Do we speak about a customized Control ?

hemendrapadia 23-Jun-15 13:38pm

Simple native vb.net controls. No customized control

hemendrapadia 23-Jun-15 13:34pm

no no customized control

If you want to change the functionality or the behavior of a Control you need to customize it and add the "missing" function to your new own Control - that would be OOP.
Do you want to do it like this ?

yes, i simply not want to write in each and every control's event.
I know about -enter- and -leave- event but it could be generalized.
Even i use theme window all display styles of controls decided there in that window(form)

In the Moment I don't know how to help you.
But as Information : The Control-Events are made for this - to give you the possibility to customize (in other words : make your own) the functions.

But you are right : you could also do this on the Form (by using the same Events and working with the Sender of the Event) - but if that is a generell function for you, you should think about my Suggestion.
There is nothing, which speak against, that the Control itself know what to do ...

It's your turn ...

Even in VB6 that was a bad solution. Use the got focus and lost focus events.

hemendrapadia 23-Jun-15 14:17pm

yes you are right. That is why i plan to change the code.

Okay so go ahead and do that. I am not seeing where you would have any kind of a problem.

Howdy,
For starters you can create controls that have the behaviors you need, here is a small example:

VB

Public Class myTextBox
    Inherits TextBox

    Private Sub myTextBox_GotFocus(sender As Object, e As EventArgs) Handles Me.GotFocus
        BackColor = Color.White
        ForeColor = Color.Black
    End Sub
    Private Sub myTextBox_LostFocus(sender As Object, e As EventArgs) Handles Me.LostFocus
        BackColor = Color.FromArgb(255, 240, 240, 240)
        ForeColor = Color.FromArgb(255, 165, 165, 165)
    End Sub
End Class

Also, after you have rebuilt the solution this control will show up at the top of the Toolbox area. You can then select, drag and drop this on to your form. Although this is far from a complete example, it is easy enough to make a solution that works well with the events and actions of the Windows environment.
