I have a multiline textBox control called "Post." I also have a singleline textBox called "Comment" and a Button called "btnPost."

Whatever text I type in "Comment," It should display in "Post."

Further more, the texts should be saved permanently in "Comment." And also, the texts shouldn't be overrided after posting another text.

Example:- Just like in facebook, when you type a message and click "Post," the message permanently displays on the wall.

Note that the language chosen for creating this website is C#

Someone please help me.. Thanks.

Are you using any database?

no database

To permanently store the text, you have to store it in a database.
First create the database

okay
