Question

I made my own custom TextBox control, but now I need to add the AppendText property, does anyone have any idea how to do this? I can’t seem to find any information about this on Google, I can only find how you use it, not how you implant it in a custom control.

Here is the code of the TextBox if anyone is interested http://pastebin.com/iW4xQCai.

In general, you would be much better off inheriting directly from TextBox instead of creating a composite control.

Either way, there should be no problem implementing the AppendText method (there is a difference between a method and a property).

If you are not overriding TextBox, simply add a new method to your class which passes the call to your textbox.

public void AppendText(string txt)
{
    textBox.AppendText(txt);
}

If you are overriding TextBox, this would require absolutely no code as the method would already be inherited.
