Solution 1

That is because '\n' means nothing to the browser - it is just whitespace which can be removed. Consider using string.Replace to change it to an HTML newline:

C#

dr.fContent = txtContent.Text.Replace("\n", "<br />");

Solution 2

Hellow, Generally, textbox won't allow to save formatted text. rather use richtext box control which will allow you to enter the formatted text the retrieve it back. but still you want to do it in a formatted way.. you have enter it as html tags like Text
and so on..

Solution 3

Instead of TextBox, you can use RichTextBox. Refer CodeProject article at: C# - Formatting Text in a RichTextBox by Parsing the Rich Text Format (RTF)[^]
