TAILIEUCHUNG - Using the Default Sort Algorithm

Using the Default Sort Algorithm If you want to sort the DataRowView objects in your DataView based on the primary key of your DataTable, you can use a shortcut. Instead of setting the Sort property of your DataView | Using the Default Sort Algorithm If you want to sort the DataRowView objects in your DataView based on the primary key of your DataTable you can use a shortcut. Instead of setting the Sort property of your DataView you set the PrimaryKey property of your DataTable and then set the ApplyDefaultSort property of your DataView to true. The Sort property of your DataView is then automatically set to the primary key of your DataTable. This causes the DataRowView objects in your DataView to be sorted in ascending order based on the primary key column values. Let s take a look at an example. The following code sets the PrimaryKey property of the customersDT DataTable to the CustomerlD DataColumn new DataColumn CustomerID The next example sets the ApplyDefaultSort property of customersDV to true true The Sort property of customersDV is then set to CustomerlD which causes the DataRowView objects to be sorted by the ascending CustomerID values. Note You ll find the code examples in this section in the program. The listing is omitted from this book for .
