选择鼠标/将焦点放在文本框VB.NET上时，突出显示窗体中的文本框

Question

I want to ask if how could I change a textbox color when I highlighted for each textbox in form controls.

For example if I have 50+ textbox, its really hard for me to code 50+ textbox each right?

So is there anyway I could set this in a single function?

Any help is appreciated.

Thanks,

Alvin.

Answer 1

Just make a new class and inherit from textbox. Alter the events in your textbox class and use it instead of the normal textbox.

Public Class MTB
Inherits TextBox

     Private Sub MTB_GotFocus(sender As Object, e As EventArgs) Handles Me.GotFocus
           BackColor = Color.Aqua

     End Sub
End Class

After you rebuild the project, the MTB object will be waiting for you in the toolbox.
