+Naeem Ahmad Please visit www.questpond.com and mail to us on [e-mail]

[@monsieurrodriguez9687]

you didn't test the same name in the viewbag controllers communication example, at minute eleven, you put ViewBag.CurrentDateTime while actually it was named ViewBag.CurrentDateANDTime. Anyway, thanks for the video, the point was explained successfully

[@dpkbahuguna]

The session is very descriptive and informative to set the basics of MVC. Thanks...Keep posting the Training :-)

[@TubaMirza-co7ql]

11 years old video waw .. still knowledgeable

[@praveendubey1994]

Thanks , Awesome, Short, Simple and helps to understand exactly what is needed.

[@RaviHandsome]

Example is incorrect though concept is right. CurrentDateAndTime and CurrentDateTime are different at 12:20

[@wase39]

very simple and elegant lesson

[@rprabhuit]

wrong statement on TempData usage. TempData can be used from controller to view as well. The TempData will be reset to null, only after it was read or used. But we can keep the data's in TempData after read by calling TempData.Keep() function. The Keep() should be called immediately after TempData object used.

[@prateekbhardwaj9943]

+Prabhu Raja Exactly i was thinking the same.. but every where i read this that tempdata for controller to controller ... ? is it true for mvc 3? or in mvc 4 we can use controller to view (one cycle)

[@nimitjoshi8639]

I have worked on MVC 5 project and in that i have used TempData to pass the info from Controller to View.

[@mohamedsaied5780]

msdn.microsoft.com/en-us/library/system.web.mvc.tempdatadictionary(v=vs.118).aspx You can use a TempDataDictionary object to pass data in the same way that you use a ViewDataDictionary object. However, the data in a TempDataDictionary object persists only from one request to the next, unless you mark one or more keys for retention by using the Keep method. If a key is marked for retention, the key is retained for the next request. A typical use for a TempDataDictionary object is to pass data from an action method when it redirects to another action method. For example, an action method might store information about an error in the controller's TempData property (which returns a TempDataDictionary object) before it calls the RedirectToAction method. The next action method can then handle the error and render a view that displays an error message.

[@Nandakishore48]

yaa dude you are right

[@mohamedsaied5780]

yes, CurrentDateAndTime while in another CurrentDateTime but it will lead to null also if he typed it correct as viewbag cann't transfer data between controllers

[@218manish]

Nice & useful Tutorial

[@coolayer]

Thanks Brother! It was very helpful.

[@manoharjulakanti8688]

hi sir, i used temp data in view and also in action method ...then also data is transferring from action method to view.....

[@akashverma1640]

Sir at 12:07 you have used wrong name of variable in viewbag i.e viewbag.CurrentDateTime instead of Viewbag.CurrentDateAndTime that is why it's null.

[@bhuvanatn]

Thanks very much..very helpful

[@knowledgeys6652]

I believe Tempdata sends the data from one view to other View..

[@rohitshinde8145]

helpful ty.

[@prateekbhardwaj9943]

[@sinchanar440]

Sir, I have a question please give me a reply. How do I set session for multiple user login and I want to differentiate as Admin and local user...

[@RanjeetKumar-gg7ie]

through authorization differentiate between admin & local user , also set HttpContext.Current.Session.Timeout = x ,( x is time ) to set diff timeout as per user accessibility..

[@RanjeetKumar-gg7ie]

Create a master base class inherit it on master page if you are storing information in session about user type and write a function if(Session["admin"] !=null){ if(Session["admin"].ToString() == "True") { HttpContext.Current.Session.Timeout = 120; }if(Session["user"].ToString() == "True") {HttpContext.Current.Session.Timeout = 60; }else {HttpContext.Current.Session.Timeout = 30;} } or you can replace session with profile if you are using profile

[@amruthbinish]

how can we create mvc views faster and make them strong typed by using html helper ---where this video?

[@sujanvaland]

its not that we tempdata is not maintain from Controller to View, we can maintain the data

[@ragavaragala9116]

In action method samlpeview you mentioned current dateandtime but second action method you mentioned current datetime you don't mentioned and

[@tsogiaidze]

[@multanimohsin8800]

[@prashantkumar15689]

In case of view bag you set another variable and tried to get value from wrong variable. Don't try to confuse viewers and don't anything wrong. Concept is right what you said but demonstrated wrongly.

[@donfeto7636]

[@balaram438]
