Client-Side Loading Icon

[digitall]

I have a treeview that expands with a ServerSideCallBack on certain nodes and shows the icon I setup inside <LoadingStatusTemplate>. Is there a client-side function I can call on a node that would show/hide this on demand? Something like "node.showLoading();" or "node.hideLoading();"?

Hello digitall,

Unfortunately we do not currently support the functionality that you mention in the forum thread. However, I will address your suggestion to our development team for a future consideration.

All the best,

I was able to find a workaround for this by using the showLoadingStatus method you expose and just forcing it to show an image:

function showNodeLoading(node) {
    var loadingImage = '<img src=\'/_assets/images/ajax-loader-small.gif\' alt=\'Loading..\' style=\'padding-left: 2px;\' />';
    if (node != null)
        node.showLoadingStatus(loadingImage, Telerik.Web.UI.TreeViewLoadingStatusPosition.AfterNodeText);
}
