Gridpanel - Hide store records
Hi guys,
I would like to request for a little help here.
How can I hide multiple rows based on an simple array?
I tried several methods, none of them worked well, I know I have to apply multiple filter for a column... but don't know how.
It would be nice if I press the button (btnFilterItems), then my Store1 get's filtered for the array items.
Please check out the example and help me if you have a working solution/tip/info!
Thanks in advance,
