Data Source and Field - Solved (Not with data source)
How can i set the data source and data field to textboxes on VB.net???

in VB6 i used to do:
VB Code:
```
txt_user.DataSource = rs
txt_user.DataField = user
```
Thank you,
Guilherme

In .NET , I think it's similar to this .
VB Code:
```
TextBox1.DataBindings.Add(new Binding("bind",ds,"table")
```

Do not use binding. it sucks and will cause you headaches later.

I agree this time . But I tried to answer the guy whether I like or dislike binding .Do your work in code .

use code or iterate the control you'd like with the data in the database or whatever .

Dude , that's old-fashioned model . In .NET ADO.NET is super cool . Just give it a chance you won't regret it .

have a class that does all your data access and then returns another class that represents wha you are working on.

Then you change values of controls based on this object:

txtFoo.text = myObject.PropertyFoo

Then if someone changes txtFoo you do this:

myObject.PropertyFoo = txtFoo.text

and pass the object back to your data access class that takes the changes and persists them to the database.

Databinding is WAY slower than manually doing it. Thing of all the crap that has to be tracking doing it automagically by the run time vs you managing it via code.
