C＃DataGridView使用Generic List作为基础源进行排序 [英] C# DataGridView sorting with Generic List as underlying source

问题描述

我正在使用 Windows Forms DataGridView 来显示 MyObject 对象的通用列表。

I'm using a Windows Forms DataGridView to display a generic list of MyObject objects.

首先我将这个集合包装到一个 BindingSource 集合中，然后：

First of all I wrap this collection into a BindingSource Collection, then:

dataGridView.DataSource = myBindingSource;

我想做的是允许用户通过点击列的标题对列进行排序代表MyObject中的具体属性。

What I want to do is allow the user to sort the columns by clickin on the header of the column representing a concrete Property in MyObject.

我已经阅读了一些文章，我应该在绑定之前进行排序。但是，如果我想要实时排序列表，那么这并不能帮助我。

I've read some articles that I should do sorting before binding. But it does not help me if I want to sort the columns in real time, being said when it's already binded.

问题是，我需要做什么，所以我可以看到DataGridView中的排序箭头，我可以对每列进行排序？

The question is, what exactly do I need to do, so I could see the sorting arrows in DataGridView and I could sort every column ?

推荐答案

我的解决方案是这样的：

My Solution is this:

我自己使用myBindingSource，我在单独的线程中排序，分组..
然后我只需将结果绑定到DataGridView 。

I work with myBindingSource at my own, I do sorting, grouping ..whatever in a separate thread. Then I simply bind the result to the DataGridView.

myDataGridView.DataSource = bindingSource;

为此，我已经将所有要排序的列设置为 '（在设计师中）
然后我手动添加箭头（ASCENDING / DESCENDING）
通过设置

For this purpose I've setted all the columns to be sorted 'Programatically' (in designer) Then I manually add the arrow (ASCENDING / DESCENDING) by setting

cell.SortGlyphDirection = ... ; 

在代码背后。
