WPF DataGrid CellEditEnding - DataSet不更新直到行丢失焦点 [英] WPF DataGrid CellEditEnding - DataSet Not Updating Till Row Lost Focus

问题描述

一旦细胞从编辑中失去焦点，我需要能够更新数据集的值。我知道当细胞失去焦点时（CellEditEnding），但问题是，实际更新它的上下文项目不会发生，直到焦点对该行实际发生。当只剩下一个项目时，这是一个巨大的问题，因为它可能永远不会失去焦点。

如何确保每次列编辑完成（CellEditEnding）时，该行的实际上下文会在那一点更新（不只是当行丢失时焦点）

提前感谢

这是一篇博客文章，描述了这项技术：

I need to be able to update values of a dataset once a cell loses focus from editing. I know when the cell loses focus (CellEditEnding), but problem is, the actual updating of it's context item does not occur till focus on that row actually occurs. This becomes a huge issue when there is only one item left, since it may never lose focus.

How do I make sure that each time a column edit is complete (CellEditEnding), the actual context for that row is updated at that point (not just when the row loses focus)

Thanks in advance!

解决方案

You can use DataGrid.CommitEdit from your DataGrid.CellEditEnding handler, being sure to handle reentrancy.
