Multiple file upload with asp.net mvc and HTML5

Few days I have written a blog post about Multiple file upload with asp.net 4.5 and Visual studio 2012. It was greatly appreciated by the community and also been part of www.asp.net community daily spot light.  On that post one of my reader Ciwan Kurd has requested the asp.net mvc version of that post. So in this post I will explain how we can do multiple file upload with HTML5.

For this post I am going to use asp.net mvc 3 with HTML5 template and visual studio 2012 but you can use same techniques in any version of asp.net mvc.  First things we needs to do create a HTML form for the uploading file in asp.net mvc view so following is a code for that.

@using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{ 
    <label for="file">Upload Image:</label>
    <input type="file" name="files" value="" multiple="multiple"/>
    <input type="submit" value="Upload Image" />
}

In above code that I have use @HTML.BeginForm to create a HTML form with multipart as this attribute is required to upload any kind of files on the server. I have mapped that form to upload action result. Also I have used the file input control with HTML5 multiple attribute which allow us to upload multiple files on the server. Now its time to write code in asp.net mvc controller. Following is a code for that.

Model binding with ASP.NET 4.5 and Visual Studio 2012

Note:I have written a whole series of Visual Studio 2012 features and this post will also be part of same series. You can get the whole list of blogs/articles from the Visual studio 2012 feature series posts there. Following is a link for that.Visual Studio 2012 feature series

In earlier version of the asp.net we have to bind controls with data source control like SQL Data source, Entity Data Source, Linq Data Source if we want to bind our server controls declaratively. Some developers prefer to write whole data access logic and then bind the data source with databind method. Model binding is something similar to asp.net mvc binding.

Model Binding in ASP.NET 4.5 and Visual Studio 2012:

With ASP.NET 4.5 and Visual studio 2012 we have a new method of binding data called ‘ Model binding’. It’s a code focus approach of data binding. Now all the controls will have ItemType property which will implement strongly type binding. The server controls will then call appropriate methods at the proper time in page life cycle and bind the data.

So what we are waiting for ? let’s take one example. First we need to create a model. For the this I have created a model class called ‘Customer’. Following is code for that.

Dividing web.config into multiple files in asp.net

When you are having different people working on one project remotely you will get some problem with web.config, as everybody was having different version of web.config. So at that time once you check in your web.config with your latest changes the other people have to get latest that web.config and made some specific changes as per their local environment. Most of people who have worked things from remotely has faced that problem. I think most common example would be connection string and app settings changes.

For this kind of situation this will be a best solution. We can divide particular section of web.config into the multiple files. For example we could have separate ConnectionStrings.config file for connection strings and AppSettings.config file for app settings file.

Most of people does not know that there is attribute called ‘configSource’ where we can  define the path of external config file and it will load that section from that external file. Just like below.

<configuration>
 <appSettings configSource="AppSettings.config"/>
 <connectionStrings configSource="ConnectionStrings.config"/>
</configuration>

And you could have your ConnectionStrings.config file like following.

Event handler generation in Visual Studio 2012

Note: This post will be a part of Visual Studio 2012 feature series.

There are lots of new features there in visual studio 2012. Event handler generation is one of them. In earlier version of visual studio there was no way to create event handler from source view directly.  Now visual studio 2012 have event handler generation functionality.

So if you are editing an event view in source view intellisense will display add new event handler template and once you click on it. It will create a new event handler in the cs file. It will also put a eventhandler name against event name so you don’t need to write that.

So, let’s take a simple example of button click event so once I write onclick attribute their smart intellisense will pop up
.


Now once you click on <Create New Event> It will create event handler in .cs file like following.
