Json + Drop down list

[naathaMember]

Hello,

I am populating my drop down list using the following code:

var source =
{
	datatype: "json",
	type: 'GET',
	url: 'Service.aspx/GetList',
	cache: false, 
	datafields:
	[
		{ name: 'ID'},
		{ name: 'City'}
	],
}
var dataAdapter = new $.jqx.dataAdapter(source, {
	contentType: "application/json; charset=utf-8",
	loadError: function (xhr, status, error) {
		alert(error);
	},
	downloadComplete: function (data, textStatus, jqXHR) {                    
		return data.d;
	}
});
$("#dropdownlist").jqxDropDownList({ source: dataAdapter, displayMember: "City", valueMember: "ID", width: '300', height: '25', theme: theme });

when the list items change in the server side, i want to fill the drop down list dynamically by using a refresh button.

How can i achieve this ?

for grid, i am using updatebounddata. Could not find anything for drop down list.

Thanks

Hi naatha,

To refill the DropDownList, you may call the dataAdapter’s dataBind() method. It will make another server call and automatically update the widget with the new data.
