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.

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.

Multiple file upload with asp.net 4.5 and Visual Studio 2012

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

In earlier version of ASP.NET there is no way to upload multiple files at same time. We need to use third party control or we need to create custom control for that. But with asp.net 4.5 now its possible to upload multiple file with file upload control.

With ASP.NET 4.5 version Microsoft has enhanced file upload control to support HTML5 multiple attribute. There is a property called ‘AllowedMultiple’ to support that attribute and with that you can easily upload the file. So what we are waiting for!! It’s time to create one example.
On the default.aspx file I have written following.

<asp:FileUpload ID="multipleFile" runat="server" AllowMultiple="true" />
<asp:Button ID="uploadFile" runat="server" Text="Upload files" onclick="uploadFile_Click"/>

Here you can see that I have given file upload control id as multipleFile and I have set AllowMultiple file to true. I have also taken one button for uploading file.For this example I am going to upload file in images folder. As you can see I have also attached event handler for button’s click event. So it’s time to write server side code for this. Following code is for the server side.

protected void uploadFile_Click(object sender, EventArgs e)
{
    if (multipleFile.HasFiles)
    {
        foreach(HttpPostedFile uploadedFile in multipleFile.PostedFiles)
        {
            uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),uploadedFile.FileName));
            Response.Write("File uploaded successfully");
        }
    }
}

Note: I have been writing a series of posts about Visual Studio 2012 features. This series describes what are the new features in the Visual Studio 2012. This post will also be part of Visual Studio 2012 feature series.

As we know now days web applications or site are providing more and more features and due to that we have include lots of JavaScript and CSS files in our web application.So once we load site then we will have all the JavaScript  js files and CSS files loaded in the browsers and If you have lots of JavaScript files then its consumes lots of time when browser request them.
Following images show the same situation over there.



Here you can see total 25 files loaded into the system and it's almost more than 1MB of total size. As we need to have our web application of site very responsive and need to have high performance application/site, this will be a performance bottleneck to our site. In situation like this, the bundling feature of Visual Studio 2012 and ASP.NET 4.5 comes very handy.

Suppose we have long HTML mark up and we need to convert one div to user control and then we can do it very easily with Visual Studio 11 beta Extract to User Control feature.

You just need to select code you want there in user control and then you need to right click and click ‘Extract to User Control’ like below.
