Hi @Bob Dang ,
The DetailView is a data control. Of course the purpose is to show the data from the data source. You could try to bind the source to see the layout. It only show one single record. When you bind the datafield, there are two ways: one is using BoundField. Because the detailview have the table layout, you only bind the DataField on the BoundField. Another way is using the templatedfiled. You could create the template by yourself. I suggest you could learn this article.

What is a data control in the highlighted image? What do you mean by it only shows one single record in the highlighted part of the image, since I thought that it can show many records? What do you mean by you can only bind the datafield on boundfield?

Thanks for your help.

Hi @Bob Dang ,

What is a data control in the highlighted image?

In the asp.net, the control have many groups:
1.Standard Controls: Enable you to render standard form elements such as :label, textbox, dropdownlist
2.Validation Controls: Enable you to validate form data before you submit the data to the server such as: RequiredFieldValidator
3.Rich Controls:Enable you to render things such as calendars
4.Data Controls.Enable you to work with data such as database data. For example, you can use these controls to submit new records to a database table or display a list of database records such as DetailView.
There are many other groups. I suggest you could read some articles or you create a webform by yourself. You could find them in the toolbox.

What do you mean by it only shows one single record in the highlighted part of the image, since I thought that it can show many records?

I have replied in your other thread about formview. It's same with the detailview.

What do you mean by you can only bind the datafield on boundfield?

You could see the article I have post to you. You could click the link at the "article". BoundField is the field in the DetailView. And the dataField is the property of the BoundFiled.

You can only really understand everything if you read the basic knowledge and write the codes by yourself.
