I am newbie to .Net and I got a quick question. In my web form I have 3 textboxes that should be validated on menuItemClick in the server side. How that can be achieved. I saw that each textbox has onValidation attribute, but when this validation is executed?
Finally the validation process is clear to me. For a server side validation the following process should be completed. First we create validators and map them to the specific controls. After that we set CausesValidation property of the controls to true. Then on every postback (in my case OnClick event) we check if the Page.IsValid is == to true.
