MVC3 - Ajax loading icon

Question

I would like to show an AJAX loading icon during an ActionResult request that can take a few seconds to process.

What is the best approach to accomplished this?

Answer 1

Put the image in a div tag like this:

and then create your link like this:

@Ajax.ActionLink("Link Text", "ActionName", "ControllerName", null, new AjaxOptions { LoadingElementDuration = 1000, LoadingElementId = "busyDiv", HttpMethod = "Post", UpdateTargetId = "targetDiv", OnFailure = "PostFailure", OnSuccess = "PostSuccess", OnComplete = "PostOnComplete" }, null)

or in a form do this:

@using (Ajax.BeginForm("TestAjax", new AjaxOptions { LoadingElementDuration=1000, LoadingElementId="dave", HttpMethod = "Post", UpdateTargetId = "targetDiv", OnFailure = "PostFailure", OnSuccess = "PostSuccess", OnComplete = "PostOnComplete" }))

Obviously omitting those AjaxOptions that you don't need, as per the documentation here: http://msdn.microsoft.com/en-us/library/system.web.mvc.ajax.ajaxoptions.aspx
