datatables

How to: Create DataTables.

如何：创建数据表。

The easiest way to show the contents of these two DataTables is to use two DataGrid controls.

显示这两个 DataTable 的内容的最简单方法是使用两个 DataGrid 控件。

You will now create a master-detail relationship between the two DataTables so a more useful display of the data can be given.

现在可以创建这两个DataTable之间的master - detail(主从复合)关系，以便提供更有用的数据显示。

You will recall that DataTables execute an implicit loop over their rows, and the var attribute indicates the value of the current row during the iteration.

您将再次调用 DataTables 对各表行执行隐式循环，var 属性指示迭代过程中的当前行。

To see the existing field-level validation automatically provided, go to the DataSet Designer, select a field from one of the DataTables and then go to the Properties window.

我们可以在数据集设计器(DataSet Designer)中看到已经存在的字段级验证，从某个DataTable中选择一个字段，然后在属性窗口中就可以找到了。
