Resize textbox and form size according to Text Length

Question

How can I automatically increase/decrease TextBox and Windows Form size according to text Length?

Answer 1

You can try overriding the OnTextChanged event, then changing the Width depending on the size of the text.

protected override OnTextChanged(EventArgs e)
{
    using (Graphics g = CreateGraphics())
    {
        SizeF size = g.MeasureString(Text, Font);
        Width = (int)Math.Ceiling(size.Width);
    }
    base.OnTextChanged(e);
}
