按列内容对Datagrid进行排序 [英] Sort Datagrid by Column contents

问题描述

我想根据列内容在网格中订购数据。



我已经尝试了指令（ OperationGrid 是我的grid的名称，以及 Part Number 第一列的标题）

I want to order the data in a grid based on a column contents.

I have tryed the instruction (OperationGrid is my grid''s name, and "Part Number" the title of the first column)

OperationGrid.Sort(OperationGrid.Columns["Part Number"], ListSortDirection.Ascending);

在这种情况下，我收到错误

价值不能为空。

参数名称：dataGridViewColumn



不知道错误来自哪里？



和

In that case, I get the error
"Value cannot be null.
Parameter name: dataGridViewColumn"

Any idea of where can the error come from?

and also

OperationGrid.Sort(OperationGrid.Columns[0], ListSortDirection.Ascending);

现在我收到错误 DataGridView控件必须绑定到要排序的IBindingList对象。



知道错误来自哪里？

也许我忘了要定义的东西？但网格工作正常而没有排序。





我相信问题在于我忘记了要声明的内容或类型可以是错误。有什么想法吗？





提前谢谢。

David

Now I get the error "DataGridView control must be bound to an IBindingList object to be sorted".

Any idea of where can the error come from?
Maybe I forgot something to define? but the grid works fine without sorting.


I believe that the problem is that I have forgotten something to declare or a type can be wrong. Any idea about that?


Thank you in advance.
David

推荐答案

试试这个链接：



以编程方式排序DataGrid [ ^ ]

try this link:

Sorting DataGrid programmatically[^]

定义IComparable功能并在课程中创建比较功能：

Define the IComparable feature and create the comparison feature inside the class:

public class Component : IComparable<component>
{
   private string PartNumber;

...

   public int CompareTo(Component toSort)
   {
      return PartNumber.CompareTo(toSort.PartNumber)
   }

...

}
</component>

用法：

Usage:

private void ListSort(list<component> _list2Sort)
{
   _list2Sort.Sort();
}

</component>
