Then analyze the principle of ADO.NET DataGridView control
This article will explain in detail for you and then analyze the principle of ADO.NET DataGridView control, the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.
We know a lot about the five objects in ADO.NET, and we have introduced them in detail before. here, let's discuss why we use DataGridView. Take a look at the following analysis. In the actual project research and development, we often encounter such a problem: how to efficiently display the data in DataSet objects?
There are several data tables DataTable in the DataSet object, and each DataTable object contains several DataRow objects that represent data records. This typical two-dimensional structural table information is obviously presented in the form of a spreadsheet. The application displays the data in the DataSet object by displaying one record at a time in the form, that is, one DataRow object content at a time. At this point, several controls display each field of the DataRow object, but only one record information can be displayed at a time. As shown in the figure:
A form diagram that displays a single record
But how can you display all the data records in a data table DataTable in a DataSet object on a single form interface? As shown in the figure:
A form diagram showing all records
The DataGridView control is used here, and only one DataGridView control can display all the data records in the data table DataTable. The work of the ADO.NET DataGridView control is shown in the figure:
The working diagram of the ADO.NET DataGridView control
As can be seen from the figure, a data table in the dataset DataSet can be displayed on a form interface, which is very convenient for users to view. From this, we can see the powerful aspect of the ADO.NET DataGridView control, which is mainly characterized by:
◆ displays data powerfully and flexibly
◆ easily defines the appearance of the control
◆ is as convenient as Excel tables.
◆ one line of code to implement data binding
◆ visualization operation
About then parsing the principle of ADO.NET DataGridView controls to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
