UniDBgrid with check boxes (limit number of rows that can be selected)

[SergioFeitoza]

I have a TuniDBgrid working with 10 lines working well with check boxes. So I can select from one line to 10 lines

What should I do if I want to limit the number of selected lines to 4.

That is , when I select 4 tha "not selected ones" become unable to select.  ?

Hello,

You can try to use this code:

function beforeselect(sender, record, index, eOpts)
{
    return !(sender.getSelection().length>3)
}
