Windows在选择最后一行时形成DataGridView绑定保存 [英] Windows forms DataGridView binding save when last row is selected

问题描述

您好，

将DataGridView与数据源和defaultvalues一起使用时，我遇到了一些问题。

I'm having some problems when using DataGridView with a datasource and defaultvaluesneeded.

我有一个网格限制到BindingList，当我尝试保存时，如果选择了最后一行，那么我在最后一行的BindingList中有一个额外的条目。它只有defaultvaluesneeded的值。 

I have a grid bounded to a BindingList and when i try to Save, if the last row is selected, than i have an extra entry in the BindingList for that last row. It has only the values from defaultvaluesneeded. 

有没有办法阻止它？

提前致谢，

Sergiu

最好的问候。

推荐答案

看起来你需要首先检查最后一行是否在发出save方法之前有任何默认值，因为DataGridView没有这个作为检查，它在你的控制之下。您可以通过查询基础数据
来检查行，而不是主键值与切线相关，确定是否有任何或所有字段都有默认值。

Seems like you would need to first check to see if the last row has any default values prior to issuing the save method as a DataGridView does not have this as a check, it's under your control. You could check for the row by querying the underlying data for a row without a primary key value in tangent with determining if any or all fields have default values.
