从类本身引发自定义控件的事件

Question

I have a custom TabPage class:

class CustomTabPage : TabPage
{
    TextBox tbCode = new TextBox();

    public CustomTabPage()
    {

    }

    public CustomTabPage(string title)
    {
        tbCode.Multiline = true;
        tbCode.Size = this.Size;  
    }        

    //Something like this...
    private void OnThisControlSizeChanged()
    {
        tbCode.Size = this.Size;
    }
}

What I need for this class is to raise the OnSizeChanged event of the TabPage control when I resize it from where I create the control. The reason for this is when I resize the TabPage control, I want to adapt the TextBox size accordingly so that they stay the same.

Answer 1

class CustomTabPage : TabPage
{
    TextBox tbCode = new TextBox();
    public CustomTabPage()
    {
        SizeChanged += CustomTabPage_SizeChanged;
    }

    void CustomTabPage_SizeChanged(object sender, EventArgs e)
    {
        OnThisControlSizeChanged();
    }

    public CustomTabPage(string title)
    {
        tbCode.Multiline = true;
        tbCode.Size = this.Size;
    }

    private void OnThisControlSizeChanged()
    {
        tbCode.Size = this.Size;
    }
}

Answer 2

this.OnSizeChanged(new EventArgs());
