Use attached to reproduce. Workaround: RadTextBox tb = new RadTextBox(); tb.Font = new Font(Font.Name, 12F, FontStyle.Bold); tb.MaxLength = 200; tb.Name = "textBox1"; tb.Text = "<Required>"; tb.Location = new Point(49, 7); var pixels = tb.Font.SizeInPoints * 96 / 72; tb.TextBoxElement.TextBoxItem.HostedControl.MinimumSize = new Size(0, (int)pixels + 6);
This seems to be an issue of the System.Windows.Forms.TextBox. When we set the BorderStyle of standard TextBox to None, using the same font and text results in a cut off text. https://stackoverflow.com/questions/8481333/changing-winforms-textbox-to-borderstyle-none-causes-text-to-be-cut-off https://stackoverflow.com/questions/44546091/italic-characters-bottom-cut-off-in-textbox?rq=1
