Inheriting Methods

[Guest]

I have a text box class, in which I want this code to run each time the
textbox gets the focus:

this.Text = this.Text.Trim()

How do I wire this up?

I can wire it up at the form level, but then I have to put the code in each
text box in the Enter Event.

The textbox base class is currently and empty shell that looks like this:

class TextBoxBase: TextBox
{
}

Thanks,

Greg

I wouldn't use TextBoxBase, since there is already a class in the .NET
Framework called that.

class TrimTextBox: TextBox
{
protected override void OnEnter(EventArgs e) {
base.OnEnter(e);

Text = Text.Trim();
}
}
