How can i add a line of text to a multi-line TextBox?
e.g. pseudocode;
textBox1.Clear(); textBox1.Lines.Add(\"1000+\"); textBox1.Lines.Add(\"750-999\
Try this
textBox1.Text += "SomeText\r\n"
you can also try
textBox1.Text += "SomeText" + Environment.NewLine;
Where \r is carriage return and \n is new line
\r
\n
