以编程方式排序datagridview错误

Question

您好我有datagridview名称data1，并绑定数据到data1从数据库，当我点击列标题排序数据,,一些错误显示..这样的错误“DataGridView控件必须是绑定到IBindingList对象进行排序“。

这是代码的样本..

SomeDataContext db = new SomeDataContext(); 

data1.DataSource = db.data.ToList(); 


private void data1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e) 
{  
     dataGridView1.Sort(dataGridView1.Columns[e.ColumnIndex],     
     ListSortDirection.Ascending);  
} 

任何解决方案家伙？在此先感谢

您需要使用SortableBindingList类：

SortableBindingList<person> persons = new SortableBindingList<person>(); 
persons.Add(new Person(1, "timvw", new DateTime(1980, 04, 30))); 
persons.Add(new Person(2, "John Doe", DateTime.Now)); 

this.dataGridView1.AutoGenerateColumns = false; 
this.ColumnId.DataPropertyName = "Id"; 
this.ColumnName.DataPropertyName = "Name"; 
this.ColumnBirthday.DataPropertyName = "Birthday"; 
this.dataGridView1.DataSource = persons;
