c# datagridview order rows?
提问by Goober
I have a datagridview with a number of columns, one of these is a datetime column. I want to display the rows from most recent downwards. e.g. Today Yesterday The Day Before Yesterday etc.
我有一个包含多列的数据网格视图，其中之一是日期时间列。我想显示最近向下的行。例如今天昨天昨天前一天等。
Is it possible to do this with the datagridview? The gridviews datasource is an xmldocument.......
是否可以使用 datagridview 来做到这一点？gridviews 数据源是一个xmldocument......
help appreciated greatly.
帮助非常感谢。

this.dataGridView1.Sort(dataGridView1.Columns["DateTime"], ListSortDirection.Ascending);

What is your datasource? You have to have a datasource that supports sorting.
你的数据源是什么？你必须有一个支持排序的数据源。
e.g. a DataTable.
例如一个数据表。
If you have a List you can't sort by default. In theory you need your on class that inherits from BindingList and implements IBindingList (inheritance from BindingList is not nessacary, but makes it a bit easier).
如果您有一个列表，则默认情况下无法进行排序。从理论上讲，您需要从 BindingList 继承并实现 IBindingList 的类（从 BindingList 继承不是必需的，但使它更容易一些）。
If your BingingList is bound to the DataGridView you can sort.
如果您的 BingingList 绑定到 DataGridView，您可以排序。

As far as I know, sorting is not supported for XML data sources. I think your best approach will be to first load the XmlDocument into a dataset and bind that to the grid.
据我所知，XML 数据源不支持排序。我认为您最好的方法是首先将 XmlDocument 加载到数据集并将其绑定到网格。
