How to Bind an Object to TextBox

Binding Objects to Windows Form Controls

Here is a simple example to bind a object to textbox control

Let us have a small form with two Textboxes, a label and a button

We also have a class that has two properties - Name of Company and the Business they are involved. Here is how the class looks

Public Class ClassDataBind 

Private sPrvName As String 

Private sOfferings As String 

Public Sub New(ByVal sName As String, ByVal sOffer As String) 

Me.Name = sName 

Me.Solutions = sOffer 

End Sub 

Property Name() As String 

Get 

Return sPrvName 

End Get 

Set(ByVal value As String) 

sPrvName = value 

End Set 

End Property  

Let us now Bind the class to the text boxes using

Private Sub FormDataBind_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 

oDataBind = New ClassDataBind("Accenture", "Consulting") 

TextBox1.DataBindings.Add("Text", oDataBind, "Name", True, DataSourceUpdateMode.OnPropertyChanged) 

TextBox2.DataBindings.Add("Text", oDataBind, "Solutions", True, DataSourceUpdateMode.OnPropertyChanged) 

End Sub

Once the binding is done , run the code to view how it looks :

Since the text boxes are bound to the Objects and we have set the Objects to be refreshed we can change the contents in textboxes and see if the Objects are refreshed.

Private Sub ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 

Label1.Text = oDataBind.Name + " - " + oDataBind.Solutions 

End Sub  

You can now save the object back to DB etc if needed. If you don;t want to update certain field. For example, the company name here - you can do the following:
