How to get multiple selected records of TcxGridDBTableView and delete all of them? (MultiSelect = True)

nusntu

I have set TcxGridDBTableView.OptionSelection.MultiSelect = True,
How do I know which records have been selected?

// Show the value of the 3rd field of all selected records
  for i: = 0 to cxGrid1DBTableView1.Controller.SelectedRecordCount-1 do
    ShowMessage (cxGrid1DBTableView1.Controller.SelectedRecords [i] .Values ​​[2]);

To add, it ’s better to delete backwards when deleting
for i: = cxGrid1DBTableView1.Controller.SelectedRecordCount-1 downto 0 do
  //delete

zy_1306

for i: = cxGrid1DBTableView1.Controller.SelectedRecordCount-1 downto 0 do
  //cxGrid1DBTableView1.Controller.SelectedRecords[i] ......

zy_1306

var
  i, n: Integer;
begin
  n: = cxGrid1DBTableView1.IndexOfItem (cxGrid1DBTableView1.FindItemByName ('Id'));
  for i: = cxGrid1DBTableView1.Controller.SelectedRecordCount-1 downto 0 do
    ShowMessage (cxGrid1DBTableView1.Controller.SelectedRecords [i] .Values ​​[n]);
end;
