I look a way to autoselect row with keyup and keydown (without press enter) in the grid element;
It would be convenient for me have an even like “focues-items-changed” just like selected-items-changed.
For now the only solution i have found is uncomfortable…
Is there a way to know when row get focus ?
Thanks in advance
p.s.
This is temporary solution that I found. Is there a better way to implement it ?
//grid is vaadin-grid polymer element
grid.addEventListener('keyup', function(e) {
var i=grid.selection.selected()[0]
;
if (i===undefined) {
grid.selection.select(0);
return;
}
if (e.code=="ArrowDown") {
if (i==grid.items.length) return;
i++;
grid.selection.select(i);
}
if (e.code=="ArrowUp") {
if (i==0) return;
i--;
grid.selection.select(i);
}
//TODO: handle PageUP and PageDown
});
Is there a way to know when the focus of a line change?
