Are you validating these value before they go into a database?

Yes ...

Solutions will depend on how you are connecting to the database are you using Entity Framework, ADO.NET with dataset's and datatables?

Solution 1

Put a Label Control next to the TextBox Control.
Put an * in the Label Control.
Size the Label Control to the size of the *.
Change the ForeColor attribute of the Label Control to red.

Easy way :-)..Is there any other way?

That's the way to do it.

That's the easy way to do it, but it's not exactly "reusable" for say, 20 textboxes on the form.

I made a custom validation control suite that you can drag and drop on the form, then just tell it which textbox should be required. The control(s) handles the rest, like putting up the red exclamation mark and whatnot. I've got a few validators made up, like RequiredFieldValidator and RegExValidator. It's exandable so you can create any number of different validators you want.

Sorry, I don't have time to write up an article on it! ;)
