ASP MVC3 – Editing records with jQueryUI Dialogs and AjaxForms – Razor Version

This post is in response to the several requests I’ve gotten to provide a Razor version of a sample solution I provided a few months ago on Editing records with jQueryUI Dialogs and AjaxForms, which was originally posted using aspx views. If you haven’t read it or seen the video, please take a look at it first; as most of the concepts will remain the same. .

So this solution is practically unchanged compared to the original, however I did I introduced 2 improvements (which could also apply to the aspx version).

  1. I realized after I did my original post that I was able to get data on the handler function from the ajax form; so I am no longer looking into the response div for my data (which was kind of a hack). Instead I am now using it properly by receiving the data directly.
  2. I use a JsonStandardResponse, which I have been using in my projects succesfully and make things a bit easier. (See my previous post: Json Standard Responses for your Ajax Calls). So the controller action was changed to return JsonResult instead of a regular ActionResult with Content.
Here are the details of the change in the controller:
[HttpPost]
public JsonResult Edit(CarModel model) {
if (ModelState.IsValid)
{
CarModel car = CarRepository.GetCars().Where(c => c.Id == model.Id).FirstOrDefault();
car.Name = model.Name;
car.Description = model.Description;
return Json(JsonResponseFactory.SuccessResponse(car),JsonRequestBehavior.DenyGet);
}
else {
return Json(JsonResponseFactory.ErrorResponse("Please review your form"), 
            JsonRequestBehavior.DenyGet);
}
}

ASP MVC3 – Editing records with jQueryUI Dialogs and AjaxForms

In this screen cast I will show you a demo of how to use  jQueryUI dialogs and MVC AjaxForms to create a rich and simple experience for users when editing records.

The technique is simple; you dynamically load a partial view into the DIV dialog  . There are a few tricks to wire up the validation, and to identify success over failure. .

Get the source code by clicking here, take a look and let me know what you think.

Update: 

After many requests, I’ve created a Razor version, all interested can read the post here. 

In case you missed it: App_Offline.htm

I recently found out about a featured introduced in ASP.Net 2.0 that makes it pretty easy to take your application offline, which is pretty useful for when you are doing upgrades, releases, etc. I’m not sure how I missed this as it has been out there for at least a couple of years, but still wanted to do a post about it in case other people missed it as well.

Extension Gallery

It is now simpler than ever to extend VS2010 functionality. On the Start Page, you will find a link to the extension gallery where you will be able to download extensions both free and commercial.

I already used it, I was able to find a OpenId template from the gallery, installed it and used it immediately. Continue reading “Notes form Visual Studio 2010 At the Movies event (Part 2)”

MS BizSpark – Good move to get Start-ups

Starting a company is a lot of work… and expensive! Usually you gave up a steady income to go an do your own thing, and the expenses and costs can creep up very quickly.

For developers on  Microsoft’s technologies, and in general for most start-up, it was always been hard to come up with the money for the MSDN Subscription that can be up to 6K a year. Company with competitive technologies which are open source, this is a major disadvantage for MS.

On top of this, if you developed your site on microsoft’s technologies, shared hosting was always much  more expensive for licensing issues.

Well, it seems that MS has noticed they are loosing too many start ups and are doing something about it…
