c# - How can I Write an Event that Happens when Mouse Scrolls in TextBox?

Question

I wanna change the number of the TextBox when The Mouse Scrolls.
I have a Scroll TextBox But I Don't wanna use that. Is There any Event related to this? Should I write an TextBox Event? If yes, How can I write a textBox event that Happens when Mouse Scrolls?

Answer 1

The MouseWheel event is there alright:

public Form1()
{
    InitializeComponent();
    textBox1.MouseWheel += textBox1_MouseWheel;
}

void textBox1_MouseWheel(object sender, MouseEventArgs e)
{
    throw new NotImplementedException();
}

But it is not visible in the event editor. No idea why..

You can find the full list of events through Intellisense like this:

Enter the Control's name and a dot. Now watch the dropdownlist for the event you need. When you have it write += add press Tab twice. This hooks up the event and creates a stub for it.
