ComboBox delayed loading question

[alexzMember]

Hi,

I have common combo declaration and everything works fine. When page loads, combo immediately send request to remote url to populate itself. Can I change this behavior that request is send only when user opens the combo?

<script type="text/javascript">
	$(document).ready(function() {
		// TODO: get from user settings
		var theme = 'classic';
		// prepare the data
		var source =
		{
			datatype: 'json',
			datafields: [
				{ name: 'Id' },
				{ name: 'DisplayValue' }
			],
			url: '/Customers',
			data: {
				// TODO: parameter name that really works, maxRows is just default
				maxRows: 12
			}
		};
		var dataAdapter = new $.jqx.dataAdapter(source,
			{
				formatData: function(data) {
					data._q = $('#e592ee69-12fa-4eb6-9812-6e3120c96e43').jqxComboBox('searchString');
					return data;
				}
			}
		);
		$('#e592ee69-12fa-4eb6-9812-6e3120c96e43').jqxComboBox(
			{
				width: 250,
				height: 25,
				source: dataAdapter,
				remoteAutoComplete: true,
				theme: theme,
				selectedIndex: 1,
				displayMember: 'DisplayValue',
				valueMember: 'Id',
				renderer: function(index, label, value) {
					var item = dataAdapter.records[index];
					if (item != null) {
						var label = item.DisplayValue;
						return label;
					}
					return "";
				},
				renderSelectedItem: function(index, item) {
					var item = dataAdapter.records[index];
					if (item != null) {
						var label = item.DisplayValue;
						return label;
					}
					return "";
				},
				search: function(searchString) {
					dataAdapter.dataBind();
				}
			});
		
		
		$('#e592ee69-12fa-4eb6-9812-6e3120c96e43').bind('change', function (event) 
		{
			var args = event.args;
			if (args) {
				var item = args.item;
				$('#InvoicingCustomerId').val(item.value);
			}
		});
	});
</script>

Hello alexz,

Such feature is not available to jqxComboBox at the moment. However, we have created a work item on the matter and will consider implementing it in future versions of jQWidgets.
