c# - Winform clone DataGridViewRow along with DataBoundItem -

i have list of pocos this:

list<a> alist; public class {     public string m { get; set; }     public string n { get; set; }     public bs list<b> { get; set; } } public class b {      public string x { get; set; }     public string y { get; set; } } 

i can bind datagridview dgv no problem. want clone row, along copy of a in row.

var row = dgv.selectedcells[0].owningrow; var alist= (list<a>)((bindingsource)dgv.datasource).datasource; var = (a)row.databounditem;  var clone = (datagridviewrow)row.clone(); //only copied blank row, no content dgv.rows.add(clone); var copya = (a)clone.databounditem;  as.add(copya); // 'copya' null, because databouditem not copied. 

how make happen clone row has clone data?

i prefer simpe work around, not going notifypropertychanged, bindinglist , if possible?

add new "row" in data instead binded datagridview.

var currentcell = dgv.currentcell; var bs = (bindingsource)dgv.datasource; var data = (list<a>)bs.datasource; var currentselection = (a)row.databounditem; data.add(currentselection);  bs.resetbindings(false); // should refresh grid dgv.currentcell = currentcell; // put current cell
