That was in the old ASP.NET pages. In ASP MVC you don't have a ViewState
, isPostBack
or runat="server"
you can pass variables from the controller to the view using ViewBag
and ViewData
like:
Controller:
ViewBag.Name = "My Name";
ViewData["Name"] = "My Name";
View:
@ViewBag.Name
@ViewData["Name"]
I don't think you need to do that. You can have a action that do the task that you need to get done and with JavaScript request that action via AJAX. You can then with JavaScript show and hide the loading as you wish:
function LoadAjax(containerId, url, params){
//Set loading in container
$(containerId).html('<img src="loading.gif" alt="loading"/>');
//Do the request
$.ajax({
type: 'POST',
dataType: "html",
url: url,
data: params,
success: function(data){
// show response inside container (removes loading)
$(containerId).html(data);
},
error: function( jqXHR, textStatus, errorThrown){
// show error inside container (removes loading)
$(containerId).html(textStatus);
}
});
}
While the page is loading it will display the loading image. You will need Jquery to use my code. Hope it helps.
