问题描述

如何在DataGrid中查看用户是否更改了数据，以便我可以询问

他保存更改或不是吗？


谢谢，


彼得

Hi,

How can I see if the Data is changed by the user in my DataGrid so I can ask
him to save the changes or not?

Thanks,

Pieter

推荐答案

Pieter，


您可以检查底层数据表是否有变化。


Unluckely没有方法datatable.haschanges。


所以你应该使用伪造的解决方法


myNewTable作为新的datatable = datasource.table.getchanges

而不是测试是否那些充满了行。


我希望这能给出一个想法吗？

Pieter,

You can check if the underlaying datatable has changes.

Unluckely there is no method datatable.haschanges.

So you should use a workaround something as pseudo

myNewTable as new datatable = datasource.table.getchanges
And than test if that is filled with rows.

I hope that this gives an idea?

Cor

嗯，谢谢，这似乎有用。

但是如果我的DataGrid中有2个绑定的DataTables，我不会只做支票
目前在DataView中的记录？

Hm thanks, that seems to work.
But what if I have 2 bound DataTables in my DataGrid, and I wan''t only do
the check on the records that are currently in the DataView?

数据视图还有一个表属性告诉哪个表格

Pieter,

The dataview has as well a table property which tells which table it
references

嗯谢谢，这似乎有效。
