Question

我想使用combobox对列表框进行排序，组合框将包括A-Z和Z-A，那么我该怎么做才能让它工作？

我的一些列表框代码，lst_OrderName是我想要排序的代码。

private void AllorderBySearch()
        {



            using (connection = new SqlConnection(connectionString))
            using (SqlDataAdapter adapter = new SqlDataAdapter("select* from  Tbl_order WHERE CustomerNo = '" + txt_CustomerNo.Text + "' And OrderName LIKE '%" + txt_OrderNo.Text + "%' AND OrderName LIKE '%" + txt_OrderNo.Text + "%' AND OrderName LIKE '%" + txt_OrderNo.Text + "%' AND Date between '" + dateTimePicker1.Text + " 00:00:00.000' AND '" + dateTimePicker1.Text + " 23:59:59.999'; ", connection))
            {


                DataTable Tbl_order = new DataTable();
                connection.Open(); //opens the connection
                adapter.Fill(Tbl_order);
                connection.Close(); //Closes the connection

                lst_CustomerNo.DataSource = Tbl_order; //assigns a datasource
                lst_CustomerNo.DisplayMember = "CustomerNo"; //assigns display
                lst_CustomerNo.ValueMember = "CustomerNo";

                lst_OrderName.DataSource = Tbl_order;
                lst_OrderName.DisplayMember = "OrderName";
                lst_OrderName.ValueMember = "OrderName";

                lst_Quantity.DataSource = Tbl_order;
                lst_Quantity.DisplayMember = "Quantity";
                lst_Quantity.ValueMember = "Quantity";

                lst_Price.DataSource = Tbl_order;
                lst_Price.DisplayMember = "Price";
                lst_Price.ValueMember = "Price";

                lst_datetime.DataSource = Tbl_order;
                lst_datetime.DisplayMember = "Date";
                lst_datetime.ValueMember = "Date";

            }
        }

我创建了组合框，但我没有做任何事情，但是我不知道如何按照我想要的方式制作它。你能帮帮我吗？

Answer 1

您必须使用临时对象进行排序，如冒泡排序

Answer 2

当您使用DataTable作为数据源时，以下内容应该有效：

{{1}}

将上述事件附加到您的组合框SelectedIndexChanged操作..
