DGrid 'select all' checkbox is not working as expected

[andreayt1]

Is there an ability in DGrid to select all items from the onDemandGrid grid when a 'select all' checkbox been checked. I have used below selectAll function, and it is selecting only items loaded/displayed on the grid instead of all items. Using dgrid-1.2.1 version and dojo 1.14.1

selectAll: function () { this.allSelected = true; this.selection = {}; for (var i in this._rowIdToObject) { var row = this.row(this._rowIdToObject[i]); this._select(row.id, null, true); } this._fireSelectionEvents(); }

Any suggestions would help.

Sounds like you need to apply the selected to the underlying dataset, not the items in the rows of the component. Can you fire a command to set them to selected within your store?

Alternative hacky way: Create another hidden DGrid sharing the same dataset, with an infinite page size. The Select All checkbox can be connected to that DGrid...

With OnDemandList or Pagination the grid often only renders a subset of rows, which means that this._rowIdToObject is not going to map every data item to a row. As mentioned, you need to store the selection state on each item in the data and add some logic that synchronizes UI select events with the data.
