The GridView in this example is paging enabled. The data binding of the GridView control will be done using code behind procedures. Net using DataTable - C and Vb. The DataSet class is defined in the System. Data namespace in the. Net framework.
Therefore, you need to add the namespace in the beginning of the code. When the form loads, I am calling a private procedure that will create a connection to an SQL Server database and table. Once I have successfully set the connection, I am declaring and initializing a DataSet object. This class represents a set of data commands and connection that are used to fill the DataSet.
The DataSet object now has the data extracted from the database table. Now, you can bind it with GridView control. The DataSet is a core component in the. It has its benefits and some limitations. However, it is useful when you want to share data across multiple pages using Session without repeatedly setting a connection to the database.
A DataSet represents a set DataTable objects.

Its like a mini database that does not need an active connection with the database. A dataset object has many benefits. The examples are in C and VB.
Data; using System. Open ; sda. Option Explicit On Imports System. Imports System.A grid for ASP. Also has filtering support, export to csv, back button support, and graceful degradation. The primary goal of this project is to provide the core grid functionality, along with a very simple and easy-to-use client-side API to allow you to easily add the additional front-end interaction you need.
You can add it to your project very easily and get it running with minimal effort, but it also has the extensibility to customize when needed. You configure your grids on app start, and provide a function callback to actually query your data. The library will handle the ajax requests.
It will parse and validate the requested options and then pass the QueryOptions to your function to retrieve the data. Net A grid for ASP. Features Uses your existing model objects Server-side sorting and paging using AJAX updates query string to support maintaining grid state when navigating back gracefully degrades on older browsers works on IE8 Built-in exporting to csv Filtering and column visibility support with minimal client-side code Example Page Size: 10 25 50 There was a problem loading the grid.

In web application, displaying data in a gridview is a common requirement. Hence, we will walkthrough possible ways of designing grid view in ASP. I will show an example product list class which is used for demo at the end of this article. Action method: From the below code, GetSampleProducts method is used to take sample product records which I'll show at the end of this article.
Apart from that, rest of the code is only for pagination. Linq's Skip and Take method : In order to implement pagination, we have to fetch records in a part instead of complete records. Take is similar to top from SQL query, it is used to take exact number of records.
Combining both methods, see the below example. View Page : Look at the foreach code. Products list is being iterated to display all the rows. Css class "table table-bordered" is used which is from bootstrap. It was introduced in MVC 4, prior to that, there was no way of doing it but to adapt any third party plugin or designing grid yourself.
Webgrid displays records in tabular format. In other words, what we have seen in the above example, looping list class and making grid design, this is internally done in WebGrid helper class. The advantage of using WebGrid is, it supports inbuilt sorting, paging, filtering and ajax update. Here is the example. Action Method: Only additional changes in this action method from the above example is that we are assigning total count in model's properties.
View Page : We are initializing WebGrid object and binding it while passing product list class. Once binding has been done, we can get html of grid using GetHtml method. You can customize column name using grid. Columnalso see the last column from the below example how I have added edit link button. Helpers reference manually. After adding the reference, right click on it, select properties and change ' CopyLocal ' to True.

NET development for a little while now, and I've used both the GridView and the DataGrid controls before for various things, but I never could find a really good reason to use one or the other.
I'd like to know:. What is the difference between these 2 ASP.
NET controls? What are the advantages or disadvantages of both? Is one any faster? Easier to maintain? The intellisense summary for the controls doesn't seem to describe any difference between the two. They both can view, edit, and sort data and automatically generate columns at runtime. Edit: Visual Studio no longer lists DataGrid as an available control in the toolbox. It is still available for legacy support I assume if you type it in by hand though.
DataGrid was an ASP. NET 1. GridView arrived in 2. The GridView control is the successor to the DataGrid control. When bound to a data source, the DataGrid and GridView controls each display a row from a DataSource as a row in an output table. Although it has a similar object model to that of the DataGrid control, the GridView control also has a number of new features and advantages over the DataGrid control, which include:.
Differences between the GridView control and the DataGrid control include:. Sorting, paging, and in-place editing of data requires additional coding when using the DataGrid control.
The GridView control enables you to add sorting, paging, and editing capabilities without writing any code. Instead, you can automate these tasks, along with other common tasks such as data binding to a data source, by setting properties on the control. The DataGrid was originally in. The GridView was introduced and replaced the DataGrid in. NET 2. They provide nearly identical functionality.
NET 3. Use the ListView - it gives you the features of the GridView combined with the styling flexibility of a repeater.
NET Web Application. Project Structure. We are going to add Customer Model to the Models folder. After adding model next, we are going to use Entity framework for accessing database to doing that we need to setup DbContext class. We are going create this class in Model Folder. DBSet class represents an entity set that is used for creating, read, update, and delete operations.
After we have clicked on Add button, it has created DemoController in Controller folder, as shown in the below view. DataTables Options snapshot. And the main option is Ajax which we are going to use for calling an Action Method for getting data to bind DataTables Grid the data is in Json format. And data type we are going to set as Json. Finally, the second to last option is columns which are used for initialization of DataTables grid.
Add that property which you need to render on the grid, which must be defined in this columns option. At last, we need to render button in the grid for editing data and deleting data. In this action method, we are going to get all Customer records from the database to display and on the basis of the parameter we are going sort data, and do paging with data. We are doing paging and filtering of data on the server side; that why we are using IQueryable which will execute queries with filters on the server side.
For using OrderBy in the query we need to install System. Dynamic package from NuGet packages. Snapshot while adding System. After adding the package, next, we see the complete code snippet and how to get data and do paging and filtering with it.
All Request.A data bound list control that displays the items from data source in a table. The DataGrid control allows you to select, sort, and edit these items.
A Visual Studio Web site project with source code is available to accompany this topic: Download. The following code example demonstrates how to use the DataGrid control to display the items in the data source. The following code example demonstrates how to use the DataGrid control for a simple shopping cart. Before you use the DataGrid control, consider using the GridView control instead. The GridView control, which was introduced in the. NET Framework version 2. Use the DataGrid control to display the fields of a data source as columns in a table.
Each row in the DataGrid control represents a record in the data source. The DataGrid control supports selection, editing, deleting, paging, and sorting. This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application.
Validation server controls are also provided to assess user input. For more information, see Validation Server Control Syntax. Different column types determine the behavior of the columns in the control. The following table lists the different column types that can be used. By default, the AutoGenerateColumns property is set to truewhich creates a BoundColumn object for each field in the data source. Each field is then rendered as a column in the DataGrid control in the order that each field appears in the data source.
