View Full Version : [CLOSED] Combobox items

Apr 01, 2015, 1:48 PM
I have a form with few combo boxes which have considerable number of list items. If I fill all of them in advance it takes some time until form is opened. The thing is that they must not be filled at all, only if user wants. I would like to speed up the rendering of the form by filling items of combo box on demand (like event type in, or click on arrow). Is this possible?

Hmmm the moment I posted question, I came to idea :). It is possible by using Store (instead of items) and set AutoLoad to false and then on Expand handler just reload store. Thanks

P.S If there is better idea please propose, otherwise you may close this thread :)

Hi @ingbabic,

Exactly, remote loading of items on demand appears to be the only solution.
