A suggestion to all experts:

We should stop attempting to answer any questions if OP does not properly specify type of application, UI library and other relevant detail which would exclude this kind of confusion. All type mentioned in the question should be written in fully-qualified form. We should request it and only answer when OP comply. Multiple failures to specify such detail became a curse of this forum.

You could try holding your breath also.

If they irritate you so much then simple. DON'T ANSWER!!

You did not get it. I do not answer in such cases. I suggest others do not answer. Are you against it?

You need to specify exact type of text box. There are more then one. And tag your UI library.

The solution is pretty simple: manipulate selection.

Solution 2

hi,

In order to add new line, first you need to set the textbox mode to MultiLine. Here is an example.

C#

TextBox1.TextMode = TextBoxMode.MultiLine;
TextBox1.Text = "First Line" + Environment.NewLine + "Second Line";
TextBox1.Text += "\nThird Line\r\nFourth Line";

The results will look like

First Line
Second Line
Third Line
Fourth Line

Solution 3

You can use StringBuilder[^] class AppendLine[^] functionality. Look the example at the bottom of the article.
