Our blazing fast Grid component built with pure JavaScript


Post by H9FFDC »

If you configure a grid with a checkbox selection mode, and group summaries, when you collapse or expand a group the checkbox may disappear. It appears that this will happen to any rows that collapse/expand to where a summary record would have been.

Can be replicated in this grouping demo.

  • Update the config to enable checkbox selection, and group summaries
  • Note that row 5 is an empty group summary row
  • Now collapse the first group
  • Row 5 is now a record with a missing checkbox
features : {
    sort  : 'age',
    group : {
        ...
    },
    groupSummary: true
},
selectionMode : {
    checkbox : true
},
