Help
<combobox width="100%" autocomplete="true" model="@load(vm.streetList)"
selectedItem="@bind(vm.selectedStreetName.value)"
autodrop="true">
<template name="model"
var="each">
<comboitem
label="@load(each.value)" value="@load(each.value)" description="@load(each.label)"/>
</template>
</combobox>
Can anyone help me out to resolve that issue so that larger data can be loaded without any performance issue?
Hello psingh,
You could use a bandbox in order to control the number of records that will be displayed as shown below:

Hi Darksu,
In our case we can't use the bandbox,so please suggest any other solution.
18500 entries in a combobox? How is this supposed to make sense? How is anyone ever supposed to scroll through that? The best solution here is to choose (or code) a different way of input...

if you use ZK EE version, Combobox won't create comboitem when loading page, so the loading time is short, and it will not crash.
For example use the following code:
<window title="Test" border="normal">
<zscript><![CDATA[
List strset = new ArrayList();
for (int i = 0; i < 20000; i++) {
strset.add("" + i);
}
]]></zscript>
<combobox>
<comboitem label="item ${forEachStatus.index}" forEach="${strset}"></comboitem>
</combobox>
</window>
But again the data size is huge and will slow down the performance, thus please consider a different approach.
Best Regards,
Darksu
