Changing WinForms TextBox to BorderStyle.None causes text to be cut off

Question

i've changed a WinForms TextBox control to have no border.

When i do the bottom pixel row of text in the box is being cut off.

Top: BorderStyle.Fixed3D (default). Bottom: BorderStyle.None

enter image description here

You can see the last bit of text in the un-bordered text box is cut off:

How do i convince a TextBox (who's height cannot be changed), that it needs to be taller?

isn't there a autosize property that you could either turn on or off for that.? you should be able to set the width and height as well unless I am deeply mistaken. — MethodMan, Dec 12 '11 at 21:49
You are, in fact, deeply mistaken. You are thinking of `AutoSize` (http://msdn.microsoft.com/en-us/library/system.windows.forms.control.autosize.aspx). My first thought was that too; toggle it off and on so that .NET gets its head out of its assembly. But `TextBox` has no `AutoSize` property. Also any attempts to adjust the height of a TextBox (e.g. `Height`, `Bounds.Height`, `ClientRectangle`, `ClientSize`) ignore any height changes. The `TextBox` decides it's height for itself and that's that. — Ian Boyd, Dec 12 '11 at 21:56
Try a loo here [another answer](https://stackoverflow.com/a/46564085/3998265) it is pretty similar — Fabrice T, Oct 04 '17 at 12:08

The AutoSize property is there, just inherit from TextBox and you can get to the property:

public class TextBoxEx : TextBox {

  public TextBoxEx() {
    base.AutoSize = false;
  }

}

You can do this in your form:

    private void RefreshHeight(TextBox textbox)
    {
        textbox.Multiline = true;
        Size s = TextRenderer.MeasureText(textbox.Text, textbox.Font, Size.Empty, TextFormatFlags.TextBoxControl);
        textbox.MinimumSize = new Size(0, s.Height + 1);
        textbox.Multiline = false;
    }

Then you say RefreshHeight(textbox1);

Multiline change will force the textbox to "accept" the new size

You can also fix this in the Visual Studio Designer.

Change the height in the minimum size property for the text box. Change to multiline=true, then back to false. The text box will resize and stay fix.

No code changes needed.

This doesn't work in VS 2017. It switches right back. Missing a step? – GrayDwarf Mar 15 '18 at 18:27
VS2013. Maybe 2017 does it different. – JRE Mar 15 '18 at 19:03

This seems to do the trick:

public Form2()
{
    InitializeComponent();
    textBox1.Multiline = true;
    textBox1.MinimumSize = new Size(0, 30);
    textBox1.Size = new Size(textBox1.Size.Width, 30);
    textBox1.Multiline = false;
}
