Collection of custom user controls.

[rpdunn]

Hello all

I am trying to create several controls (textbox, richtextbox, combobox,
etc.) with added functionality (example: change background color on
enter, return to normal on exit). All this functionality is common to
all of the controls, and I'd like a way to create it just once, rather
than once for each control.

To clarify, I have one control declared as follows:

public class DataEntryTextbox : System.Windows.Forms.TextBox
{
...
}

and another declared as:

public class DataEntryRichTextbox : System.Windows.Forms.RichTextBox
{
...
}

They have precisely the same overrides and added functionality. I'd
like to be able to control these overrides from one place and not have
to worry about changing them every place that I implement them.

Any ideas?

Thanks in advance!
Robert
