Data binding technology is the basic and the most important part of data programming with .net programming language. It is the basis of adding, deleting, browsing, modifying and other operations to the records in the database. Although the approach to data binding varies for different WinForm components, it is more or less the same in general.

In the whole VB.NET data binding, different components can be roughly divided into two categories, one is simple data binding, the other is complex data binding. Simple data is aimed at TextBox components, Label components, etc., and there is only one record displayed by bound components, while complex objects are ListBox components, TreeView components, etc., and there are often more records displayed after binding.

1. Data binding of TEXTBOX

TEXTBOX1.DataBindings.Add

(property name, dataset_system.Tables

(Company), dataset_system.

Tables ("Company") Columns.

Item (I) .Caption)

Second, ListBox is bound to the number of ComboBox

The three properties are "DataSource", "DisplayMember" and "ValueMember".

"DataSource" is the specified dataset

"DisplayMember" is the field value displayed by the ComBox component

"ValueMember" is the selected value of the ComBox component.

Me.ComboBox1.DataSource =

Dataset_system.Tables ("Table name")

Me.ComboBox1.DisplayMember = "Field name 1"

Me.ComboBox1.ValueMember = "Field name 2"
