WPF数据网没有第一次更新
原标题:WPF datagrid not updating first time

我有一个WPF数据网。 电力网的内容受数据集的影响。 电力网正在装上罚款。 一旦电网装满后,我要具体指出,要更新电网内容(以及后端的亚洲开发银行)的电网中的一项活动。 这样做是行之有效的,但第一项变化并没有实现。 如果我第二次回来并改变同样的数据项目,我看到对亚洲开发银行的改动。

我一栏的XAML出现在一个称为dgproducts的数据网中。 页: 1

<my:DataGridTextColumn Header="Name" Width="Auto" Binding="{Binding ProductName, NotifyOnSourceUpdated=True, UpdateSourceTrigger=LostFocus, Mode=TwoWay}" />

最新信息是:

prodAdapter.Update(dgProducts.DataContext.Data)

更新方法源自表格中确定的数据集,该数据集将可促进的产品作为参数。 这似乎在发挥作用,只是一项交易。 如果我认为数据可按节制计算,我看一看我对一栏所作的价值改动,那就不是承诺的。

我没有某处的复习,或者还有什么东西被忽视?

最佳回答

资料来源似乎是在实际进行电网变化之前发射的。 我使用了“小组”活动,这些活动是适当的。
