Textbox will not fire the ONPaint

[christian ternek]

Hello !

I want to make a custom textbox and inherit a custom control
from textbox.

Now i want to change the looking of the textbox with the following code:
protected override void OnPaint(PaintEventArgs e)

{

....

}
But the program will not come to this event !!

Can someone help me why?

Thanks

Christian

Have you attached the event handler to your control

myControl += new EventHandler(OnPaint);

Hi Rasika,

Have you attached the event handler to your control:

myControl += new EventHandler(OnPaint);

Sorry, but i don't get what this line means?

Did you mean?:
myControl.Paint +=new PaintEventHandler(myControl_Paint); ?

But i think that Christian have inherited TextBox class
so he could access Paint event by overriding OnPaint(...)
method.

I think the "key" is that TextBox class have Paint event
hidden in events list.

I tried "OnPaintBackground" and it is not fired too.

Strange things are going in Windows.Controls...

Yes I have inherited the TextBox!

What do you mean with
"I think the "key" is that TextBox class have Paint event hidden in events
list."
Thanks

This event does not show in event/property list of TextBox.
So, i think that Paint event can not be succesfully catched
and OnPaint method is not called, too.
So, OnPaintBackground method seems to be not called.

I think that TextBox designers implements much Paint tricks
and disables it to any inheriting usage.
I found similar problem (not with Paint) when i want to
inherits DateTimePicker control.
