Hi.
I need to have the load-on-demand feature like the listbox in my combobox.
Listbox load-on-demand
And I don't want to use the bandbox sample :
bandbox as combo box
I know the autocomplete feature and the ListModels.toListSubModel list model that loads only some of the items.
but this is not enough.
Hi
I think my question has no enough details.
I have a combo box that its data count is over 1000 items.
so for loading the page, it takes a lot of resource of the client.
the combo items, are provided by a ListModelList.
when I open the combo, it takes a lot of time to open, and some times the browser hangs and I have to close it.
so I need a way to load the items partially, not all at once.
I tried the autocomplete feature and the ListModels.toListSubModel but my problem is that in this way, the combo only loads 15 items at once, and I can not see the other items.
I need a way that tells the combo load 15 items (for example) at once, and if the user scrolls down, load the next items.
the examples that I found in the ZK demo are not what i need.
in both of them I can not use the combobox component, but I need to use it.
so any idea?!
I have a feature request to add a setter for data in SimpleListModel, i.e. this field:
private final Object[] _data;
I think it might be relevant in your case, too. http://tracker.zkoss.org/browse/ZK-795
Hi Richard
I red the links, but my problem is not fetching the data. I don't need to fetch the data in pages.
As I mentioned before, the "ListModels.toListSubModel " works fine, but the problem is that the solution is linited in items count, and I need to load more data when scrolling down or up.

Hi
if you use ZK EE version, Combobox won't create comboitem when loading page, so the loading time is short
I tested it use the code below
<window title="Test" border="normal">
<zscript><![CDATA[
List strset = new ArrayList();
for (int i = 0; i < 1000; i++) {
strset.add("" + i);
}
]]></zscript>
<combobox>
<comboitem label="item ${forEachStatus.index}" forEach="${strset}"></comboitem>
</combobox>
</window>
it will create comboitem when user click the combobox's button
