WPF Newbie Grid绑定问题

我是WPF的新手。我一直在将绑定数据发送到网格。然而，下面的例子从未调用将用于填充网格的方法。我需要做什么才能做到这一点？WPF Newbie Grid绑定问题

您需要将datagrid绑定到数据源..在这种情况下，其中一个ObjectDataProviders。

因此，上述改变

ItemsSource="{Binding Path=Table}"

要

ItemsSource="{StaticResource CurrencyConversionList}"

在给定的代码，在DataContext为您的DataGrid（甚至窗口）从未设置过的任何地方，所以你“的ItemsSource =” DataGrid的{绑定路径=表}“'将不起作用。也许你需要在你的构造函数中做一些类似“this.DataContext = qualityDataSet”的东西。
