pop up message in asp.net using C#

Hi guys, I have add button and when you press it will insert data into database from textbox.
So i want that after inserting data it should give pop up message that "Your data is inserted successfully".

how can I do that?
Thanks

It can be accomplished by using javascript's alert:

Code:

---

//Somewhere in your code...
Response.Write("<script langauge=\"javascript\">alert(\"Your data was inserted successfully\");</script>");
