#Remarks
Handle the KeyUp
event to process release actions for specific keys. To get information on the released key (for instance, its key or code value), use the e.htmlEvent property. You can also use the e.keyCode event property to get the key code as an integer value.
In the example below, ASPxGridView collapses all expanded group rows when a user releases the custom Shift
+Space
shortcut (the Space
key’s integer code is 32).
var spaceKeyCode = 32;
function onKeyUp(s, e) {
if (e.isShiftPressed && e.keyCode == spaceKeyCode) {
s.CollapseAll();
}
}
