WebGrid is a helper introduced in MVC 4 which will let us render tabular data in a very simple manner. It has inbuilt support for sorting, paging, asynchronous updates via ajax and custom column formatting.

Following are the steps to implement WebGrid.

Step 1 - Create Model Data

First we need data which we will use to bind webgrid. We may get this as a model or may be as ViewData. In our case we assume that we will get as Model.

Step 2 - Make your view a strongly typed view

@model List

Step 3 - Create instance of WebGrid

WebGridMyGrid = new WebGrid(Model);

Write following code in your view,

Step 4-Render Grid

Write following code in your view,

@grid.GetHtml()

Output

CustomerId	CustomerName	CustomerAddress
1	A	AA
2	B	BB
3	C	CC

Customizing WebGrid

Paging - For that we will use overloaded version of webgrid constructor as follows,

WebGridMyGrid = new WebGrid(Model, rowsPerPage:3);

Output (considering we have total 10 records in the model)

CustomerId	CustomerName	CustomerAddress
1	A	AA
2	B	BB
3	C	CC
1 2 3 4 >

Customize columns - We will use overloaded version of GetHtml Method for that as follows,

@grid.GetHtml

(

columns:grid.Columns

(

grid.Column("CustomerId", "Customer Id"),

grid.Column("CustomerName", "Customer Name"),

grid.Column("CustomerAddress", "CustomerAddress")

)

Output

CustomerId	CustomerName	CustomerAddress
1	A	AA
2	B	BB
3	C	CC
