为什么我的列排序在winforms .NET数据网格? [英] Why wont my column sort in a winforms .NET datagrid?
问题描述
List< cLineItem>
。 cLineItem是非常简单的类,其属性如单位(int),描述(字符串)和单位金额(float)。 在代码中,我填充行列表,然后设置数据源:
dataGridView1.DataSource = lines;
但是,即使网格中的每一列都设置为可排序, ,当您单击列标题时,它不排序行。
在DataGridView中排序默认情况下不起作用,除非您的源显式支持排序。您需要将数据源包装在 SortableBindingList 中。您可以使用此 zip文件中的PropertyComparer.cs和SortableBindingList.cs文件并使用它:
dataGridView1.DataSource = new SortableBindingList< cLineItem>(lines);
I have a WinForms .NET datagrid whose data source is a List<cLineItem>
called lines. cLineItem is very simple class with properties like units (int), description (string) and unit amount (float).
In code, i populate the list of lines and then set the data source:
dataGridView1.DataSource = lines;
This correctly populates the grid, however, even though each of the columns in the grid are set to Sortable, when you click a column header, it doesnt sort the rows.
Sorting in DataGridView doesn't work by default, unless your source explicitly supports sorting. You need to wrap your data source in a SortableBindingList. You can use the files PropertyComparer.cs and SortableBindingList.cs from this zip file and use it like this:
dataGridView1.DataSource = new SortableBindingList<cLineItem>(lines);
