c# - Copying A SINGLE SELECTED row from a datagridview to another datagridview -

what need : 1. when user clicks on row of datagriview. row displayed in datagridview (so can edited etc...)

note : grid_display = need row. note : grid_detail = need single row copied.

what have till now:

   foreach (datagridviewcolumn c in grid_display.columns)             {                 grid_detail.columns.add(c.clone() datagridviewcolumn);             }              //then can copy rows values 1 one (working on selectedrows collection)             foreach (datagridviewrow r in grid_display.selectedrows)             {                 int index = grid_detail.rows.add(r.clone() datagridviewrow);                 foreach (datagridviewcell o in r.cells)                 {                     grid_detail.rows[index].cells[o.columnindex].value = o.value;                 }             }              } 

i able make new row. not feed in selected row in it. ?

as mentioned in comment already, should use datasource datagridviews , use datagridview view only.

here have complete example demonstrates how use datatable datasource datagridview , move datarow between them.

1. creata new windows forms project , copy paste code.
2. click on row, clicking left row (indicated small arrow > ) in datagridview
3. click on button below datagridview move selected datarow other datagridview

note 1: controls crated in form1_load dont bother drag dropping controls on form.

note 2: if have column selected, no rows moved. have select entire row.

with should able implement logic of when move row grid_detail , when move grid_display.
