从DataGrid编辑DataTable [英] Editing a DataTable from a DataGrid

问题描述

我需要帮助 - 再次 -


我有一个DataGrid，其中包含DataTable。当我输入一些测试数据（在代码中）时，它显示得非常好。


现在，我想更改其中一个值Grid，并且具有

DataTable更改。我尝试过使用Validating（和Validated）事件来显示已更改的数据。
它没有改变。我已经尝试将

AcceptChanges和GetChanges添加到我的代码中（对于表格）。


我猜这不应该是难的要做，但我还没弄明白。

谁能告诉我我要离开的东西？

艺术，

现在，我'' d想要更改网格中的一个值，并更改
DataTable。我尝试使用验证（和验证）事件来显示已更改的数据。它没有改变。我已经尝试将
AcceptChanges和GetChanges添加到我的代码中（对于表格）。

这对我来说有点不清楚。您是否正在更改网格中的数据

并希望将其保存在数据表中。或者您是否正在更改

数据表中的数据并且您是否希望它反映在数据网格中？

数据网格中？

我正在更改表单上的数据 - 在网格中 - 如用户在运行程序时会更改它。我希望然后更改DataTable以反映更改。显然我不习惯使用
DataGrids和DataTables。

如果数据表绑定到数据网格，则数据网格自动

更新数据表。

Hi,

I need help -- again --

I have a DataGrid with a DataTable as its source. It displays wonderfully
when I put in some test data (withinin the code).

Now, I''d like to change one of the values in the Grid, and have the
DataTable change. I''ve tried using a Validating (and Validated) event to
display the changed data. It doesn''t change. I''ve tried adding
AcceptChanges and GetChanges to my code (for the Table).

I''m guessing this shouldn''t be hard to do, but I haven''t figured it out.
Can anyone tell me what I''m leaving out?

Thanks,

Art

Art,

Now, I''d like to change one of the values in the Grid, and have the
DataTable change. I''ve tried using a Validating (and Validated) event to
display the changed data. It doesn''t change. I''ve tried adding
AcceptChanges and GetChanges to my code (for the Table).

This is a little bit unclear for me. Are you changing the data in the grid
and want to have it in the datatable. Or are you changing the data in the
datatable and do you want it reflected in the datagrid?

Cor

Cor,

Thanks for taking my question - again.

I am changing the data on the form, in the grid -- as a user would change it
while running the program. I want the DataTable to then be changed to
reflect the change. Clearly I''m new to using DataGrids and DataTables.

Thanks Again,

Art

If the datatable is bound to the datagrid, the datagrid automatically
updates the datatable.
