Overview of ASP. NET data binding web server controls

Gridview Control

Gridview
Controls display data in the form of tables, and provides the ability to sort columns, read data, and edit or delete a single record.

:
The gridview control is DataGrid provided in earlier versions of ASP. NET Controls. In addition to adding new features that utilize the data source control function, the gridview Controls also implement some improvements, such as defining multiple primary key fields, using bound fields and templates to improve user interface customization, and using new models to process or cancel events.

Control and Comparison
The gridview and DataGrid web server controls.

 

The data source value is displayed in the table. Each column represents a field, and each row represents a record. Use the gridview control to select and edit
Sort these items and sort them.

Detailsview Control

Detailsview
Controls display records in the form of a table at a time, and provides the ability to read multiple records and insert, update, and delete records. Detailsview

The control does not specify the predefined layout used to display records. In fact, you will create a template containing the control to display each field in the record. This template contains the format, controls, and binding expressions used to set the form layout.

Function:

Bind to a data source control, such as sqldatasource and objectdatasource.

Repeater control

Repeater
The control displays the read-only list using a set of records returned by the data source. And formview
Similar to controls, Repeater
The widget does not specify the built-in layout. You can use the template to create a repeater
Control layout.

Control.

 

A data binding list control allows you to customize the layout by repeatedly specifying each template displayed in the list.
The Repeater control is a list of basic template data bindings. It does not have a built-in layout or style, so it must be displayed in the template of the control
Declare all la S, format settings, and style tags.

The Repeater control is the only web control that allows tags to be split between templates. To create a table using a template, go to headertemplate
Including the table start mark (<Table>), including a single table row mark (<tr>) in itemtemplate, and in footertemplate
Including the end mark of the table (</table> ).

The Repeater control does not have built-in selection and editing support. You can use the itemcommand event to process the control triggered by the template.

Controls display data in the form of tables. With this control, you can use different la s to display data records, such as arranging data records into columns or rows. You can
Allows you to edit or delete records in a table. (Datalist

Listview Control

Listview
Controls can display data from the data source in the format defined by the template. This template contains the formats, controls, and binding expressions used to set the data layout. Listview
Controls are useful for data in the repeat structure. They are similar to datalist and
