Hi amar,

Without using any editors it's not possible to display the html tags in Multiline TextBox (textarea).

It will display as html in the TextBox.

If you want to display the html tag then you have use Label control. So that while rendering it will display as normal text with the html formatting.

Or you can use TinyMCE editor.

Save (Insert) and Retrieve (Display) TinyMCE contents from database in ASP.Net
