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


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?


Solution

  • 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.
