Introduction
Here is Part 1
Toolbox is very-very important building block of .NET Framework. Toolbox is an
area where all the controls existed. It helps the developer to develop any
application very quickly, only drag the control from the toolbox and drop it on
the form. To change its properties we have to select the control and make the
properties changes from Properties window. We can do it manually by writing
code-behind. There are over 100 controls available in ASP.NET 4.0. I am listing
here all the controls available in ASP.NET 4.0 and writing some lines on each of
them.

2. Data Controls
Data Control section includes the controls which mostly let us to connect from
external databases. Means in this section we are going introduce about all
controls which have ability to leads the databases on web page. There are mainly
two types of control we will find here that is DataSource Control and Data
Control. For example DataSource Controls includes controls like EntityDataSource,
LinqDataSource, ObjectDataSource, SiteMapDataSource, SqlDataSource,
XmlDataSource and Data Control includes recent all excluding pointer as listed
below.
- Pointer: It is just a pointer. If we drag any other control on form it
causes to create that control on form but pointer does not create any control on
form. In other word we can say, we select it for to ignore any other selected
control.
- AccessDataSource: This control is used to connect the Microsoft Access
Databases. We can say this control is derived from SqlDataSource, which has
complete connection string like credentials, path etc but AccessDataSource has
only its MDB database path.
- Chart: This control is used to create professional looking data
visualization charts. It is mostly used in windows based applications. We have
35 types of chart in .Net 4.0 with fully 3D support.
- DataList: This control is used to list the data from database and it
looks like table on web form. We can select or edit any data Selection or
edition of any row is possible here.
- DataPager: This control is generally used with ListView control. As we
ListView control is data driven so we have to create ListView on web page first
and provide some data to it and now add DataPager control onto the page to
enhance web page functionality.
- DetailsView: This control is used to display, edit, insert, or delete a
single record at a time from its associated data source; it displays only a
single data record at a time, even if its data source exposes multiple records.
- EntityDataSource: This control is used to create, read, update, and
delete data like other data sources. It works like editable grids or say form
with lots of user controlled techniques like sorting, filtering etc.
- FormView: This control is similar to DetailsView control, which gives
us the ability to work with a single record from a data source. Main difference
between both controls is that DetailsView control uses a tabular layout where
each field of the record is displayed as a row. In FormView control we can
create template containing any other control.
- GridView: This control is used to displays data from data source in a
table. In table column represents a field and row represents a record. We can
select, edit or sort the data items here.
- LinqDataSource: This control is used to connect wide variety of data
sources that includes database data, data-source classes, and in-memory
collections. It also let us to specify database like retrieval tasks like
selecting, filtering, grouping, and ordering against all types of data sources.
We also use this control for updating, deleting, and inserting database tables.
- ListView: This control is used to display the data from database. It is
similar to GridView, Repeater and DataList, which also help us to display data.
List view control is template driven control.
- ObjectDataSource: This control is introduced in ASP.Net 2.0, which
helps us to connect with database using very less coding. In this control we use
TypeName property instead of using ConnectionString property in another data
source controls. It supports properties such as SelectMethod, UpdateMethod,
InsertMethod, and DeleteMethod etc.
- QueryExtender: This control is used to filer data from database without
using WHERE clause. As we know database filtering requires WHERE clause in
command.
- Repeater: This control is used to display a repeated list of items that
are bounded to the control. It may be bound to a database like XML file, or
another.
- SiteMapDataSource: This control is used to retrieve navigation data
from a site map provider that is from any data source using DataSourceID and
then passes the data to a control that displays that data such as the TreeView
and Menu controls. This is very informative for website visitors to find any
link in huge list of links.
- SqlDataSource: This control is used to control or access data located
in a relational database, including different database service providers like
Microsoft SQL Server and Oracle databases, as well as OLE DB and ODBC data
sources.
- XmlDataSource: This control is used to display XML data from XML
database. It usually used to display or read only XML data. User can edit,
delete and update XML data using XmlDataSource control only through some code.
Note1: Keep visiting to my articles, you will find different articles on
different controls separately in coming days.
Note2: Continue in next part.
