Thread Selecting lines in the grid

What are the ways that I can select lines in the grid, so that I can then operate on the rows selected (to delete, or to update)?

Ideally I need a checkbox that is single select.

Is this available in any form today?

Is there anything in v3 that will change it, and in any short timescale?

Thanks,

You can do it in a couple of different ways.


Setting TGrid's  RowSelect option will make it only select whole rows at a time.
And then you cen call the functions to delete or update or whatever.

Another thing you can do is add a checkbox field to the grid and dataset, and then have a button which Deletes Selected by doing something like:

  dataset1.Last;
  while not DataSet1.BOF do begin
      if dataset1.columns.column['mycheckbox'].AsBoolean then dataset1.Delete;
     dataset1.Prior;
 end;
