"<script>alert('#######');</script>"
);

In Asp.net, there are times when you want to pop up some message boxes when you perform an action: alert pop-ups for warnings, confirm pop-ups with confirm and cancel buttons, and prompt pop-ups for entering data. There are two ways to do this.
(1) Use of Alert.
Response.Write(
"<script>alert('Incorrect password!') </script>"
).
(2) Use of Confirm.
Response.Write(
"<script>window.confirm('Do you really want to delete?') ;</script>"
);
(3) Use of Prompt.
Response.Write(
"<script> var result=window.prompt('Please enter a new file name:' ), 'ABC'); if(result!=null) alert('You entered '+result);</script>"
);
