Esc键的datagridview问题 [英] datagridview problem with Esc key

问题描述

嗨
我有一个TextBox和一个DataGridView，它绑定到Windows窗体应用程序中的DataTable.

DataGridView中的某些单元格是强制性的，因此，当用户要离开行时，该程序在RowValidating事件处理程序中检查当前行是否脏，并且强制性单元格没有值，显示一条消息，并取消验证.

当我在datagridview中插入一行时，单击datagridview上的某个位置，返回到新插入的行，更改该行的某些值(例如:空的必填单元格)，然后按Esc键，放弃更改并恢复旧值.但是问题是当我在datagridview中插入一行时，单击TextBox，更改该行的某些值(例如:空的强制性单元格)，然后按Esc键，旧值不会恢复，并且当前行不脏，所以用户无需填写必填单元格即可成功离开该行.
我应该如何解决此问题?

谢谢

Hi
I have a TextBox and a DataGridView which is bound to a DataTable in a windows form application.

Some cells in the DataGridView are mandatory so when the user wants to leave a row, in RowValidating event handler the program checks if the current row is dirty and the mandatory cells do not have value,a message is shown and validation is canceled.

When I insert a row into the datagridview,click somewhere on the datagridview,return to the newly inserted row,change some values of the row(ex:empty mandatory cells) and then press Esc,changes are discarded and the old values are restored.But the problem is when I insert a row into the datagridview,click on the TextBox ,change some values of the row(ex:empty mandatory cells) and then press Esc,old values are not restored,and current row is not dirty,so the user leaves the row successfully without filling in the mandatory cells.
How should I fix this problem?

Thanks
