我尝试过：

How to bind sub items in List item in win forms with maximize and minimize buttons c#, i have just bind listitem with multiple columns,here is my code

What I have tried:

listView2.Columns.Add("Name", 241, HorizontalAlignment.Left);
listView2.Columns.Add("Mobile Number", 245, HorizontalAlignment.Left);
listView2.Columns.Add("ASET", 245, HorizontalAlignment.Left);
// Getting the data to a datasource
SqlConnection con = new SqlConnection("Data Source=192.168.1.101\\SQLEXPRESS;Initial Catalog=algen_db;User ID=vipl-user;Password=vipl-user!@#$%");
listView2.Items.Clear();
SqlDataAdapter adp = new SqlDataAdapter("select acdesc,acno,speactype,acremarks from chartaccount where ParentAcNo is null order by AcNo", con);
DataTable dt = new DataTable();
adp.Fill(dt);

string[] Str = new string[4];
ListViewItem newItm;
foreach (DataRow dataRow in dt.Rows)
{
    Str[0] = dataRow["acdesc"].ToString();
    Str[1] = dataRow["acno"].ToString();
    Str[2] = dataRow["speactype"].ToString();
    Str[3] = dataRow["acremarks"].ToString();
    newItm = new ListViewItem(Str);
    listView2.Items.Add(newItm);              
    newItm.SubItems.Add("Aaa");
}

SqlDataAdapter adp = new SqlDataAdapter（ select acdesc来自chartaccount的acno，speactype，acremarks，其中ParentAcNo是由AcNo，con）的空订单;
DataTable dt = new DataTable（）;
adp.Fill（dt）;

string [] Str = new string [ 4 ];
ListViewItem newItm;
foreach （DataRow dataRow in dt.Rows）
{
Str [ 0 ] = dataRow [ acdesc]。ToString（） ;
Str [ 1 ] = dataRow [ acno]。ToString（）;

%"); listView2.Items.Clear(); SqlDataAdapter adp = new SqlDataAdapter("select acdesc,acno,speactype,acremarks from chartaccount where ParentAcNo is null order by AcNo", con); DataTable dt = new DataTable(); adp.Fill(dt); string[] Str = new string[4]; ListViewItem newItm; foreach (DataRow dataRow in dt.Rows) { Str[0] = dataRow["acdesc"].ToString(); Str[1] = dataRow["acno"].ToString(); Str[2] = dataRow["speactype"].ToString(); Str[3] = dataRow["acremarks"].ToString(); newItm = new ListViewItem(Str); listView2.Items.Add(newItm); newItm.SubItems.Add("Aaa"); }
