Question

I have a set of controls which take inputs, some of them require validation.

However, a few controls at the bottom of this form, don’t actually have anything to do with form itself but still do postback, which requires the form to be validated. This is a hinderence.

I want to be able to trigger a function to update the form view with out having to fill in any information yet.

Stuff like, if i want to add multiple products to a page from a dropdown list but do not want to cause the form to post back, how do I do that?

Answer 1

You have several options, but your question is not yet clear. What controls should not cause postbacks?

1. Most controls have a AutoPostback property which you can set to false(although this is default for the most)
2. Another option is to use HTML controls instead which don’t post back to the server
3. You can also set CausesValidation to false
4. You could use ValidationGroups to prevent validation for different controls
