.NET Busy Indicator - User Take Any Action Before The End Of That Blcok Of Code?
Mar 4, 2011
I want a busy indicator i can use it in my asp.net application ... cause i have a block of code take time to execute and i want to let user take any action before the end of that blcok of code
Is there a way with ASP.net page (with AJAX) to display some some of busy indicator (just a label is fine) while disabling some buttons (to prevent double-click) and then do the work. At the end of the work, the label changes to indicate the new status. When I tried to do it this way :
Public Sub BtnEnvoyer_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnEnvoyer.Click BtnEnvoyer.Enabled = False LblStatus.Visible = True LblStatus.ForeColor = Drawing.Color.ForestGreen LblStatus.Text = "Envoi en cours..." SendEmail() End Sub Private Sub EnvoyerCourriel() ' Do some work LblStatus.Text = "Done!" BtnEnvoyer.Enabled = True End Sub
I just see the dn result, nothing in between. I don't mind using javascript to make it work if needed, or anything else for that matter.
I'm wondering about the underlying implementations of these design patterns specifically within asp.net. Is there a difference between the two models in terms of scalability of a website (i.e. as traffic increases might I regret following one or both of these design patterns)? I ask as someone once mentioned that MVC produces a 'lighter' website but I can find nothing to back this up.
If MVVM is as good as MVC why did MS release all the MVC tools?
I understand how to use javascript to change the cursor to busy while the page is making and ajax call. However I have a page that does not use ajax, it uses a postback to reload the page. However the load is rather data intensive and it takes a few seconds. During this time the user can still click on the page. I want to turn the cursor to "waiting" so the user does not try to click on the page. For example I have a couple of dropdowns that cause postback. I make a selection and the page loads for 3 seconds. While it loads I would like the cursor to turn to waiting so the user does not try to make a selection on a second dropdown until the page reloads. Is this possible?
Additional Info: (simplified version of my setup) I have a masterpage:
i use the code for my cascade dropdown list.my JResult function in cotroller doing some complex job.. ( i already fine tune it).based on that function my second dropdown list and some other controls values sets...now i want to show "busy icon" operation while this controller works in background
I am trying to validate an email address in a textbox, but when I try to type into the textbox, after I have typed more than about 10 characters, I get the Firefox error 'MicrosoftMvcValidation.js :29 Busy or stopped responding'. Here is my code,

( and use )Only by logged user with super Permissions?I would like to have a delete action link but I do not want all user to view this link (or to use)About the use I know I can use [Authorize] and declare the user but can I also hide the action link in the page?Or do I need (just for this to use area ?)
suppose my page content is huge so in my asp.net application i want to show busy icon with percentage downloading the content in client side. i saw many flash and sliver light site that they show busy icon and also they show percentage that means how much content has been loading in client machine. how could i achieve this using JQuery and when page content has been downloaded in client machine the busy icon goes out and actual page content will display.
I'm implement Comet in Asp.net MVC, I used timer to keep Async request in server, Async request will complete when timer elapsed 1 minute and response to client (to avoid 404 error) and then reconnect to Async Controller. I also wanna execute some Synchronous action during Async request was holding, but the problem is: When an Async action was executed and hold by using timer, the Sync Action wasn't called until Async action (comet long-live request) completed. I did test with firefox 3.6 many times, but the result is the same, so strange, Do you know why ? I have a sub some questions : To implement comet, using timer (response after some minutes elapsed) or thread (response after several time sleeping thread) to hold async request, which is better?
I am desiging a master and details page from a search page..user can search for something and I need to display the result in jqgrid if the result has more than 1 row or record.. if the result is just one record then i have to directly send then to details page by skiping grid page... I do have an action method for results page and one more action method for Jqgrid data..i am trying to check the row count for the database result and trying to redirect to details action results..but its not working at all..and showing an empty jqgrid..
Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller { public ActionResult Foo()[code].....
My httppost action doesnt seem to have received my model. The code is below;
[Code]....
i put a breakpoint on the line; return RedirectToAction("Error", "Dashboard"); and i found that appQualif carried no values whatsoever from the form i submitted..
Im using Gridview in my application ...when record(s) bind in the gridview i wnt to use indicator that is if i click first record of gridview then record indicator should be shown and every key down the record indicator should be down in every record ...
I've been using Html.Action("ActionName", "ControllerName") to invoke child actions across controllers without needing to have the view in ViewsShared. This has been working great for displaying things like session or cookie information.
Instead of just accessing cookies, I would like to pass additional parameters to Html.Action("ActionName", "ControllerName") so the action can execute different code based on the the data passed to the original view.
Should I be using a different method to pass parameters to a child action in a different controller?
I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?
