How to refresh listView with Template

[Mike]

The below function reads from a specific URL and loads the contents into myDiv using a template and listView.  The function works perfect the first time.  How can I force the view to refresh with new data each time the function runs (the function is triggered externally)?

function loadNewFeed(url) {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: url,
dataType: "json"
}
}

});
$('#myDiv').kendoListView({
dataSource: dataSource,
template: kendo.template($("#reviewsTemplate").html())
});

};

I've been testing this issue further, and have found the following:

When the function first runs, it executes perfectly and renders the data via the template.

Upon subsequent runs the following javascript error occurs in Firebug:

Error: "b is null"

Script: kendo.all.min.js (line 8)

Can someone from Telerik, please respond and let me know if there is a solution to this issue?

thanks,

Hi,

Re-initializing the widget each time is not supported. You should create the datasource (and the widget) once, and then subsequently use the DataSource read method for data fetching.

Petyo,

Thanks for the info.  I tried using the read method, but it didn't work.  Using the above example can you give me an example of where/how to use the read method?

Thanks,

Hi,

Not really, as I don't see your project, and don't know what your business logic is. In general, you should call it where you are currently using the loadNewFeed. If need further assistance, I would like to recommend opening a support ticket with a sample project attached, so that we can assist you further. 

Kind regards,

OK, thanks.  I'll open a ticket momentarily.
