Devexpress - 如何将GridControl的数据放在另一个GridControl的排序/过滤的数据上？

问题描述

我的表单上有两个GridControl。一个是相当大的数据集，包括一个名为Score的列。我想让我的另一个GridControl显示一个这样的子集（例如，基于Score的前3和底3）。

我如何最好地完成这项工作？如果它是相同的GridControl，我想我可以使用不同的视图，但由于它是完全分开的，我应该抓住一个视图的副本，过滤/排序数据并将其显示为一个新的数据集？或者有没有办法将我的第二个GridControl的数据链接到我的第一个？

编辑：我可以做 grid2。 datasource = grid1.datasource 并从那里走。表不会有任何动态更新，所以也许这是要走的路？

解决方案

我将使用以下方法：

1）创建一个新的DataView，根据您的方法进行过滤，并将第二个gridControl的DataSource设置为此DataView;

OR

2）将第二个GridControl的DataSource属性设置为相同的值，并过滤相应的GridView。

I have two GridControls on my form. One is a fairly large dataset, including a column named Score. I want my other GridControl to show a subset of this (e.g. Top 3 and Bottom 3 based on the values of Score).

How can I best accomplish this? If it were the same GridControl I imagine I could just use a different view, but since it's completely separate, should I just grab a copy of the view, filter/sort the data and display it as a new dataset? Or is there a way to link my second GridControl's data to my first's?

edit: I could do grid2.datasource = grid1.datasource and go from there. There won't be any dynamic updates to the table so maybe this is the way to go?

解决方案

I would use the following approach:

1) create a new DataView, filter it based on your approach and set the second gridControl's DataSource to this DataView;

OR

2) set the DataSource property of the second GridControl to the same value and filter the corresponding GridView.
