以編程方式排序datagridview錯誤

Question

您好我有datagridview名稱data1，並綁定數據到data1從數據庫，當我點擊列標題排序數據,,一些錯誤顯示..這樣的錯誤「DataGridView控件必須是綁定到IBindingList對象進行排序「。

這是代碼的樣本..

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);  
} 

任何解決方案傢伙？在此先感謝

您需要使用SortableBindingList類：

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;
