如何對DataGridView進行排序編輯winform中的coulmn值使用c＃

Question

我想排序datagridview。當用戶從這個事件CellValueChanged對DataGrid進行了一些更改時。在CellValueChanged完成之後的 datagridview應根據該列進行排序。我有綁定datagrid列表。

您可以使用從DataGridViewCellEventArgsColumnIndex財產sort

public Form1() 
    { 
     InitializeComponent(); 

     dataGridView1.CellValueChanged +=new DataGridViewCellEventHandler(dataGridView1_CellValueChanged); 

     DataTable dt = new DataTable(); 
     dt.Columns.Add(new DataColumn("col1")); 
     dt.Columns.Add(new DataColumn("col2")); 
     dt.Columns.Add(new DataColumn("col3")); 

     var r1 = dt.NewRow(); 
     r1["col1"] = "a1"; 
     r1["col2"] = "b1"; 
     r1["col3"] = "c1"; 

     var r2 = dt.NewRow(); 
     r2["col1"] = "a2"; 
     r2["col2"] = "b2"; 
     r2["col3"] = "c2"; 

     var r3 = dt.NewRow(); 
     r3["col1"] = "a3"; 
     r3["col2"] = "b3"; 
     r3["col3"] = "c3"; 

     dt.Rows.Add(r1); 
     dt.Rows.Add(r2); 
     dt.Rows.Add(r3); 

     BindingSource bs = new BindingSource(); 
     bs.DataSource = dt; 

     dataGridView1.DataSource = bs; 

    } 

    private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) 
    { 
     var dataGrid = (DataGridView)sender; 
     var dataGridColumn = dataGrid.Columns[e.ColumnIndex]; 
     dataGrid.Sort(dataGridColumn, ListSortDirection.Ascending); 
    }
