16}
  orderDetail.Delete(KeyValues, "OrderDetail")

• Deletes the record with the specified primary key value in the default table

  public virtual bool Delete(object primaryKeyValue)
  

• Deletes the record with the specified primary key values in the default table
