在 gridview/bindingsource 中重新排序记录
我正在使用 Telerik 的 WinForms 控件，并有一个 radGridView，它绑定到绑定源来显示我的数据。我想稍微扩展一下它的功能，为用户提供一种额外的方式来订购记录。
我在网格视图中添加了两个命令按钮（向上、向下）以帮助实现此功能。基本上，当单击“向上”按钮时，我希望当前行与上面的行交换位置；如果单击“向下”按钮，当前行应与下面的行交换位置。
示例数据：
1
2
3
4
5
如果单击第三行的“向上”按钮，数据应如下所示：
1
3
2
4
5
如果单击第三行的“向下”按钮，数据应如下所示：
1
2
4
3
5
我怎样才能实现这一目标？我是否必须修改这些行的绑定源位置或 gridview 行的索引？另一种方式？任何例子都非常感激！
I am using Telerik's WinForms controls and have a radGridView which is bound to a bindingsource to display my data. I would like to expand on the functionality of this a bit to give users an extra way to order the records.
I have added two command buttons to the gridview (Up, Down) to help facilitate this functionality. Basically, when the "Up" button is clicked, I would like the current row to switch places with the row above; if the "Down" button is clicked, the current row should switch places with the row below.
Example data:
1
2
3
4
5
If the "Up" button is clicked on the third row, the data should then look like so:
1
3
2
4
5
If the "Down" button is clicked on the third row, the data should look like this:
1
2
4
3
5
How can I achieve this? Do I have to modifiy the bindingsource positions of these rows, or the gridview row's index? Another way? Any examples are greatly appreciated!

决定使用拖放而不是向上/向下按钮。一切都很好。
Decided to use drag and drop instead of up/down buttons. All is well.
