Adding an AJAX progress panel

Yehuda Lando asked on June 25, 2014 16:39

Hi,

In some of my pages, I use AJAX panels around my web parts.

Is there a way to hook an update progress panel to them so it will show up when making an AJAX request?

Thanks, Yehuda

I found how to do this. I added this script:

// Get the instance of PageRequestManager.
var prm = Sys.WebForms.PageRequestManager.getInstance();
// Add initializeRequest and endRequest
prm.add_initializeRequest(prm_InitializeRequest);
prm.add_endRequest(prm_EndRequest);

// Called when async postback begins
function prm_InitializeRequest(sender, args) {
    // get the divImage and set it to visible
    var panelProg = $get('loader');
    var el = $get(args._postBackElement.id);
    panelProg.style.display = '';
    panelProg.style.position = 'fixed';
    panelProg.top = el.offsetTop;
    panelProg.left = el.offsetLeft;
}

// Called when async postback ends
function prm_EndRequest(sender, args) {
    // get the divImage and hide it again
    var panelProg = $get('loader');

    panelProg.style.display = 'none';
    panelProg.style.position = '';
}

And I added a div like this:

<div id="loader" style="display:none;">
    <div class="circle"></div>
    <div class="circle1"></div>
</div>      

And styled it with some css3 animations
