my problem is that user may or may not selecte Rdbtn_hotelbook (i.e radio button) .

now else should executed which submit data in database . also u can see that Rdbtn_hotelbook.SelectedValue also have valdaition

Code:

---

lbl_error_package.Text = "please select at least one package with either Number of rooms(single/double)"

---

also untill and unless i did not get the userid fromd database it can not insert data to database in table hotel-booking.

so how to deal with it ,??
validation along with option may or may not select

Hello,

It is possible to use the RequiredFieldValidator on your RadioButtonList. Have a look here for more information:

http://www.geekpedia.com/tutorial82_...Validator.html

If you can't proceed with your query, until something is selected, then you need to make sure that the information is provided.

Also, if you can't retrieve the userid from the database, then you need to inform the user of this. You should not continue with the execution of your code.
