Question

How to show the indeterminate progress bar on top of the page while Winjs.UI.ListView fetching the data. Is there any built in feature to show the progress in Winjs?

Answer 1

Let’s say the method where you fetch your daya is getData().

function getData(){
var progress = document.createElement("progress");
document.getElementById("someDiv").appendChild(progress); //we have created and appended an undetermined progress bar.
//do the data fetching, and, when it's over and ítems have been asigned to the ListView remove the progress element from the div.
}

Otherwise, in HTML:

<progress></progress>
