[SOLVED] TableView remove all selected items

[levelxxl]

Hi,

I can't figure out how to remove all selected items of a TableView, when using SelectionMode.ExtendedSelection.

There is a forEach function in the Selection, but this only iterates over the selection from the begining. The problem is, when doing

@tableView.selection.forEach( function(rowIndex) { model.remove(rowIndex) } )@

the first item gets removed, and all following rowIndex values are wrong.

Has someone a simple solution to this?

Thanks

Hi,

You would need to start from the last selection element and go back to the first

Hope it helps

I know, but what I don't know is how to sort the selection.

Is there a way to get the range of the selection as an array?

The problem is, that when you use SelectionMode.ExtendedSelection, you can select random items. They don't have to be consecutive.

Thanks

Are you sure that even if randomly selected, the order of the index returned by selection is the same ?

I have found a solution. You have to use the private __ranges array of the selection object.

Here is my solution:

@
function removeSelectedRows() {
for (var i = selection.__ranges.length - 1 ; i >= 0 ; -- i) {
var index = selection.__ranges[i][0];
var count = 1 + selection.__ranges[i][1] - selection.__ranges[i][0];
model.remove(index, count)
}
selection.clear()
}
