Pass PaintEventArgs into method

Question

I have the following method in C#:

private string adjustColumnValueLength(String value, int maxLength, PaintEventArgs e)
{
    // Set up our string font
    Syst         


        

Answer 1

You should only call that method from a Paint event handler. I guess you have something in your code like:

private void Control_Paint(object sender, PainEventArgs e) { ... }

You should call your method from there (and nowhere else!):

private void Control_Paint(object sender, PainEventArgs e)
{
    adjustColumnValueLength("value", 10, e);
}

If you don't have that, create a event handler:

this.Control.Paint += Control_Paint;
